Default Electrical question 97 SSE

Dose the HVAC blower motor, Traction control and Heads-Up display have any type of common circuit to each other? (Ground point, Common power etc...) All 3 will always malufunction at the same time??

Thanks
Mike

I appoligize but I'm not an expert at the series II vehicles so this might be a bit vague. There are probably 8 or so grounds through the vehicle. The "main" ones are usually found bolted to the engine and along the front fenders. You may find two that bolt under the ignition module/coil pack bracket. It never hurts to clean them but I think that much more stuff would be failing if this were the problem. The PCM is usually grounded here too.

I looked in my 93 service manual but could not find a common source, splice or ground for the components you mentioned but someone else with more specific experience will have to verify this.
