rear wiper problem

[clocker122004]

Have a problem with rear wiper motor not starting up. At 1st it was intermittent... now it won't go at all. The washer would work but now it won't squirt either. Is there an interlock switch on the lift gate? Sometimes if we don't really close the lift gate hard the inside light will stay on or the door ajar light on the dash will not go off. I thought there might be a relationship between the two problems. Where is the door switch & does it have any adjustments?

Thanks.

somebody must have had this problem

I suspected from the posts here someone has experienced every problem we have had with our '99 mountie. Can anybody help?

Thanks..

When you push the button, does the washer fluid squirt? if so, I'd say you need to look at the motor and/or relays. if not, I'd look at the switch. Ultimately the whole thing is controlled by the GEM, but without being able to see the inputs and outputs, it's tough to tell.

I have the same problem with my '00 Limited. Rear wiper is dead as Elvis.

Fluid squirts OK, it doesn't move. So motors/wiring/relays.

There are a few threads about it, but no step-by-step diagnostic or a schematic. I'm not tearing up my mint interior in the dark.

If the squirter works, then it's getting the signal from the switch to run. The problem there is that either the up/down relays are stuck, or the motor is shot. The only way to check it is to unplug the motor and check for power at the connector. Between the two wires that feed the motor, check for power and ground through them. (If using a DMM, you'll see alternating +/- 12V).
