The tail lights wont work when the vechile is on. Brake lights, blinkers, lights on the front of car work, bright lights work. When we turn on the lights the tail lights dont come on? We checked the fuses and put new blubs in. Any help would greatly be appericated.
If you look at the bulbs that work the brake ans parking car lights, you'll see that their is 2 fillaments in side. One is for the brake light and the other is for parking light, and one might be burned out so one will work and the other will not. I would just try to change them and see if that would work. If it don't work some thing in the wire is not working like it should.
Sounds like ground problem- remove tail lights and look for wires going to body -remove screww clean grounding area and replace- both sides. You did not say whether the lights work when car is off? With car off and brake pedal pushed is there any brake lights ? If not procede with above.
