If parking and tailights are working could be headlight switch--rheostat for dimming control could be bad
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).
Parking and dash lights also on this circuit - do they work? Check fuses Could also be a bad headlight switch
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.
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
probably the fuse is blown.
