GM techs, daily driver wiper question

[68bbnova]

The wipers on my wifes 2002 Chevy Tahoe started to act up today, she claims the would not run on low, then high(but not low) and they don't park correct. The only thing I can duplicate is they don't park( go to bottom and then go up about 3 inches, and the delay times seem to be off, but run in high and low. What part do I need? Is it the Pulse Board Module? Thanks, Sean

I'm not up on the newer stuff but usually when a wiper motor wont park correctly, it's the motor itself.

Before changing anything, CHECK your ground.

GM tech here, what he said, replace the board and you'll be good. Alot of guys keep a spare in the glovebox because they go bad so often.

Thanks, I finally got around to doing the board, listed as a "cover kit" from the dealer. Seems to be working correct now. Sean
