Big electrical problem - 93 eagle vision
Ok guys, need some help. Maybe someone else had this problem and already knows where to look.
While driving on the interstate at 70mph, all the suddent the Air, heat, blower (hi/low), power windows, air bags, rear defroster all went out. Power locks work, all the lights work, windshield wipers work.
Thought maybe a fuse went out, nope, all fuses ok. Tried checking the relays. All the relays are ok. Appears to be a ground problem. Looked at the manual. Showed where all the ground locations are, but it seems like no direct correlation to the components that I listed above. For example a/c and heater and power locks appear to be on the same ground, so it should be working.
I am an EE and I am kinda stumped. I am pretty sure its the ground that isn't connected which caused a major outage like that. The car runs though and starts, so no engine electronics have been affected.
Thanks for all the help.
