The headlights and the tail lights may not be working on the 1981 El Camino because of a mechanical breakdown.
Most likely a fuse.
The dash lights and the tail lights are on the same fuse. In all probability, you have a short circuit in the tail light wiring.
Make sure fuse is installed and not loose - same fuse controls parking/tail and dash lights
Every vehicle that I've experienced this problem in was due to the tail light fuse being burned out. This condition is because the tail lights and dash lights share a common fuse, which makes the dash lights act as an indicator as to whether or not your tail lights are working (although, this doesn't indicate whether the bulbs are good or not).
my headlights work but my taillights and dash light dont work whats wrong
Check your fuse for tail lights. I think the dash and tail lights are on the same fuse so you know when your tail lights don't work. Might have a short or an open in that circuit.
Parking and dash lights also on this circuit - do they work? Check fuses Could also be a bad headlight switch
check the fuses - there is no fuse for the headlights.
Man vehicles have the dash lights and tail lights wired through the same fuse. Check your fuse box for the dash or tail light fuse. Something has most likely caused it to blow.
CHECK THE FUSE PANEL DASH & TAIL LIGHTS WORK FROM SAME FUSE
The most common reason that your dash lights and taillights are not working on your Pontiac Grand Am is blown fuses. Replace the fuses.
It does have both tail lights as well as dash lights
First, check the tail lights. Turn on the headlights and see if the tail lights come on at the same time. If the tail lights come on but the dash lights don't, it's probably either the switch or the bulbs. If NEITHER come on, it could be the switch, the fuse and of course, still the bulbs.
probably the fuse is blown.
Check your tail lights to see if they are working. Some car makers tie the dash lights to the tail lights as a way to warn you the tail lights are out. Alternately, your head light control dimmer has gone bad.
Check the bulbs - they are double filamented larger for tailights and smaller for stop/turn Check the fuse for parking/tail and dash lights
check your ground wires...they might be loose or detached.
If you are talking about the dash lights , check your tail light fuse . they are on the same curcuit
The GMC dash tail and parking lights are on a different fuse from the brake lights. Check the fuses for a possible blown fuse.
short to ground or a blown fuse
Check your fuses again-use test light. Almost always seems to be a fuse when both tail lights and dash lights aren't working at same time. If that fails, check headlight switch
Check to see if the dash lights dim or if the tail lights come on when the light switch is turned on. If these other lights work then check for a headlight relay. Most likely causes are either the switch or the relay.
It controls the headlights, dash lights, tail lights and park lights. You don't repair it you replace it.
The headlight switch has 3 outputs: Headlights, Side/tail/dash and Dash dimer. Output from the side/tail/... goes through the dash DIMMER so if the side/tail/dash switch has failed, the tail lights won't work either. But you were right to check the fuse first. That's a good place to start.
