Rear Wiper/Washer System Components
The rear wiper/washer system consists of the following components:
• Rear wiper/washer switch
• Window wiper module-rear
• Window washer pump-rear
• RR WIPER 15A fuse
• RR WPRB 25A fuse
Rear Wiper/Washer System Operation
The rear wiper module controls rear wiper motor operation. Battery voltage supplied to the module is used to operate the wiper motor in all modes and to return the rear wiper arm to the park position after the ignition is turned off. Accessory voltage supplied to the rear wiper/washer switch is used to supply the rear window wiper and washer switch signal circuits. In wiper switch positions 1 and 2 the wiper switch signal circuit voltage level to the wiper motor module determines the wiper motor delay interval. The rear window washer pump supply voltage circuit is used to provide the operating voltage for the rear washer pump for as long as the rear washer switch is pressed. The rear window washer switch signal circuit is used as a wash signal to the rear wiper motor module to operate the wipers during the rear wash operation.
the switch that you turn to ge the wiper to wipe -- controls the power to the wiper motor. You need check the wiring from the switch to the wiper motor -- for break or disconnects. you may have to replace the switch oor install a dash mount switch instead And bypass the stock switch.
I recently tried the DIY service and repair manuals from a website and it actually helped me repair transmission problem in my jcb 3cx site-master.
It would'nt move forward or reverse, engine was good both solenoids for forward and reverse worked, but still couldn't diagnose the problem.
I don't have much technical knowledge but I just followed it step-wise, and now it works perfect! covers wiring, codes, diagrams, torque specs, PCV, everything
got it from www.reliable-store.com
check rear wiper fuse and relay.if wiper motor getting power but do not work.rear wiper motor bad.if fuse and relay okay but no power going to rear wiper rear wiper switch could be bad.
could be a few things so here goes rear window wiper relay rear window wiper fuse motor or the connections are loose or rusted get these checked first hope this helps ivan
Sounds like an earthing problem if you have already checked the relay and fuses. although if they are both controlled by the same stick on the steering wheel it may be lose or have packed up completely. Like you say its strange both are not working.
Start at the route of the wiring to the wipers and trace it all the way until you find the fault if its not the stalk!
