SOURCE: Rear Wiper won't move on 1998 Jimmy

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.

SOURCE: I have a 2005 GMC Envoy and the rear wiper fluid

Check the rear reservoir as this may have a dried plug in the line. Some cheap fluids have blue dye that becomes gelled in the lines and can stop up the electric pump. To free this clog, use ammonia and let it sit for a bit. You may have to blow the lines free and the nozzle may be plugged, use a pin to clear the nozzle, be careful not to break the point off....

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 !

Rear wiper works but when I try use the fluid on the rear it will not work. Front wipers and fluid work okay. What could the problem be?


On the bottom of the reservoir, there are two pumps. The one for the back could be dead. Or a broken line, check for leaks when spraying the rear. Could be bad wires. Swap the plugs and see it the rear works and front does. Wires usually break near the plugs.

Washer fluid on front


Sounds like one of your nozzles is clogged to me. Try this.....Get a spray can of air, like the computer air spray. Stick the long air can nozzle into the spray nozzle. Shoot some air back into the system and see if it frees your clog. When my fluid gets low, mine will get gunk in it and clog to the point of not spraying at all. Compressed air usually does the trick. If not, remove and clean or replace the nozzles.

Jeep wrangler wiper fluid will not dispense on front windsheld but will on the rear


Switch is faulty is the first thing comes to my mind. Your spot on tho in your diagnosis, although you may have two pumps and tanks, one for front, one for rear. I would check all my fuses just to be sure, and I would look at all my waster tubes and make sure they are not clogged, check your nozzles too, as sometimes wax can clog them up.

Neither front nor rear windshield washer fluids are spraying.


Hey Barry, go to your local O'Reilly's, Autozone, or Advance Auto and tell them your issue and ask them for their recommendations..... they WILL help you and it will be much easier than listening and trying to understand what I (or anyone) says on here..

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.
