my rear wiper wont quit woring....think it would be the switch or the motor????

Probably the switch.

pop it out of the dash and unplug it.

Mine started dieing this weekend too.

alarm module usually causes this

I already have the fuse out.....but I want to fix it......trying to figure out where to start

its not the fuse, or the motor, it is a relay on the alarm control modual. I have the same problem:

thanks for the site..........im not sure i would be able to replace the relay on my own..........i know i can replace the module now that i know where it is...........but i dont want to shell out the dough for the repair part..........maybe its not that important, after all it has been like that for over a year now and i have been fine.........maybe if i win the lottery :biggrin:

Well I swapped out my board (bought the whole thing from St. Charles for 126.50). It had a different part number then the one I pulled out, but the wippers are now back to normal. I hope this one lasts a little longer then the 50k or so then first one did.
