I have a 2007 H3, and I was diving in the rain with the wipers on high and when the rain slowed I switched them back to low. The problem is that when I switched the back to low or delay wiping the wipers just froze and did not move. They only worked on high, I had to turn them off then on for them to work again on low. Has anyone else had this problem?? Also, water leaking out of the Onstar Mic. Still have one month of warranty.

 

Have the whole truck looked over now while your still under warranty. The onstar mic thing is common, but get it fixed asap.

 

Dealer time. They will likely have to replace the multifunction switch to fix the wipers and clean your sunroof drains out to stop the leak. Lot's of threads on leaks if you search the forum.
