I have an 86 S4 non turbo. The car has been a nightmare since I got it 2 years. The other day my oil pressure,coolant, battery voltage, and tachometer gauges stopped working along with my heater blower. I check all my fuses using a power probe and non of them were blown. My heater blower has power at the harness and I have no idea where to go from here. Input would gladly be appreciated.


Thanks

 

Smells like a blown 7.5 amp Meter fuse. I would check the fuse once again. If this fuse was blown then it would prevent the back up lights from working, which would be easy to check.

 

honeslty i never even saw a 7.5 amp fuse. I think it might of fell out or something because i dont have the fuse panel cover on. what about my blower motor, do you think coincidentally the resistor went bad?

 

The gauges and blower motor use the same circuit so if the Meter fuse is problematic then both items would not work. Use the link below to find a pic of the fusebox cover (located about 1/4th the way down the screen).
