Rear Wiper Motor Not Working

[Cedric-the-Van]

Hi there. Been going through fixing random odds and ends and found myself at the rear wiper motor. The switch on the dash lights up normally when pressed to active the wiper, and when fully pressed, the sprayer works fine. I have attached a video in which I hooked up a multi meter (to what I thought the hot wire was) and flipped the switch. The van was in ACC when I tried this but I got a steady voltage going to the motor but no movement, noise, or clicks. Can I assume at this point that the motor assembly is shot? Thanks in advance for any help.

I'm thinking likely the motor is shot. If so, not much of a loss. I've never thought of that rear wiper as very useful. If you remove the motor, you could connect it directly to the battery to see if you get any movement.

Okay great, thanks

I don't know if you checked the correct wires or not.
However there are several threads on rear wiper issues.
Lots of problems with wiring, especially where the rubber bellows are, near the hinges.

Motors are generally fairly stout, transmissions fail as do pivots and you would do well to work thru the various tests to eliminate the variables.
There's a sticky on how to search the forum if your having trouble finding appropriate threads

Alternatively, you could just fire the parts canon and hope for the best.

Personal experience says the delight of doing a proper diagnosis and finding that smoking gun is worth far more than the cost of the parts for the canon.
Especially when you do find a broken wire and the repair only costs time, not wasted green.
Just sayin'

For what its worth, finding power at the motor isn't definitive, as switches generally complete a circuit by connecting to ground, not power.
YMMV

PS: you dont have to remove the motor to test it, just disconnect the wiring connector nearest the motor and do your testing there, to eliminate any potential "vehicle side" issues.
