    ya, I figured that much. I was hoping for something a bit more specific.

    this sollution could of been offered by a four year old. IE: It sounds as if you have a problem with your wipers. ? come on....

  • dvdmw Jan 07, 2009

    what is meant by 'the switch' has gone bad? Is that the stalk on the steering column? I've been so far disapointed with any advice. But don't stop trying. I'm an idiot- be more specific if possible. I did replace the fuses and relays. I think it's the 250 dollar computerized wiper motor. Again, both the intermintent, return home of the wiper function and the washer function quit at the same time. It is definitely connected. DW

    I found my sollution!!! Listen up fellow Saab owners with similar probs. The wiper motor controlls (in a way) the intermittent, and washer pump functions!
    I found a used 2003 Saab motor from a junk yard (75$US), HAS to be 2003 or newer, and installed it. Immediately my wipers worked like new! They return to home, they intermitent, and the windshield washer fluid pump works again! Thank God!
    This was a tough problem and I couldn't find much on the internet for sollutions, lots of the same problem zero solutions. My dad is an electrical engineer and we determined it is a homing switch w/in the motor (wiper moter) that controlls or sends signals. We were also concerned with the harness that goes to the motor cause it looked wet, but never replaced it.
    Hints on the job: Use a sharp screw driver to pop buttons off the wiper arm. Next, Getting the wipers off their spindles took a special tool called a wheel puller. Note the position of the wipers on the windshield if not home (at the bottom) w/ a marker.
    Getting the lower windshield protective/decorative plastic that runs the lower full (left to right) lenght of the WS: Pull the plastic piece off by pushing center (with small screw driver) of retention rings and retracting gently.
    For wiper motor removal, you need to remove the mechanical wiper assembly (very hard). Dont bend the tubes.They attach on the little (@2.5 inch)metal arm that rotates around the wiper motor. At the end of that arm, extends (upward) a double barrel nipple that then accepts the two rods (metal tubes) of the wiper assemply. They are very hard and resistant to popping off this greased balled connector. Inside the assembly is a rubber thing that pops over a metal double circle nipple. first take the top one off, then the bottom. Use a car door panel remover and a screw driver from opposite sides or just two screw drivers to even the pressure out and aimed upward, try not to torque or bend tubes/ wiper assembly.
    We had to use a short blast from a torch to heat it up enough to pop off (winter time). Worked great. takes some effort and strength.

    If you have probs like I explained w/ your 2003-2008 Saab 93, this is the problem. Don't waste time with the dealer. None of them seem to know this problem and start with the washer pump, the wiper assembly, the actual stalk on the steering wheel, the computer. etc. ect. etc.

    I have same problem with 2003 9-3 Vector. I bought a refurbished wiper motor online ($75) and will replace it. Thanks for the details and hints on how to replace. Hope this fixes it for me as well.

  • sisu cy Apr 13, 2009

    I had the same problem, no delay wipers & no squirters. After reading your post I found a used motor on car-part.com for $35 and it did the trick! I'm guessing that your right about the centering switch being the problem. One suggestion...to remove the wiper arms I loosened the nuts a couple turns, then used a pair of large channel locks to squeeze on the back of the arm and the top of the nut, they popped right off. Thanks.

Thanks. Hey guys, I've found the root cause of the problem. Yes you're right it has to do with the wiper motor assembly. But I took it apart, but this means drilling out the sort of rivets or posts. I removed the plastic black cover over the gear case, and inside there's a switch, that switch has a brown lead going one side and the other side goes to the ground of the housing via a brass sort of washer, and this brass washer was all corroded. Just clean it until you get to the brass, inside out. You don't need to remove the motor housing. Remove all the grey silicon sealing, replace with a silicon sealing, drill holes (I used a 6/32 drill) through the posts that used to retain the cover, screw the cover back with self tapping screws (I used #8 size, half inch). And you've got a rebuilt motor assembly.

Hello I have a saab 9.3 SS 04 and had the same problem.

- intermittent wipe doesn't work, at all
- windscreen washers don't work, at all
- "normal" continuous, and fast wipe work, but the wipers
freeze in the middle of the windscreen if you let go of the
control stalk, rather than sweeping back to the resting position
- same "freeze" happens with the manual wipe (push down on the control stalk)

The weird thing is that, this morning, for about 10 minutes, it seemed to fix itself,
partially - the washers started working etc - but the intermittent wipe still didn't work. However not long after that it went back to the symptoms described above.
also if I unplugged my car battery for a minute the washers worked for several seconds but again same problem occurs.

Solution is to replace your wiper motor. its that "simple"
worked for me. The wiper motor has a lot of electronic stuff and seems to control the washer engine.
Good luck.
the bad part is the the wiper motor costed 235€ for me.

thanks to dvdmw I also solved my problem. BIG THANKS!

I have a 2009 gmc sierra, where is the wiper relay location.


The PCB wiper relays are soldered directly to circuit board inside the under hood fuse box.
The windshield wiper/washer switch signal circuits are inputs to the body control module (BCM) and the BCM controls wiper motor low speed operation, washer pump and high speed operation. The windshield wiper/washer switch is provided a low reference from the BCM and each of the switch signal circuits is supplied 12 volts through a resistor and monitored within the BCM. During LOW or INTERMITTENT operation the wiper switch low signal circuit is closed to the low reference circuit through a series of resistors within the switch assembly and the signal circuit voltage monitored by the BCM will depend on the switch contact location to the resistor assembly. During HIGH or WASH operation the high and wash switch signal circuits are closed directly to the low reference circuit within the switch assembly and nearly all the signal circuit voltage will be dropped across the BCM resistors. The BCM controls the wiper motor through the WIPER CONTROL PCB Relay and the WIPER SPEED PCB Relay. During any wiper motor function that uses low speed the BCM supplies the voltage to energize the WIPER CONTROL PCB Relay and battery voltage will be supplied from the WIPER CONTROL PCB Relay through the de-energized WIPER SPEED PCB Relay to the wiper motor low speed control circuit. During high speed wiper motor operation the WIPER CONTROL PCB Relay is energized as in low speed and the BCM provides a ground to energize the WIPER SPEED PCB Relay and the battery voltage is supplied to the wiper motor high speed control circuit. Wiper motor park operation is controlled by the BCM using an input from the park switch within the wiper motor assembly. The BCM supplies the park switch signal circuit 12 volts through a resistor then monitors the circuit. Whenever the wiper motor is out of the park position the park switch signal circuit is closed to ground and nearly all the signal circuit voltage will be dropped across the BCM resistor. When the wiper switch is turned to the OFF position while the wiper motor is somewhere in mid-cycle, the BCM will continue to operate the motor until the wipers reach the park position. If the ignition is turned OFF while the wipers are in mid-cycle, the wipers will stop immediately where they are and the BCM will park the wipers the next time the ignition is cycled ON.

DTC B3715 02: Front Wiper Relay Drive Circuit Short to Ground
DTC B3875 00: Wiper High Speed Relay Circuit
DTC B3922 00: Front Wiper Function Select Circuit
Have it checked for DTC'S - diagnostic trouble codes .

The body control module (BCM) controls the wiper motor based on input from the windshield wiper washer switch. The BCM monitors the wiper washer switch through three separate signal circuits and a ground circuit. The windshield wiper switch high signal circuit is used to determine high speed wiper operation, the windshield wiper switch low signal is used to determine low speed, intermittent, and mist operation through the use of a resistor ladder, and windshield washer switch signal circuit is used to determine washer operation.
The BCM controls the windshield wiper motor through two output controls, controlling two relays which determine the desired wiper speed, high or low.
Your best bet , take your vehicle to a qualified repair shop or dealer . Hooking up a factory scan tool to see what the wiper switch inputs to the BCM are correct and outputs to relays are good .

2005 ford escape wiper and washer has no power. cant hear it engage when on but was working a week ago. how can i troubleshoot it and find the fuse


Hi Justin , Do you know what a SJB - smart junction box is and where it is located on you escape ?
Windshield Wiper Operation
The smart junction box (SJB) supplies power to the multifunction switch from the SJB fuse 25 (20A) when the ignition switch is in the ON or ACC position. The multifunction switch supplies power to the windshield wiper motor for the HIGH or LOW/INTERMITTENT input, depending on the multifunction switch position selected. The SJB also supplies power directly to the windshield wiper motor from fuse 25 (20A) when the ignition switch is in the ON or ACC position for RUN/PARK operation. When the multifunction switch is in the LOW, HIGH, or INTERMITTENT position, power is supplied to the windshield wiper motor, which moves the wipers off the park position. Once the wipers are off the park position, an internal switch in the windshield wiper motor switches to the run/park position which directs power to the wiper switch then back to the wiper motor. This maintains power to the windshield wiper motor to complete the wipe cycle. When the cycle is complete, the internal switch in the windshield wiper motor switches back to the park position. If the multifunction switch is in the LOW or HIGH position, power is supplied from the multifunction switch and another wipe cycle starts. If the multifunction switch is in the INTERMITTENT position, the windshield wipers remain parked until the internal relay in the multifunction switch supplies power to the windshield wiper motor. The internal relay supplies power after a time delay that is determined by the 1 of 9 intermittent switch settings.

Wipers dont work


This is a complex wiper system . Here are all the components involved !
The Wiper/Washer System consists of the following components:
?€¢
Windshield wiper/washer switch


?€¢
Body control module (BCM)


?€¢
Wiper 1 relay


?€¢
Wiper 2 relay


?€¢
Wiper diode


?€¢
Windshield wiper motor


?€¢
Windshield washer pump


?€¢
Windshield washer nozzles


?€¢
Windshield washer solvent container


?€¢
Windshield wiper arm and blade assemblies


?€¢
Windshield wiper transmission


?€¢
WIPER/SW 10A fuse


?€¢
WIPER 25A fuse


Circuit/System Description
The body control module (BCM) controls the wiper motor based on input from the windshield wiper washer switch. The BCM monitors the wiper washer switch through three separate signal circuits and a ground circuit. The windshield wiper switch high signal circuit is used to determine high speed wiper operation, the windshield wiper switch low signal is used to determine low speed, intermittent, and mist operation through the use of a resistor ladder, and windshield washer switch signal circuit is used to determine washer operation. The windshield wiper motor park operation is controlled by the BCM. The BCM recieves an input from the park switch to determine wiper blade position. When the wiper blades are at the bottom of the windshield glass in park position the wiper park switch will open and the circuit will be pulled up to B+ by the BCM. The park signal will be pulled to ground by the wiper motor park switch while the wiper blades are not in the park position.
The BCM controls the windshield wiper motor through two output controls, controlling two relays which determine the desired wiper speed, high or low
Diagnostic Trouble Codes (DTCs)
The body control module (BCM) monitors the voltage on the windshield wiper switch signal 2 circuit for diagnostic purposes. If the circuit is shorted to voltage while the driver is commanded OFF, the BCM will store DTC B3715. If the circuit is shorted to ground while the driver is commanded ON, the BCM will store DTC B3715. Refer to DTC B3715.
It would be best to have a factory scan tool to diagnose this problem . it would make it easier anyway .

Where is the wiper relay


A wiring diagram doesn't show a relay, just a 25 amp fuse in fuse panel under driver's side of dash. Intermittent working is usually from a loose or poor or corroded connection, or the switch is old and tired, or the motor is old and tired.
Here is one way to check, if you have a test light: when the wipers are not working with wiper switch on high, and key is on, pull off the connector to the wiper/washer motor module (in the engine bay, on the firewall) and check if the purple wire has power. If it does, you probably need to replace the module. Inside the module is a park relay switch (to return wipers to down position when turned off) and a circuit breaker between the motor and ground.
If the purple wire does not have power when key is on and wipers on high, the connection is lost between the switch and the module, or the switch may be malfunctioning. The switch has 5 wires, white wire from 25 amp fuse (power in to switch), a pink wire (for the washer motor), a purple wire (high speed wipers), a dark green wire (low speed wipers), and a gray wire (for the park relay switch inside the wiper/washer motor module). If you see a yellow wire also at the module, that is part of the low speed wiper circuit (the dark green wire) coming from the park relay switch and then to the motor.
Good luck. Post back if further questions, or need more help.

The rear wiper on my '99 model exped isnt working ,ford global says its the motor and it will cost me P13k . any one who can help me find a mechanic do some repair on this?


what is P13K?

check the fuse first. dealer can hook up NGS Tester and get fault codes to see what is wrong.

Principles of Operation
NOTE: The generic electronic module (GEM) will not activate the rear wiper system if either the liftgate or the liftgate glass is ajar. If either the liftgate or the liftgate glass becomes ajar while the rear wiper is in operation, the GEM will park the rear wiper motor.
There are two distinct modes of wiper operation:
  • Off Mode: In this mode, there is no rear wiper activity, and the wiper motor will be in the PARK position.
  • Interval Mode: This mode is selected when the rear wiper switch is in either the Interval 1 or 2 position. When this mode is selected, the rear wiper motor is driven up onto the glass by activating the rear wiper UP relay. When the wiper motor HIGH/LOW/PARK position input reaches the high position, the UP relay is deactivated and the DOWN relay is activated to reverse the wiper motor direction. When the wiper motor reaches the LOW position, as determined by the HIGH/LOW/PARK position input, the GEM deactivates the DOWN relay and will begin a new wiper cycle 1 to 10 seconds later, depending on the interval position selected.
To engage the rear window washer, rotate the rear window washer selector downward to the WASH position. The rear window wiper will run as long as the WASH position is selected. When the rear window washer selector returns to the OFF, INT 1 or INT 2 position, the washer will stop immediately, but the rear window wiper will continue for two to three sweeps and then return to its previous mode of operation.
The low washer fluid indicator chime warns that the washer fluid level is low. The low washer fluid indicator chime is a single tone with a duration of one second. The chime will sound when the low washer fluid indicator is initially activated.
The low washer fluid indicator warns that the fluid level in the washer reservoir is low. The low washer fluid indicator will illuminate when the washer fluid level is low and the ignition switch is in the RUN position.
The low washer fluid indicator will deactivate when the washer fluid reservoir is filled and the ignition switch has been cycled from RUN to OFF, then to RUN.
Inspection and Verification
  1. The wiper/washer system is a generic electronic module (GEM) controlled system; refer to Section 419-10 .
  1. Verify the customer concern by operating the wiper/washer system.
  1. Visually inspect for obvious signs of mechanical and electrical damage.

Wipers do not work in intermittent position. They do work in low and high speeds but do not automatically return to the park position. They stop wherever you turn the switch off.


i belive that your wiper switch has gone out on the intermittent side. this is a very common problem.
I hope this helps you
Thanks
