Question about 1987 GMC S-15 Pickup
When the headlights are turned on I have no turn signals, no brake lights, and no running lights on rear of the truck. All fuses are good and everything works with headlights off.
That sounds like a ground problem in the rear of your truck. Check the wires where they come from the harness to the tail lights, make sure they aren't corroded or broken and freyed. You may need to remove the ground wire from the body and clean the contact.
Hope this helps
