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.

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 .

I'm driving in rain, wipers working good, all of a sudden they quit! I drive for 15 min, check again, they work for a while, then quit again...what in the problem?


If your not familiar with automotive electronics an module control of components , I suggest you take it to the dealer . They have the tools to diagnose this type problem !
The Wiper/Washer System consists of the following components:
?€¢
Windshield wiper/washer switch


?€¢
Body control module (BCM)


?€¢
Wiper PCB relay


?€¢
Wiper high PCB relay


?€¢
Windshield wiper motor


?€¢
Windshield washer fluid pump


?€¢
Windshield washer fluid level switch


?€¢
WPR fuse 25 A


?€¢
WSW fuse 10 A


Low Speed Operation
When the wiper switch is in the low speed position, ground is applied through the switch internal resistor and the wiper switch low signal circuit to the body control module (BCM). In response to this signal, the BCM energizes the WIPER PCB relay by applying battery voltage through the wiper relay control circuit to the coil side of the relay. This allows battery positive voltage from the WPR fuse to flow through the switch input side of the WIPER PCB relay and out to the switch input side of the WIPER HIGH PCB relay. Since the wiper high relay is de-energized and its switch contacts are normally closed to the low speed control circuit of the windshield wiper motor, the motor will operate at low speed.
High Speed Operation When the wiper switch is in the high speed position, ground is applied through the windshield wiper switch high signal circuit to the body control module (BCM) indicating the wiper high speed request. In response to this signal, the BCM then energizes the wiper PCB relay, as stated above, and the wiper high PCB relay by applying ground through the control circuit to the coil side of the relay. With the wiper high relay energized and its switch contacts closed to the high speed control circuit of the wiper motor, the motor will operate at high speed.
Wiper motor high speed operation and the wiper high speed PCB relay can also be commanded ON/OFF by using a scan tool. Refer to Control Module References.

What would cause the windshield wipers on my recently purchased Jeep Patriot Sport work on every speed except the high speed. High speed doesn't work at all.


The intermittent switch has a bad contact in it for the high speed, i would say, most likely will have to replace it.

Windshield wipers


Would need to scan vehicle to insure the wiper speeds are controlled by the General Module or a wiper intermittent relay....if relay...would locate and replace...if general module.....a reprogram or software update could be in order...possibly replacement.

Intermittent wiper


what car, what year? gee? a suz, what?
it can only be 4 things. (all cars)
1: the wiper motor is bad. (it has contacts inside for timing.
2: the wiper shaft is stripped, nah you said both stalled.
3: the wiring is bad.
4: the combo switch for the above is bad.

DIY, with what , no tools? no meter.?
with no tools one can only GUESS,
roll dice, and replace a part.
after spending $500 on parts and the wires are good then what.
yes, buy a meter.

it could be a bad ground wire.

when you turn on most wipers, the combo switch sends
that signal( just 12v ) to the motor.
the motor is self booting, that is , it only needs the start up
and then it self provides its own power,
ive restored wiper motors, many.
then the motor runs until it his the dead spot in ITS, internal
sustain switch and the halts. if the combo switch is off.
but if the wiper fails to return, this is a bad wiper motor.
(overloaded by ice, sure)
the motor can fail 2 ways, but
id say the sustain switch is at EOL. end of life.

this is the most common design.
check your FSM for yours. the factor service manual.
or alldata dot com. sure.

'07 Impala Wipers Work Intermittently


Did you check for voltage at the wiper fuse? My info says that fuse is hot all the time. Use a digital multimeter. Everything off, take a reading across battery posts, the generic spec for a full charge is around 12.6 volts. You should get close to same reading at the wiper fuse, hopefully. When checking voltage at the fuse, use chassis ground not the other leg of fuse. There are wiper relays, those are pcb relays, they are soldered into the fuse box, you can't pull them out. Your bcm is also involved with those relays. Your multifunction switch basically tells the bcm you turned on your wipers, then the bcm controls voltage or ground for the relays. You can see wire color for hi and lo speed voltage. Maybe a problem with fuse box or wiring circuit if voltage is low? I hope this was of some help?

Wipers don't work on intermittent. They run but stop in they middle of the windshield and don't go to the bottom like normal, Then they run again and stop some other spot. When put on continuous they...


Intermittent Speed Windshield Wipers
The intermittent wiper speed is activated with grounds controlled by the multifunction switch inputs to the windshield wiper motor module. The windshield wiper motor module then activates the windshield wiper RUN/PARK relay coil and switches voltage through the windshield wiper high/low relay. The high/low relay remains deactivated supplying the voltage to the wiper motor low speed input and activates the windshield wiper motor. When the windshield wiper motor module receives the grounded input, the motor continues to operate until Hall effect senses magnet to turn off RUN/PARK sense the output to the windshield wiper RUN/PARK software, deactivating the relay and disconnecting voltage to the wiper motor. The windshield wipers remain parked until the windshield wiper motor module completes a time-out and then repeats the intermittent windshield wiper cycle.

  • The intermittent windshield wiper speed does not operate correctly
  • Multifunction switch.
  • Circuitry.
  • Windshield wiper motor.
  • Go To Pinpoint Test D .

Pinpoint Test D: The Intermittent Windshield Wiper Speed Does Not Operate Correctly
Normal Operation During normal operation, the windshield wiper motor receives voltage at all times through battery junction box (BJB) fuse 1 (30A), circuit 65 (DG). The windshield wiper motor also receives power with the ignition switch in RUN or ACC positions through central junction box (CJB) fuse 33 (15A), circuit 1002 (BK/PK). Ground is provided to the windshield wiper motor through circuit 676 (PK/OG) and circuit 57 (BK). The run/park and high/low relays are contained in the wiper motor electronics. Mode of operation is dependant on the signal(s) received from the multifunction switch.
    Possible Causes
  • Multifunction switch
  • Open in circuit 57 (BK), 56 (DB/OG), 61 (YE/RD) or 63 (RD)
  • Windshield wiper motor

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

2000 Chevy Malibu wiper delay and intermittent won't work.


I had this problem (wipers only work on high) with my 2002 Chevy Malibu and had to replace the 6 amp diode (22059733) on the wiper control board. It is connected to the back of the wiper motor and is held on by 3 torx screws.
Radio Shack has them for $2.75 6A, 50V Rectifier Diodes (4-Pack) Model:276-1661
