I have a 2008 97x. My A/C works fine in the rear but in the front it won't change between low and high. If it is blowing on low and I put it up to high and put it in neutral and restart the car, it sometimes starts blowing on high. Since the rear works I ruled out a compressor problem. I'm thinking maybe the blower motor but I'm hoping to get suggestions before I spend the money on a new one. Thanks for any help.
