Sometimes when I break and slow down my fan that contols the temp on the inside of the car seems to drop out or slow down. Is this a problem that needs to be checked into or has anybody else who has a GXP has this same reocurring problem. Any help would be greatly appriciated

What is your battery voltage at when the car is off, idling and when this happens? Might want to have the alternator and battery tested.

I know that this is an old post, but I will add my two cents. I had a similar problem when stopping and hard turning. I finally figured out that the condensation resevoir drain was blocked and the resevoir was filling up with water and slowing down the fan when the car was not level, such as when braking and turning. I don't know how so much stuff gets in there. Seems the cabin filter would prevent debris from entering, but it does not. I literally have to pull the rubber boot off under the car and rinse all the crap out of it. If this is your problem, it will eventually burn the blower motor out.

Someone please lock this year old thread.
