I have a 1989 Carrera 3.2 with non-operative automatic climate control. It worked perfectly until recently. Now, nothing happens at all when I turn the knob to any of the positions 1 through 10.
I replaced the circuit board in the module that is mounted on the floor between the seats. After replacing the board, when I turn the knob, I hear a slight electrical hum, but nothing mechanical occurs, fan operating, etc. Any offer of a referral in the San Diego area to someone/shop that has a particular expertise / electrical skills that could troubleshoot this problem would be greatly appreciated.
Thank you!
