Is it true that these go out before all the bulbs do on the dash?
All the dash light bulbs are out at the same time on my wagon. The warning lites work as well as the turn signal and hazard warning lites. But the Speedometer, odometer and LCD at the bottom are out. Somebody told me to replace the Dimmer Switch because they are junk...TRUE?

 

Not sure about the reliability of the dimmer switch, but the one in my '97 still works fine and I've had to replace a few bulbs. Do the lights on your radio and climate control unit work, or are they out too? They're controlled by the dimmer as well.

Did the lights work fine and then they all went out at once? If so, you may just have to check the wiring on the dimmer. Make sure it's tight, no gunk buildup, etc. You may have to pop it open to make sure the contacts are clean, too.

 

If none work then most likely the dimmer is bad. They commonly go bad.

 

Well it was the Dimmer Switch. God it's flimsy. It's any wonder why these things go! Compared to an Audi dimmer, the Volvo one is tissue paper. Instead of replacing it I just jumped the Brown/Orange wire and Pink ones. I'll search a boneyard for one but I think all the ones I'll find will be bad.

 

I have one you can have that came out of a 94 850 sedan. as far as I know, it works. I'll test it though. PM me your addy and I'll send it to you once I know it works.

 

Update: I tested the spare dimmer I grabbed and it's bad too. Can anyone else help out here? I sent him a PM and will check the junk yard the next time im there, but if somoene else can help before i get out there, all to the good.
