Question about 1986 Pontiac Grand Am
All warning dash lights came on... Fuel, tack.temp.,and speed gauges wont work. 1997 grand am. The car runs fine other than that. Please help me.
Many times, When electrics act up. it has to do with a ground problem. Fuses must be good you have power. Auto electrics like to have a single wire running to the device and then depend on a ground near by to grounded steel instead of a return wire. Loose grounds have no return and the device acts crazy and will be erratic, and not act properly. No where for the electricity to go. Eliminate the possibility of bad or missing grounds first, then get out an electric volt ohm meter, Start checking voltage, and eliminating things that have proper and constant voltage. Then look for bad devices. Just trying to save you some money. Electrical Trouble shooting can be time consuming and expensive. You can do it. lbreen
