When you turn on the headlight switch, you are turning on 2 circuits. The headlights are on one circuit and the other circuit is the tail lights and the dash lights. The tail lights are on a separate fuse and the dash lights feed off that circuit with usually a 5 amp fuse also. Sometimes when the dash lights don't work, the dash light fuse is blown. Sometimes the tail light fuse blows and it feeds 12v to the dash fuse. Also a bad headlight switch can cause the dash (and or tail lights), not to work also.
Do you see two green arrows and no dash lights?. A loose ground clip is the suspect and a real pain to fix. A hard slap with the palm of your hand on the hump forward of the steering wheel has turned the lights on every time I have tried it.
You must know all of the bulbs will never burn out at the same time also the fuse controls several other things including those two green arrows.
Check dimmer switch - may be adjusted to extreme dim position May be an open circuit at the dimmer rheostat
Most likely there is a short somewhere in the wiring, and there is not enough electricity flowing in order to operate both simultaneously.
Check the dimmer switch. Otherwise, it may be a fuse problem.
check if the light bulbs are dead ???? By park lights do you mean the running lights or fog lights below the headlights? If so im having the same problem with my 99 SE ... message me if you found a solution. Thanks, bainez
Hook your ingition power wire from the ingition harness to your head light switch (useally Green in color on GM) and it will solve your problem
Check the bulbs they are double filamented with the smaller for stop and turn signals
check the fuse and check all tail light , do not assume all light s are good
1997 gran prix wipe stay in upright possission when shut how to fix
yes. it has a sensor on the dashboard up close to the windshield. when the light is low enough, your headlights turn on automatically
I believe most GM cars the daytime running lights can be turned off by applying the parking brake.
Check your fuse.
Bad door switch or bad headlight switch
If your headlights work, but your tail lights don't, your bulbs could be blown. It is possible that you have a shortage in your car.
94 mercury grand marque dashboard, hazard, and tail lights do not work?
Sounds like a blown fuse. Quick, cheap and easy fix. If not the fuses are fine then it may be a bad headlight switch.
how do i fix my daytime running lights on my 2001 grand prix gt headlights work perfect
All fuses are under the hood, next to the battery.
The dim lights on a 1994 Grand Prix could go out when the headlamp switch is on if there is a short in the wiring for the headlights. There could also be a problem with the bulbs themselves if they were touched during installation. The oils in the fingers can short out new headlights.
yes, they are always on. as in most gm vehicles they have daytime running lights.
It is the same as the switch to turn on the headlights. Pull it out toward you.
