H2 wiper trouble

Anybody had trouble with wipers sometimes not working on 2003 H2?

My rear windshield wiper only works on the high setting or not at all. I have not had problems with the main windshield wipers.

Very common. Almost certain you have a bad wiper motor/module. There was a recall on some of the H2's in which they replace the module free of charge. Make sure your truck isn't involved in the recall before spending your own money.
