My heater/A/C control panel isn't working anymore. It was working intermittently for a while, only blowing heat or cold on fan 5 setting, and turning off my headlights when it went off unless manually turned on, then it went out completely. The rider information display went off and on with the A/C, and now it's off too. Is there a fuse I need to check? Or some other information somebody can give me? I have an aftermarket stereo, and that works perfectly. The A/C and rider information display both worked for several months after the stereo was installed. I did have an issue with the ignition switch when I bought the car, but that was fixed as well, and the A/C worked for 2 years after that. Any ideas?

The modules fail all the time. You need to take it in for diag anyway because of the acceleration issue. Take care of it all at once. Be honest with the advisor, it will be cheaper that way. GL
