Question about 1996 Cadillac DeVille
I noticed that the left rear tail light was out so i changed the burnt out bulb. A couple days later I noticed that it was out again but the bulb was fine. I checked all the fuses but cant find a problem. The turn signals seem to blink quicker than usual as well. Where would be a good place to start looking for a problem.
Check to see if the yellow wire is broken at the connection right below the lights. I just had to repair broken wires on both sides where they had broken off at the connections

If you have access to a simple 12 volt test light, you can remove the bulb you replaced, turn on the turn signal and park lights and see if the test light lights up. If the turn signal contact blinks the test light and the tail contact lights the test light, you know your power supply to the bulb is good.
Next you will check the ground.
Using your test light, carefully touch the tail light contact with the test light tip and touch the test light ground to the socket ground. If the ground is good the test light should light.
Let me know what you find and we will go from there.
