Hi,
I replaced the lamp in the center stop light with a known good lamp and I am still getting the "Lamp Defective" indicator

I also do not get the center stop light to illuminate.
What is rather particular, which I failed to point out in my first post, is that the Lamp Defective indicator comes on only after a short time of driving. The first time I hit the brakes after the car has sat overnight the Lamp Defective indicator does NOT come on. Only after I have been driving for a few minutes and hit the brakes does the Lamp Defective indicator come on.
HOWEVER, I have verified that the center stop light itself does not illuminate at all - not the first time I hit the brakes and not after driving for a while.
Where do I go from here?
I have felt around from below, in the trunk area, in the hope of locating, well, I actually don't know what - a loose wire??? I'll try hooking up a voltmeter and checking whether there is voltage across the 2 terminals on the center stop light.
Does anybody know the answer to the following?
- where are the 2 wires for the center stop light routed to?
To recap:
- left / right brake lights work
- all other lights work
- center stop light does not work
- Lamp Defective indicator comes on after car is warmed up.
Many thanks in advance
