Hey guys my windsheild wipers are not working right. I have the 1987 K5 tilt steering wheel and intermittent wipers.. I only have high and low. the intermittent dose not work.. and when its turned on the intermeittent spot it like its on low, put it to low stays the same speed and then high it gose to high, to turn it of I have to twist it all the way back pass the off position to the mist spot on the handle and the wipers stop where ever they are on the window. my windsheild washer works but same thing to turn it of I have to twist to mist..

now for the fun part Ive just changed the switch in the colume (that was fun..lol) and the modulare peice under the steering colume and same thing, and I have a new signal lever that I bought 1 1/2 years ago from my old blazer (before I sold it I took it out cause it was the crome one looked better) so I think other then changing the motor I've changed all electrical peices.. They worked when I bought the truck and then even after I changed the handle now something messed up not sure..

so if anyone has any sugestion on what this might be PLZ.. shout away

Thanks....

Your wiper motor is bad if the wipers don't park at this point.

I posters the troubleshooting for wipers in the tech section a while ago

Mine do the exact same thing...

Top, how can it be the motor? The motor only drives the wiper arms, interprets the signal given to it to go or not go.

Im with you Steve if the motor was bad you would think they wouldent work at all.. but I've changed every electrical part other then the motor I beleive and still messed up... If you can explane a little better Top that would be great...

Dunno about the pre 73 motors, but post 73 there is a circuit board in the motor. It does go bad.

Look in the tech section and test your motor. The instructions are there, I posted them a while back.

Crazy... I might have to do that... I didn't even know that the wipers would "park"

Where did you get your motor? Just parts store stock?

Edit: Found one with exchange at Napa for $72.99
I wonder what the odds are of getting one that works from the junkyard.
