Need some help with my 99 Mustang GT
Everytime I drive this car, the headlights will turn on when I turn them on and stay on for a couple of minutes(2 or 3 maybe). After that time has elapsed, the lights will go out. After another minute or so they will come back on and turn off when they feel like it until I shut the switch off. When I put my parking lights on(halo's), they stay on with no intermission or problems. When I put the bright lights on they act the same as the headlights. If I manually hold the turn signal towards me to turn on the brights, they stay on as long as I have it held. Can anyone help me to find out what's wrong? I have been to multiple mechanics telling me things from, "We don't know what's wrong" to "I think it could be the dimmer switch". Any help with the issue is appreciated!
Video of the problem:
The current lights are aftermarket; however, I still had the problem with the stock lights. This happens while the car is idling or in motion.
