I have a 96 aurora, headlights brake lights, blinkers,and hazards work but taillights and dash lights went out. if car sits for awhile (day-week) lights work again untill blinker is turned on then they go back off

trace all the wire sounds like its shorting out on something else


hope this helps

Make sure all bulbs are working. All blinkers, tail lights, brake lights etc. I know you mentioned most of these lights work, however it only takes one light to throw off several others. Trace wiring from each as far as possible to locate a possible break in the wiring (shorts). Also, check the headlights and make sure they are plugged in all the way (even tho they work). Also check all relays. One dirty connection can cause all sorts of problems. Jeeps also are known for their poor wiring and common electrical issues.

Assuming the fuse is ok, I would check for power from the headlight switch.

Turn on the hazard switch to check if the bulbs light up. If they do, the problem is probably with the headlight switch itself.

The headlight power wires are probably touching the taillight power wires.

The fuse to the taillights/running lights?
It can't be a grounding problem if both taillights and dash don't work.
If only taillights don't work, it would be suspicious grounding.

again check all connections in and around fuse boxes and battery. this is a bad wiring set up with varied olds cars 90 and newer when they started using the external postive posts

Is it the headlight or taillight fuse that is blowing?

change h/light switch

how do you know if your lighting module is bad in a 1998 Oldsmobile Aurora?
