well for the second time in less then a year. Baby is back in the dealer for the heating and a/c problems last time it was a fuse, not sure what it could be this time. also when we had a bad thunderstorm last week i got about 3 inches of water on the front passenger floor. if i didnt love her so much i maybe tempted to leave her in the middle of nowhere. not sure if anyone else has had these problems.

just thought i would share

 

I would guess the water leaked past the butyl patch on the cowl. And then the water probably shorted out the blower resistor and or blower motor.

 

Trust ChevyMgr. He's right again. I had this problem with the 06 I had. If you search on the site, many others have had it too.
