98 Olds Aurora. My taillights and dash lights and exterier lights won't come on. Headlights work fine, so do brake lights, blinkers, emergency flashers. No lights for the license plate. Checked all the fuses and they are fine, but the "socket" they plug into...3 have no power to them. How do I find a wiring diagram for the car so we can trace the wiring and find out why there is no power to these 3 fuses?

Hi,

If I understand you right based on your post/description, the signal lights would still turn on even if any or both of the flasher relays are removed. Should this be the case, then the signal lights are not getting the power from the flasher relays but from the brake light circuit.

Perhaps your concern is not with any of the flasher, but simply missing or loose ground more particularly with the rear lights. Perhaps you could try determining which of the wires for the brake lights and signal lights (as they come out of the light assembly) would be ground . A test and even possibly a temporary workaround is to hard wire a second ground connection from the determined ground wire of the lights and attach it to any conveniently located bolt or screw to the body. it may be to your advantage to do this on all the rear lights assembly.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

Yop may have a very common problem unique to that year car.
I have two definite fixes for you:
Open the trunk. Look at the wiring harness that is hooked onto the driver side arm that holds the trunk lid to the body. Untape the wiring harness from the edge of the trunk lid back towards the driver rear seat. You are most likely going to find a broken wire or two, prob a green with a red tracer. The repeated action of lifting/closing the trunklid seems to break the brake/tail power wires. If the wiring harness is perfect, no breaks, AND you have a rear spoiler, remove the trunk interior trim that faces the driver side 1/4 panel. Hidden behind a brace will be a small box. This is the brake lamp sensor. If it has failed, you may need to replace this box. Either fix should resolve your issue.

i would chk. break light switch. should be under dash above break pedel arm. emergency flashers will be on its own fuse, turn signals should have own fuse. as far as interior lights surging that could be ground or alt. chk. battery cables make sure clean and tight. not good idea unhooking bat. cable when running, one spark or surge to computer could burn up computer. besides that realy won't tell you anything if a diod is bad in alt. it may not show up until you tax the system. its best to take it someware like autozone, or any major auto parts store and have it chk.

I had the same problem twice before. Solved it the same way both times. In my case it was the Hazard switch at the top of the steering column. It was stuck. I knew it was that because the signal lights had been functioning perfectly until I parked my car alongside the road with the hazard lights on to do some nighttime fishing and sip a little white lightnin'. (just kiddin' about the white lightnin')

When I got back in my car to go, I turned off the hazard lights but I had no turn signal lights! So I kept pushing that hazard button up and down for about 30 times with my left turn signal arm down until it started working again. So after having this happen to me twice, I learned a valuable lesson: Don't ever use hazard signals in this car.
