I have an 89 Iroc with the intermittent wiper option. The wipers only work on the high setting. When they first come on, they pulse up a couple inches a few times, and then they operate correctly, (high only) after they first go up all the way. If the module on the motor is bad, is there anywhere to get one of these besides a salvage yard.

The motor seems to work fine. The wife was driving the car when this happened. She was using the wipers on intermittent and they just quit. They would then only work on the high setting. They don't click or anything until the handle is set to high.

Any help here??
Thanks
