Faulty ground to the dash.
Possible ground issue at the taillights.
When i was trying to disable my DRL's (Daytime Running Lights) i pulled the fuse for them and my headlights and instrument lights were flashing intermittently. Check the fuse panel in the glove box and look for the DRL fuse. Check if its blown. Hope this helps!!!
i was wondering whether the switch at the parking brake could affect this problem.
Most likely a fuse.
A bad ground wire will cause dim headlights, or will cause lights not to work.
Press dome override button 3 or 4 times till you here a beep to put headlights and interior lights back on auto
If the engine isn't running, the battery is low. If the engine is running, the alternator probably has a problem. If you are wearing dark sunglasses, remove them and the lights will get brighter. good luck!
probably the fuse is blown.
A short in the low beam circuit.
sounds like a short circuit in trailer plug or wires to it?
your car sucks!
Blown fuse? Damaged buss board?
