Hello All,

I am new to this forum so please excuse any mistakes...

Anyway i have a 1990 Chev Silverado, reg cab stepside, manual. It has the 5.7L 350 in it.

I recently replaced the wiper stalk in it as i found the selector switch on the stalk would just spin from delay to high and not engage/click at any notch.

After installing the new stalk i have the same problem it does not engage and the wipers are stuck on high. The only way to shut them off is to unplug the switch under the hood. What is the issue and how can i get the selector switch on the stalk to start engaging?

Any help would be greatly appreciated.
