rear wiper motor or pulse control board

juddspaintballs · 03-21-2006, 09:28 PM

Where can I get ahold of either a whole new rear wiper motor including the pulse board (circuit board that controls it) or just the pulse board for the rear wiper? my motor still works fine (I checked it on 12v battery) but the pulse board doesnt work anymore apparently. my switch is still good since it allows me to still squirt washer fluid on the rear window, just the wiper arm doesnt move.

I need to find a Pulse board for the rear wiper. I'm getting sick of not having one that works. Where can I get a REAR pulse board (the front ones abound but not the rear)

www.rockauto.com How do you know the pulse board is shot?

what else would be shot it just quit moving one night in the middle of the cycle. i took the motor out and put 12v to it and it still cycled so it must be the pulse board. the switch still powers the washer fluid in the back so i dont think its the switch or fuse either. i got the whole motor + pulse board off ebay two nights ago for $62 used.

49-300 pb in Raybestos is the part number for the pulse board on the front wiper motor . I dont know if you can replace the one on the back I have a rear wiper motor that worked when I pulled it off . Also make sure the nut on the end of the motor is tight enough that it is letting the arm move and not just spinning inside . A motor with a faulty pulse board will usually just start working intermittenly . It will work fine for a little while then stop the n maybe work again .

the Rear washer pump is separate from the wiper motor .

thanks, I got a motor and pulse board off a wrecked 2001 blazer cheap off ebay but it turns out the pulse board or motor was not my problem. I've either got a bad liftgate switch or a faulty wire somewhere
