Hi, I just recently got myself a 2006 pontiac G6 (45K miles). I noticed on the pasanger side, when its dark outside there is like an LED illuminatng the unlock button, so one can easily hit it to unlock or lock the door manually.
However on the driver side, the bulb inside the switch appears to be out. It functions perfectly fine (all doors lock and unlock) but its just annoying that the bulb is out.
I took the door panel off and the wiring looked good (from a visual inspection). There is only three wires (from the wire harness) that plug into the back of the unlock switch. See my second photo I numbered an area 1, 2, 3, that represents the plug from the wire harness with the three wires that make up the plug. Just to check if its a lose connection I plugged it back in (with the door panel removed still) and I jiggled the wires and still no ilumination. The button still worked when I hit it to lock or unlock, just no illumination!
Since its only three wires and its a two way switch (lock and unlock) I would think the bulb does not have a dedicated wire (from the harness). If it did had a decicated wire just to power the LED bulb then the problem could potentially be the harness, but since it only has three wires for the entire module, and since it seems to me there is no dedicated wire to power just the LED, and since the lock and unlock buttons function fine I would think the only problem it could be is the LED. Does anyone agree with me on that?
Below are the photos.
