Wiper/Turn Signal Problem

[Mike McCloskey]

I have a 99 Tahoe that has a problem with the wipers not operating properly. If I turn them on (mist or normal) then turn them off, they continue to operate for an indeterminate amount of time and then will stop without parking in the down position. I had assumed that it was the wiper/turn signal stalk and assembly so I replaced it. The problem has continued the same. Anyone had this? Any next step? Thanks

Just realized that there is a wiper pulse module board on the front of the firewall that might be the culprit. Going to replace it and see if that is the fix.

That module board is a known problem that causes just what you are talking about.

Have Chevrolet.com check your VIN. There is an open recall for this and I had mine replaced (not original owner) in 2018 by the Chevrolet dealership.

Before u go out and buy a new one or from junk yard. Take a look at the circuit board may have a few cracks in the sawder points. I had a similar issue with my yukon and new to me tahoe which came broken a few minor sawders and fixed the issue.

I bought a new one on Amazon. Took five minutes. Works great. Only problem is the new wiper stalk assembly that I needlessly replace won't automatically turn off after a left turn.

Try what I said with the old part if it works you can get your money back.
