My headlights wont turn but my parking lights work.


I think if you look at the bulkhead connector to the switch you will see the plastic deforming from the heat. The switch is probably affected as well.n if this is the case, buy a new switch and a new bulkhead connector. Solder, do NOT tape all connection and, please, make sure you change the wires one at a time!

98 regal low bed don't work but the high beams do....????? HELP ME PLEASE


Turn on the low beams and check to see if you have battery voltage at the connectors, if not, check the fuse panels for a blown fuse, if all the fuses check out Ok, The next step is to check the high beam switch, called a multi-function switch on the column. It's not that common for the headlight switch itself to fail, however, the main connector to the headlight switch can and do fatigue, sometimes even melt due to a poor connection. I would check for that first as it is a common problem. Your wiring diagram will give you the wire color codes so you know which wire to test.

I have a 92' Park Avenue that the headlights turn off sometimes and sometimes they don't. Where would the delay switch be if it has one? I'm going to check out the relay switch next, I g


Cant say for sure, but you may be laying something on the sensor that turns the lights on, and causing car to think its night time, and turning on lights. The sensor that controls this is on dash ,drivers side near windsheild.

The interior ligts on my 1989 corvette coupe stays on all the time


make sure the interior light switch is turned off so they only come on when the door is opened(this happens alot),the next thing is it could be a door switch that has a problem thinking its open.you could also have a headlight switch that has an internal problem like a short that is allowing power to the interior light wire circuit of the switch causing the interior lights to stay on.

Cant this DRL module cause the headlights and day light running lamps to quit working. For a brief period, I could use daylight running lamps sometimes in place of my headlights when they quit working. Now...


Do you have tail ligts and side marker lights with drls on? if so you will have only dim headlights. Check fuses, I think the headlights are fused seperately.

Green light on instrument panel


Hiya--the green headlamp logo on the instrument panel comes on automatically after you start up the engine.
The green light comes on when your headlight switch is on 'auto' until you turn it to 'parking lights' or 'full on' function, that'll turn off the green light...it's normal.
The other thing is if one of 2 headlight bulb reach the end of bulb life, the green light will flash on/off a few times then stay off....until you or the garage shop put in new headlight bulb.
