Do you have windshield wipers that are controlled manually by a switch, or are they controlled automatically by a wet sensor?

Your switch might be bad.

You might have a bad wiper control board.
GM had some problems with the windshield wiper control board (bad solder joints on the connector).
The bad connections tell the control board where the wipers are. It thinks the wipers are in the middle of a pass so it turns on the motor trying to bring the wipers to their resting position.
You can either remove the board and re-solder the connections (should be visible with a mag-glass) or get a new board.
A new board for my 97-99 GMC Sierra costs about $25.
I re-soldered mine and it solved it the problem.
Check with the dealer for a re-call and ask a mechanic there.
Good Luck

Suggested Repair
Check the manual wiper switch and the windshield wiper control board. Faulty solder joints on the board connector can make the module think the wipers are mid-sweep and keep the motor running. Re-solder the visible connections or replace the board, and ask a dealer about a related recall.
Conversation Summary
A 2003 Hummer H2 owner reported that the manually switched windshield wipers turn on by themselves and will not shut off. One reply suggested a bad switch. Another explained that a faulty GM wiper control board, often from bad solder joints, can keep commanding the motor to park the wipers, and recommended re-soldering or replacing the board and checking for a dealer recall.
