For a 2001 S80 2.9:

How do I replace the lightbulb that lights up the drivers side temperature selector switch? Looks like there must be two small lightbulbs that illuminate the temperature numbers, as only half (the left half) of the numbers are lighting up now.

Any how to's or advice on how to replace it greatly appreciated!

hi,
this can be a tricky job to do but here goes....
1, remove pen holder in front of gearshift (lever out each side)
2,remove 2 torx 25 screws at the bottom of the climate control module (called a CCM ,its the big unit with the temp controls on it).
3, heres the tricky part... you pull the bottom of the CCM outwards on a angle untill you can get a couple of fingers under each side of the bottom of the CCM then you need to pull the entire CCM unit outwards while keeping it on a angle.
4,it will be tight to pull out but hopefully it came without breaking the 2 spring metal tabs that held it in place.
5,disconnect the CCM (make sure ign key is off first or this will cause trouble codes to be introduced).
6,you will now need to find the bulbs on the CCM and replace them, this may require some dissasembly of the CCM, the bulbs come as part of a coloured holder which has a straight slot on the back to unscrew half a turn with a small screwdriver.
7,put it all back together.

good luck.

Uhmm...I have the same problem ( a LOT of people with 99 S80s are
reporting this, it seems).

I removed the pen holder, and...no torx screws. Just two metal clips
holding the shift bezel on. The CCM seems to be held in by something
else.

The dealer says the dash has to be partially disassembled to get at the
CCM.

Which model year do your instructions work for?

A very detailed set of instructions was posted 11/14/2004
under the heading
"Lights Behind Climate Control"

The cover around the shifter must be removed, not the pen holder.
There are also pictures on www.carstereohelp.com.

Many thanks Mosswings. The post you referred me to is excellent. Great pics at that website, too. With this info I'm now not afraid to do it myself.

Brickboard is great! Incidentally, I kicked in a few bucks towards support of the site...everyone should!
