faulty wiring or you are accidentally hitting the switch and not realizing it
This is a wiring issue. If the switch were the issue, the light would not turn on at all. Sounds like something is wired backwards, or there is a cross short. If there is a short to ground, you will be blowing fuses and possibly burning up relays. Consult your vehicle's wiring diagram to ensure the aftermarket headlights are wired correctly.
I would check the fuses. if all fuses look okay then check the wiring. if the wiring looks fine i would recommend taking it to a shop.
iT CAN BE WIRING OR BAD HEADLIGHT SWITCH.
blow fuse, bad motor, bad switch or wiring
Check bulbs, fuses, and check for wiring problems
If the headlights flash on and off, there may be a problem with the bulbs or fuses. There may also be a problem with the battery connections or wiring.
It is probably the running lights that are working and the regular headlights aren't working because of the switch or wiring. TAke it to a garage.
Blown fuse and/or damaged wiring loom.
Your wire connection to your headlights from your fuse box might be loose or broken somewhere. Try running a jumper wire from your headlights to the fuse box. If the headlight work when you try this, then your wiring has an open circuit and needs to be replaced, or fixed.
bad ground or wire connection somewhere could be shorted too or bad headlight if its immediate would say wiring trydisconecting plugs from headlights and see what happens
A shot circuit in your wiring loom. You need to get this fixed, if you do not you could end up with an electrical fire in your car.
i would check the wiring for cracks
Trailblazer wiring harness for the headlights is a common failure in the early years. HID lights will also cause the same problems if the wiring harness plugs are weak. www.trailvoy.com for all the answers on these trucks!
The best thing I could suggest would be to check the wiring, fuses and switches.
A 1997 Pontiac Sunfire would have a voltage regulator and it would be found inside the alternator.
it sounds like you may have a short somewhere in your lighting wiring. its grounding out and stalling the motor.
You would not drive it at night or when the law says you must display headlights.
Does the car have fog lights? I have a 2003 Sunfire that the high beams would not work on. This was caused by a short in the fog light wiring. I had the fog lights rewired separate from the harness (about $100) and the problem was fixed.
I would first start looking at the ground connections aroung the headlight area. Follow the wiring harness from the headlights and eventually you will find where one of them is suppossed to be connected to the car body somewhere. It is impossible to tell you for sure where it is. It simple could have come loose or corroded. If all the grounds are connected then the computer module that controls the lights could have a problem. Also check that the wiring harness connections are actually connected all the way. Hope this helps. Good luck.
The correct grammar would be "Why would both of your headlights blow out at the same time".
It would depend on what is wrong with the headlights.
This problem could be caused by a problem with your alternator. It may also be an electrical or wiring issue. It would probably be best to go to a mechanic to find and fix the specific cause in your case.
The headlights go up and down when you turn the headlights on. If they are not going up or down they may be disconnected from the motor. You would have to take the headlights out to see if they are disconnected or not.
try turning your dimmer switch Also check your wiring, in my 89 LX it has the digital dash and that was the problem
