2000 buick regal headlights are turning off intermittently. Headlights come on but turn off when driving then click back on after different periods of time. No headlights or highbeams. I do have...


When the headlights go out, check for power to the low beams on the orange (RightT) and orange/black (left). If you're getting power, then the problem is on the switching/ground side of the circuit.

The body control module uses the ambient light sensor as an input and the headlight switch. If the light sensor see dark, the BCM provides ground to the control coil in the headlight relay. When the control coil is energized, it closes contacts that provide the ground path to the headlights. Since this is intermittent, I suggest tapping on the headlight relay with a screwdriver handle when the lights go out. It's located behind the glove box. Or, try swapping the relay with a different one and see if that solves the problem

No headlamps on 97 Mountaineer.


Buy 1 bulb and insert in each socket one at a time. If the low beam does not work on either side you know it is not because of the bulb. Then you will have 1 extra bulb for emergencies. Ask at autoparts about a headlight relay for lowbeam. When you wrote that highbeams work on pullback you did not say if they stay on high. You have "Flash to Pass" for highbeam which can be a different circuit. The automatic headlight switch is yet another set of contacts to go bad. You should set "auto" to off so you are not fighting this feature when testing. Good Luck

Highbeam headlights work but no low beam, it is not the switch........?


Check voltage at the circuit box and test the high/low dimmer switch. Corrosion on a ground wire could also be the problem.
