I just bought a 2002 SLE. The pilot light in the fog light switch does not work - very irritating. From e-bay I bought a working "assembly" which is the entire air vent and dimmer and fog light switch module unit - see the picture below.

Questions:

Can I just replace the fog light switch ?

Maybe the fog light switch/dimmer control block ?

Would it be easier to just replace the entire unit - including the vents ?

Either way, how do I do it without breaking anything ? What is the procedure, tools needed ?

This thread might help you.

Wow, thanks ! Looks like the R&R is a piece of cake. I'll just replace the entire airvent unit with the working fog light switch in it. By the way - your gauges look cool.

Those arn't my gauges. Ya, looks like you just unplug the unit and plug in the new one. Look over the new one so you know exactly where each clip is and how they work. Less risk of damage. You can then sell off the old one or put it away. But that'* the first step of turning in to someone like me, or worse yet, Billboost. I think I have half a engine sitting in the garage now. I think Bill have 12 cars, all in pieces.
