Unhappy tail lights on 89 buick century

I have a 89 buick century. The tail lights do not work. the flashers work the turn signals work the brake lights work, but the tailights will not come on. Also have a rattle in the front dirvers tire when i hit 55 or more, slight vibration. Any assistance on these matters would be greatly appreciated

Have you checked the fuses and bulbs yet?Cigar lighter fuse I think.If you know which tire is vibrating have it checked for balance and a bent wheel.I would suggest checking all 4 personally.

I would be taking a look at the headlight switch and wiring. Is the switch in column or dash?

dash board, also the dash lights do not work as well as the cigarette lighter, so sounds like it could be the dash wiring doesn't it

A problem exists in the circuit, which may be and is most likely shorted or open. It could be caused by corrosion, heat, pinch etc.

Some things to consider: headlight switch plug melted at that particular terminal...thus causing short. Circuit problem could exist at the fuse block.

A wiring diagram for your year and make/model would really help.

Did you find a fuse labeled for the inst lights? If not keep looking. Those turn lights had a metal strip that grounded them that will break off,esay to see.

It would sound like there may be two problems. The dash lights probably have a problem within the cluster as they are controlled by either a analog or electronic rheostat while the exterior lights are not. You would probably do well to find a wiring diagram for the chassis and do a little wire tracing to locate the problems. Shouldn't be all that hard to find, the circuits in these earlier domestics are pretty simple.

There were quite a few issues back in the day with the Rheostat Connectors "Burning".....The two problems do have one thing in common....The Headlight switch and rheostat both share the same connector.....Power feeds for exterior lighting, and dash lamps are the same......
