I have an '87, and cannot figure out the wipers on this. I only have the low speed (high speed works the same as low) and the delay only works on the slowest and fastest setting - there is no happy medium. I've tried about 4 different modules, and have checked all electrical connectors, and even replaced the multiswitch lever as a last resort.

Do I need to replace the motor?

 

Interesting, Wait for the experts here...

I cant help but I'll watch this thread.....
