After talking to my dealer, he explained that the windshield wiper has 3 basic speeds with 3 variables for each speed. My 3 variable's control does nothing to affect the speed of the wipers. Does anyone else have this problem?

 

There is a little dial on the lever. if it is on the highest for increment it will seem the same. Turn the *** on the end of the wiper lever.

 

We've tried that, no difference-in fact, we even timed the speeds & found no variation from 1 11 or 111 on the lever.

 

Sounds like a visit to the dealer is in order....see if they can order the part....I would hate to make 2 visits for a simple POS dial.
