Pictures of the Info switch from an 850

To open the switch remove the round dial then the 4 lugs two on each side with a small flat blade screwdriver gently lift the plastic around them easing the case apart, there will be a tiny spring make sure you dont lose this.

Replacing the bulb is a little complex

The small solder lumps need unsoldering to seperate the green circuit board from the white board the bulb will then drop out after unscrewing.

The info switch is kaput. Cleaned it after taking the switch apart refitted it and still no change.

Even though your repair was not successful I think the pictures are quite valuable as it will give others a way to perhaps replace the lamp. The success rate on changing lamps has been fairly low. I am going to go ahead and submit this to the repair database for future guidance.

I took one of these apart tonight, I just installed it and it works but the bulb does not light.

I don't know how to solder with this detail. But it looks like you could cut out that corner of the white plastic with a Dremel, then remove the bulb and holder out the back. Replace, and the green board will hold it in.

Is it the same radio shack bulb that goes in the dash rocker switches?

It should be the same 272-1092 bulb.

Thats exactly what I did, cut the white plastic with the Dremel and replaced with a Grain of Wheat bulb from Maplins which is probably the UK equiv of Radio Shack, didn't even need to get the soldering iron out as the old bulb can be removed from the holder and new one is held in place by wrapping the leads around the slots on the bulb carrier before refitting in to the switch.

Charly, what do you get on the info center display with the switch connected, poor wiper contact usually gives a "No Disk" or something similar on the LCD - Mike

I had Disc at times but mainly the various functions wouldnt work even after changing all the sensors. I think if you got a 12v small bulb and soldered it in you'd be fine.

I took the unit apart after getting a new one which didnt fix the problem. I wanted to see what was going on inside the switch after being suggested the contacts could have been dirty or warn away alas they werent. My 97 T-5 has a fully working info unit seems very heavy on fuel

What does the Info switch do, exactly? My 850 GLT doesn't have one so I'm curious. Also, if Volvo's were all wired for every option, that tells me that I *could* find the parts and install it, right?

There was an option for a function digital display showing below the speed/rpm, I knew some models only had 3 functions never knew some didnt have that [see you learn something new everyday]
