2005 Ford Excursion 6.0L PSD - front wipers & washer pump don't work. Rear is good. Replaced wiper motor. Fuses are good. No other electrical issues.

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.


Did you replace the rear wiper module ?

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

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.

unhook the hose at the rear wiper,test, maybe the nozzle is plugged, or hose bent.

hi there
this is pretty typicalof rear wipers check fuse first to make sure it is good if that doesnt work it is probably the motor which goes out and you can pick one up at your local auto parts store hope this will help you and have a great day

No solution sorry - mine have done exactly the same - will wipe front screen if you mess with the stalk - rear wiper works when you push the stalk forwards or backwards but no washer to either - have you found a solution? Kind regards - Andy

Look for the fuse for the rear wiper motor is a 15 amp mini-fuse , in location # 8 of your POWER DISTRIBUTION BOX in the engine compartment. Check in the PD BOX for; - relay # 8 is the rear wiper down relay , and - relay # 10 is the rear wiper up relay .

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.

1. check the fuse to the rear wiper motor
2. check for power to rear wiper motor at the motor (power wire going in to the wiper motor with rear wiper switch on)
If you have good fuses & have power going in to the rear wiper motor...
3. Pull old rear wiper motor and install a new rear wiper motor.
Thank you please drive thru......

check for power at the wiper motor. If power at the wiper motor but no wiper action then replace the motor. if no power at the motor then use a jumper wire and put power to the motor. Does motor run? if so check for open circuit in the wire someplace.
