Hello. So i have a 73 grand am.
Issue 1 No headlights, but has parking, marker lights, ect. I probe the headlight socket with switch on, and all 3 terminals have power. One is a ground so i am lost there.
Issue 2, is none of the gauges in the rally cluster work, except for the tach. They do nothing.
Issue 3, i have no gauge illumination. The other lights in the dash work, like by the hvac, and so forth, but no cluster lights.
Issue 4, did these cars have a foot dimmer switch from the factory? This car has cruise mounted on the turn signal stalk, which also double functions as the high low beam switch. Like a newer car. Click it toward you to make high beams come on. . When i click high beams on, both turn indicators light up, like the high beam indicator.
I have checked fuses and all are working as they should. I dont even know where to start here. Any advice is helpful
