Heater problem
2003 Pontiac Bonneville 6 cyl Two Wheel Drive Automatic
Has anyone had experience troubleshooting erratic operation of the heater/AC fan on a 2003 Pontiac Bonneville? The fan works when it wants. It may turn on immediately, many minutes after it has been selected or not at all. It is a problem for all functions (heat/AC and defrost). I suspect a short, but have been unable to find a bad connection. Help on diagnosing the problem is appreciated.
