94 sts right taillights

6 posts in this topic

Passenger side taillights quit working. Brake & turn signal still work.

Thought I would see if anyone else has had this problem before I start yanking wires.

Take a close look at the sockets before spending too much time. Cadillacs of that era could have bad grounds inside the socket plastic. See burn mark in plastic in socket on right. 

The fix is to splice on a new socket.

I have a 98 STS that needs the sockets as Logan stated, I prolonged the agony and bought a little time with dielectric grease because parts are so hard to come by where I live at the end of the world.

BUT, they should be replaced

I would be checking the brown wire that goes inside the trunk. It likely splices in with the left side.

You will also find out if you have the factory trailer harness

If you do that will be spliced in also.

I am thinking the wire is bad somewhere between the splice and the right side taillight. Likely obvious when you find it.

The wiring runs under the plastic trim where the pull down latch is

Well went back to basics and found one of the 300 fuses was bad. Who would have thought there is a fuse for each side.

Thanks for the ideas!
