Question about 1988 GMC S-15

1 Answer

Tail Light Malfunction

When the headlights are turned off the turn signals work perfectly. When the headlights are turned on the front turn signals blink out of sequence. Additionally the right rear tailight is lit as if the brakes were on and the left is fine but neither rear turn signal will work.

Try looking for the spot where all your wires come together, near the rear bumper. I was having the same issues until I found the problem today and fixed it. I found a loose ground to the frame the bolt holding multiple grounds was loose. I found it near the rear bumper. I tightened it up and everything started working correctly. Good luck, hope you can find the problem.

Tail lights stopped worked


The tail light or parking light is a different circuit from the turn signal and brake.
The tail light is the same as the parking light in front.
It could be a fuse or a problem with the headlight switch.

The tail lights do not work. The headlights, blinkers, and brake lights work. I checked the fuses and they are all good.


It can be faulty tail light bulb or its issue with tail light control switch or its wiring's are short.

Check the voltage at fuse slot of tail light.Do you receive 12 volt there.If not,then it says tail light switch is not receiving power supply.

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.

Chevy S10. When my running lights are on everything works (except turn signals), front lights, tail lights brake lights. When I turn on my headlights turn signals still dont work everything comes on fine...


Check the grounds on your wiring.
If you have a trailer harness, make sure there are no shorts, or crusty connections

Good Luck chasing the gremlins

My left headlight is out. replaced it twice. High beam works with both bulbs. My tail lights come on but left one doesn't blink when left turn signal is turn on. Front turn signal works fine


Sounds like you have a bad left rear light bulb, as far as the Left Front headlight i would check to make sure you have power and grounds at the connector, if you dont trace the wiring down and check fuses , the grounds should be close to the source.

Installed new headlights assemblys. turn signals


check once more the front turn bulbs, connections, fuse if front and rear have a separate one. Once you connect the front turn signal, blinking frequency should normalize.

1999 jeep grand cherokee - brake lights and turn signals working but Right tail light out with all other lights on--HELP??? My 1999 Grand Cherokee has no parking lights in the rear. The brake lights work...


I have taken my car to many shops to solve this problem. Long story short your tail light has a bad circut and entire lamp must be replaced. (Lamp cost approximate $130.00)
