HVAC Control Head Unit
I have a 2005 Mazda 3, the AC continues to cut off on it's own. The higher you set the fan speed the more frequently it cuts off. I took it to a mechanic who said it is the computer or the HVAC Control Head Unit, which costs $600 for the part and about $750 to fix it (with labor). He said you have to get the part directly from Mazda, there is no after-market option available. I decided to look for a part on my own with no luck. Just wondering if anyone has had a similar problem and what you did or what advice you may have. Thanks so much.
