If the head unit was installed improperly when you bought the car, I'm guessing the previous owner had the same problem. As both heat & AC are affected, it's probably a defective climate control unit. Remove it and have it checked. Otherwise, it might be just a bad fuse, or a wiring problem.

But it worked when I got the car and stopped working when I fixed the radio
