Driver's side tail light not working

Recommended Posts

Hi, got a 2003 Boxter a year and a half ago and last week the driver's side tail light stopped working. Changed the bulbs and nothing... Ordered a new housing for the bulbs and the same tail light bulbs are not working. Reverse, break and signal do work. Any help is greatly appreciated! Do you know which fuses should I check?

By housing I presume you mean the circuit board like thing that the bulbs and wiring plug into.


Your description says there are two functions that may not be working. One is a fog light and I presume you know that is only one side of the car and not both. I forget which. But if one is lit, you ignore the other. The other is what are sometimes called running lights. The light that is lit when the headlights are on and the brake lights are off. That is likely to be a connection at one end of the harness or the other assuming the other side is working. Could also be a chewed wire in the harness.

You need to see what is there and what is not - at the wires.

You will need a Multi-meter that does DCV (DC volts) as well as ohms (resistance).

Check for power (lights on) and grounds with DCV. Then trace back where you lose the signal - either a poor ground or a broken/pinched power wire.
