Cadillac Repair: brake and signal lights on a cadillac deville, turn signal switch, rear harness

Question
I have a 1994 cadillac deville and my brake and signal lights do not work. I replaced a bulb and that did not work. I then checked the fuse box and they are all good.What else could it be?

My signal lights a light does come on but it doesn't blink.
What can I DO?


Answer
Hello,

There are many things that could be wrong and without seeing the vehicle all I can do is guess.

As for the brake light problem, could be a connector bulkhead at the firewall leading to the rear harness with a connection problem. Could be a bad turn signal switch inside the steering column.

As for you t.s. lighting, but not flashing, that could be a defective flasher located under the dash.
