I have a 99 GTP and have been having some electrical concerns. First the display on the radio seems to come and go. It is visible but so jumbled you cannot tell what time or station. (seems to act up more when using the heater)
Then the other day I am sitting at the light when I start feeling excessive cold air...turns out my a/c was on and blowing although the system was off. (I am sure it was off and not on auto either). I have noticed that with heat too at times. It is intermittent, but I am concerned it will get worse. Is this a typical issue? Is it the PCM? The last owner didn't have it secured due to the installation of the CAI. Maybe vibration damaged it? I am out of ideas outside of tracing every wire in the car.
