Pulled my 88 gta out of the garage after fixing the a/c and trunk pull down motor and took it to the car wash and my windshield wipers and washer fluid sprayer are not working. I checked the wiper fuse under the dash and it is good. Is there anywhere i need to check?

 

Do you have wiring diagrams? You will basically have to start at one end of the circuit with a test light to see where the problem is. Yes, I know, that's over-simplified.

You might just start by trying to wiggle the wiper motor connectors or see if any moisture has entered the motor or electronics.
