Trailer running lights

SOURCE: 1994 Buick centry tail light and dash lights not working

By the info that you gave, I would have to say (guess) that it would be your wifes headlight switch. Because it is possible for the headlights to still work when the switch goes. The headlights, taillights, dash lights, dome light, and dimmer all work off the headlight switch and only part of the switch can go and the other part still be good and functioning. Hope this helps or at least, head you in the right direction to solve the issue. Best wishes.

The cause of this may be the turn signal switch, the circuits run through this switch.

brake switch on the pedal bad.bad relay. do you have a second fuse box if so check it. look at the wiring see if it is frayed or chafed check the connections.check all the fuses not just the ones labeled brakes.switch the relay with one that you know is good like turn signal and see if the turn signal works then check brakes.use a 12 volt test light check the brake switch and probe the wires. hope this helped if not write back and i'll give you more ideas.

I was told that the bulb blew out when this happened to my car and you have to remove the dashboard to replace it. As far as the heat and air I had to replace the blower motor and the problem was solved. Buy one of those $20 car manuals, that's how i usually figure out whats wrong.

I dont have a diagram but the brake light switch has to feed the turn signal switch, Either that wire has a bad connection, or the turn signal switch is bad. Jiggle the turn signal lever and see if the brake lights try to work.
