So I'm driving down the road and I decided to push the auto button on my AC (never used this before) and hear a pop like a blown fuse or circuit breaker. Next thing you know the AC is gone and the climate control unit doesn't even light up. Also, heated seats (no light either). I got home and checked my fuses and they all look okay. I guess that I'm off to the dealer tomorrow. I wonder if a relay blew. It' s 2007 with 7500 miles.

I had the EXACT same problem about 4 weeks ago. Turned out to be some o-rings that were causing the problem.

I had warranty service and repair. All is well.

Good luck.
