ac problem
 

I recently had my passenger side window replaced on my 89 911 cabr, and when I picked up the car, the power to the ac was not working (no air blowing at all, only for the ac though). The guy from safelite claimed that fuses are often tripped/burned as a result of the window being installed. This didn't really make much sense to me, but he said to have someone look at the fuses and to give him a call if there is a different issue. I checked the fuse box, and it didn't look like there were any burnt out fuses, but I'm not totally sure. Anyone have any idea about what could be going on here or have any other suggestions for me?
