1991 F250 Delay Wiper Problems
Just bought a 1991 F250 with a 7.3 liter diesel and my delay wipers don't work. Turning the wiper switch to low position doesn't work either. They only work in Hi with a bit of a delay between cycles. Replaced the switch and bought a used wiper delay module from a guy in Pa. It didn't seem to help. Any ideas, suggestions, or wiring diagrams would be greatly appreciated....
