Re: sparatic windshield wipers on 88 blazer
Finally someone who shares my pain. I have the sparatic windshield wipers occasionally on my Blazer, but on my S10 the wipers only work on high, and when you turn them off, they stop anywhere on the windshield. I replaced the w/w motor, to no avail, so its the switch. BTW the S10 has 2 speed wipers, the Blazer has intermittent. I may just swap the whole column in my S10 for a tilt one while I'm at it. Should be easy to remove the switch after you get the wheel off. Good luck.
