Windshield Wiper help
The delay functions on my sons 93 base quit working. I don’t have an FSM. I checked the wiper motor cover and the circuit board looks new. Pulled the motor and checked both wiper rods and everything looks fine. Is there a wiper relay I should check? Or do you guys think it might be the switch in the colum? Just don’t want to waste money as a new motor is $200, another wiper motor cover is $100, and the colum switch is around $150 if I can even get one....

Sounds like cover or park switch. You want to make sure contacts are making contact with cover and not corroded. Covers had some problems with water intrusion. Rtv was used to seal replacement cover to motor. Park switch holds contacts and is available separately from dealer.

No the cover is the pulse module. Without pulse it just a plastic cover. The little spring loaded contacts attach to park switch. Park switch bolts to motor. IDK it still sounds like a cover/ pulse module problem. The motor does need to be grounded. You want to check it before replacing parts.

The tan thing with the blue bolt is park switch. There is a metal tab on the cover. It has a hole for a bolt through it. That is the ground for the module, bolt should be about a 1/2" long.

Searching for park switches, and they are hard to find new for the corvette. Plenty out there for the camero but pretty sure they are different. I might have to buy a complete used wiper motor assembly, and see where that takes me.
