You don't say if the parking lights and/or tail lights come on. If the rest of the lights are working. Try replacing the dimmer switch on the floor. It's relatively simple to do and cost about $15.00 depending on where you are

SOURCE: Brake lights don't work on

First check your owners manual for fuse box location and check for any blown fuses. Next check the brake peddle under the dash for a switch, which is mounted to the peddle arm and turns on the lights when the peddle is pressed in. If the switch has worked loose and is not being pushed when you are pressing the peddle the lights will not come on. Hope this helps Fix Ya up.

How disable Twilight on 99 Cadillac Deville

  • Examine the left dash panel to find the headlight switch. This is the control you use to turn the headlights on or off, with the exception of the daytime-running lights.
  • Look directly beneath the headlight switch. You'll see a small lever. This is called the "Twilight Sentinel." Move the lever all the way to the left to the "Off" position.
  • Turn the headlight switch to the "Parking Lights" mode. This icon has a symbol of two small bulbs. The daytime-running lights are now turned off.

    1994 Pontiac Grand am Tailights all work normaly except when the headlights are on and then they don't work at all?

    Could be the headlight switch.
    The switch has two sets of contacts for the parking lights, the park position and headlight position.
    You may need to check the circuit at the switch to see if you are loosing power when the switch is moved from park to head.

    How do i replace light bubs on the dash panel and door button, do i pull the button up or what to replace the light bubs.

    These bulbs last a long time and if they'er all out you might find the running lights ( taillights arn't working too. ( blown fuse) the panel lights are on a separte fuse but they run off of the tailight fuse. the tailights are really all the lights that come on with the headlight switch except the headlights themselfs. Then that circuit entergizes the panel lights thea light the dash gauges the door panels switches the any console lights the car can have. the dome circuit is another fuse that lights the floor and dome ( if their is one) and any landou lights (piller)
    sometimes this fuse is removed or blow and the dash lights don't work, Or sometimes just a few. The cluster can be removed but not all of the bulbs can be bought at the parts store as the lights are to be replaced by rebuilding the cluster and can't be serviced. Agin some of the door switches are made this way also and you have to replace the switch to get a good light in them.

    Tail light doesnt turn on with headlights but works fine as a break light and turn signal, why?

    in the rear lights you may have two bulbs one is the turn signal the other one is stop light / tail light the stop light / tail light has two filaments, one for the stop light (21 watt) & one for the tail light (5 watt) it is possible that the tail light filament is blown, try replacing the bulb to see if that fixes the problem,also check all the fuses as well.......hope this helps......cheers.

    Both headlights on my 1993 Geo Metro went out at the same time. I have checked the fuses and even replaced the headlights but stll both headlights do not work. All the lights work on the car except the...

    have you checked for voltage at the headlight plug and ground there as well if you don`t have power then it sounds like it is the headlight switch itself,usually if it is a relay one or the other will work but the relay can stop working all together,so keep this in mind,
