Rear Wiper won't move on 1998 Jimmy

The rear wiper of my 1998 Jimmy will not move or spray washer fluid. I can hear the motor when I flip the switch, but no movement. There is nothing blocking it and I can manually wiggle the arm.

    just wiggle it. So I gather it has not completely seized.

    you mean move the arm in a full motion from side to side or just wiggle it?

If you can wiggle the arm for at least 45 degrees or  in full motion meaning you have a problem mechanically, rear wiper has self locking when OFF and it shouldn't move. Open the inner panel and check the motor assembly for any abnormalities.
Good luck.

In my 2007 Saturn Vue there is what I think is an air pump which is cracked that one port is not connected to anything.


There is a electric motor that pumps washer fluid . Located in the bottom of the washer fluid tank .
Wash Operation (Front and Rear Wipers)
The front and rear washer systems use the same windshield washer fluid pump. When either the front or rear wiper is in the washer position voltage will be supplied to one side of the windshield washer fluid pump (depending on whether it is front or rear), while the other side of the pump is grounded.
At this point, the windshield washer fluid pump sprays solvent onto the windshield. When the front or rear washer is activated, the BCM receives an input from the switch that is activated. The BCM will control the wipers while in the WASH mode. The BCM will control either the front wiper relay or the rear wiper relay to turn on the wipers. The windshield wipers operate at low speed for 3 swipes and returns to the park position.

When turning on the washers do you hear the motor run ? Have some one try it while you listen at the washer fluid tank ! These pump motors do go bad .
turn OFF the ignition.
Disconnect the harness electrical connector of the windshield washer fluid pump.
Connect a test lamp from the windshield washer pump control circuit to a good ground .
Turn ON the ignition, with the engine OFF.
Press the front washer switch.
Does the test lamp illuminate?
YES or NO !

Why no wiper fluid to rear wiper 2002 ford explorer


the washer pump for the rear window is located in the washer bottle under the hood that the front washer work out of. the pump may have stopped working and needs replacing. have someone operate the rear washers and listen at the washer bottle to see if you hear the motor working. if not then you will have to check the plug connection for the rear washer pump for corrosion, broken wires and power and grounds. if these check out ok then replace the rear washer pump in the bottle.

Windshield washer not working


  1. check your windshield washer fluid level.
  2. make sure you can hear the fluid pump operating when you operate the switch.
  3. If you can hear the pump working and you have fluid in the reservoir but still no spray,
  4. check the washer fluid lines don't have holes and aren't clogged or pinched. check the sprayer nozzles make sure they are not clogged with debris.
  5. if your washer still doesn't work your fluid pump is probably the problem.

Rear window washer does not spray fluid. When I push the rear window washer button, the front washer/wipers turn on. The rear wipers work normally.


I have the same problem with my 2000 chevy blazer as skornec had posted. I kinda already figured the hose or spray nozzle was plugged. But the problem with checking those items is that I don't know where the hose is located to the back wiper. And the only thing that could be I see that could be the spray nozzle doesn't even have holes that washer fluid could spray from. So basically I just would LOVE if someone could please inform this lame brain of where to find the spray nozzle on the rear window and where in the interior of my blazer does the washer hose run.

My 96 Jeep GC windshield washer isn't squirting. I can hear it run when pushing the washer button and I hear fluid running ; but it doesn't spray on the windshield. Also , my wiper blade in the rear window...


your rear wiper motor might be faulty,in the front i would check your fluid level-if it is full and you hear the pump running-check your washer lines to see if they are pinched-usually around where the hood closes

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.

Problems with the front and rear windshild wipers


If you remove the rectangular plastic cover off your windshield wiper motor, you will find a circuit board. Take it out and throw it away, and get a new one. I had to do that to mine this past winter. My buddy, after taking his truck to GM and giving them 300 bucks, got me to change his, and the problem was gone. The board is 20 or 30 dollars.

2005 ford expedition rear wiper


Sounds like a problem within the wiper motor not turning off at rest or not reaching it's rest point to be able to turn itself off, probably needs a new motor. Disconnecting it should have no relation to the front washer operation, you can confirm this by reconnecting the wiper motor to try.

Rear wiper


It,s a good possibility that the motor is bad, but first do this, turn on the rear wiper switch and go to the rear wiper motor and with a screwdriver handle tap on the motor body and see if it moves. Sometimes the brushes in the motor get stuck and tap on the motor body will loosen them up, also make sure you have power going to it.

99 Nissan Quest real wiper runs continually when ignition is on


Principles of Operation
Operation of the windshield wiper and washer is controlled by the front wiper/washer amplifier assembly. The front wiper/washer amplifier input comes from the multifunction switch by means of a voltage divider circuit. A constant voltage is applied to the multifunction switch by the front wiper/washer amplifier. When the multifunction switch is moved into the LO, HI, or intermittent position, the voltage is directed through a series of resistors. This results in various voltages being returned to the module for each switch position. The module then grounds the appropriate circuit, based on the voltage signal received back from the multifunction switch. This causes the wipers to run intermittently, or at the appropriate speed. Voltage is supplied to the wiper motor by the CJB fuse F46 (20A).
When the multifunction switch wash button is depressed, it bypasses all of the resistors returning a full voltage signal to the module. The module then grounds the appropriate circuits to operate the windshield washer pump for as long as the switch is depressed. The windshield wiper speed is dependent on the position of the windshield wiper/washer switch.
Voltage for the windshield washer pump is also provided by CJB fuse F46 (20A).
Operation of the rear wiper and washer is controlled by the rear wiper/washer switch.
Voltage is supplied to the rear window wiper motor by the fuse junction panel fuse F44 (10A).
The rear window wiper motor ground is made or broken by the rear wiper/washer switch. When the rear wiper/washer switch is moved into the WIPER position, it grounds the rear window wiper motor circuit, causing the rear window wiper motor to run once every 10-15 seconds.
Voltage to the rear washer pump motor is also supplied by the CJB fuse F44 (10A). The rear washer pump is directly controlled by the rear wiper/washer switch which makes or breaks the ground for the washer pump motor, depending upon its position.
If the vehicle is equipped with a movable liftgate glass, a liftgate glass switch is utilized to prevent rear window wiper operation when the liftgate glass is open. This same switch also causes the rear window wiper to drop down approximately three inches when the liftgate glass latch is released.
