Suddenly my blower motor ceases to operate, at any speed. Checked the 2 fuses, they are fine. From FSM, I see that there is a fan control amp in between the auto controller and the blower motor itself. Does anyone know where that thing is, and ever had to replace it? I will check later (when I can work on this) to see if the motor is getting any voltage (the display on the controller does show that it is trying to change the fan speed), but if it is not, then that fan control amp might be bad, and I might need to pull it....
