If you have the automatic climate control like I do on my 1998 GTP, you may be hearing the motors that control the temperature doors "Hunting". I don't know why they do it, but they do. I believe there is a signal from the PCM to the motor and then from the motor to the PCM. When the PCM controls the motor, the motor's position is fed back to the PCM. I think the motors are constantly moving around. This is just a guess.
