what is going on
Electricam component by component my interior electrical system is failing. First the entire air system quit functioning. No A.C. no heater just blows air that smells like it came out of the motor. Then the auto-lock system and the car alarm stopped working. Then the dome lights, cell phone plug, and cigarette lighter stopped. THEN there is no longer any fluctuation to the idling when I first start the car. Initially it idles high then levels off to a steady idle at least it used to. Now it idles a fast then slow then fast then slow rythem. Now the background lighting to the dashboard, radio window, and shifting panel board is gone. The oil pressure gauge has stopped. The actual pressure is ok though. My car is a 2002 Pontiac Bonneville SE. Anybody got any suggestions??
