    I have the exact same problem. Did you replace the circuit board? and if so, did it fix the problem?



    Thanks.

It sounds like the wiper control module. The wipers on my 2003 did the same thing. After I pulled the fuse for the rear wiper, the front wipers started acting up as well. I had to pull fuses to stop them too. There is a recall on 2003 H2's for this issue. The cover of the wiper module on 2003s for the allows rain/water to get into the module. The cover will be replaced for free, however, in my case since the module was full of water and my wipers were not working, they replaced the module for free also. Not sure how much it would cost to replace on a 2005.

I have a 07 Chevy Equinox. my front washer sprayer wont work. Fuse is good, i ran power to the fuse and the sprayer worked fine. i figured its prob the switch so i replaced it, but it still wont work.
The washer fuse should have power (battery voltage) while the ignition switch is in the RUN position. Verify both sides of the fuse have power. If the rear wash functions them it's not the fuse.

The switch signals the Body Control Module (BCM). The BCM energizes the front washer relay.

Input to BCM from switch is BCM connector C1,24 PK. Output from BCM to relay is connector C4 15 OG.

You need to verify continuity from the the switch to the BCM and from the BCM to the relay.

Comment below for further assistance.

2010 Reg Ford Focus 5 door hatch rear screen wash not working. Front is OK. How do I fix it?
the washer fluid could be empty / the fuse for the wiper blew / the relay went bad /if you tried to use the wipers without clearing ice away you blew the fuse/ if you just put water in instead of washer fluid it's frozen/ if the wiper works and there is windshield fluid in the tank and not water and all fuses are good the pump motor for the fluid went and is easy to change

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.

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.

Rear windshield wiper sprayer doesn't work but the fronts work fine 2002 jeep liberty limited
The rear wiper has its own pump motor. pull the hose from the wiper and have someone engage to see if there is a clog. do the same at the motor. if bo liquid comes out then its the pump. also check fluid level in reservoir as well as a possible secondary reservoir
