Q: Mazda says my a/c system is fine, but it fails every time it really hot?

asked by on September 15, 2017

Mazda put a new compressor in my car $1600 repair, but the hotter the temperature outside the less it works until it fails completely in really hot weather (above 95 degrees). They are in Huntington Beach, so the temps are cooler there, so I am having a hard time replicating the fail of the a/c for them. I just want the system to work, and they keep telling me that nothing is wrong with it, but it fails in hot weather,...Help please
