2000 Bonneville SE Interesting Electrical Problem
 

Hi All,

I have a 2000 Bonneville SE which appears to have some sort of electrical issue with the following symptoms:

1.) Fog lights are stuck on (indicator light on, pushing button does nothing)
2.) "Anti lock" and "Brake" lights are both lit on the dash
3.) No heater or AC control buttons do anything (also, no indicator lights work, these worked previously). Adjusting the fan speed knob changes fan speed, but changing the temperature knob does nothing.

Does anyone have any idea what this could be? Is there a ground that could impact all of these or some other commonality between them? Any help would be greatly appreciated
