Wipers won't work on high

[muddobber]

First the rain sensor on the windshield went bad on my 2009 Tahoe. A week after replacing that the wipers wouldn't work on the high setting.

I replaced the multi-switch and still nothing. The Dealer diagnose a bad wiper motor but replacing that didn't correct the problem either.

Anyone have a suggestion?

Thanks for your help.

If you've already replaced the switch AND the motor (which are two common failure points), I'd have to guess that there is some kind of short in the wiring between the stalk and the motor. Maybe something got severed in your column?
