The two bulbs illuminating the trip computer in the instrument panel were burned out. I followed instructions on Bay 13 for removing the panel. Changed out the two burned out bulbs. I knocked loose two of the blue bulbs illuminating the warning lights trying to get the panel back in, plus straining the wires going into the trip computer, but it appears to be working in all modes. When I got it all back together the trip computer bulbs work, but those illuminating the speedometer and tachometer do not. Hard to tell how many bulbs behind the gauges are not working. Did I stress or pull loose a wire, or screw up the circuit board somehow when I knocked loose a couple of the warning light bulbs? I didn't touch any of the others that illuminate further up on the instrument panel. The car is a GLT with the low pressure turbo but no turbo gauge or vacuum line to disconnect. It was a witch getting that panel out and even worse putting it back in. What could I have done to knock out most of the light to the top of the panel? The bulbs I scraped loose trying to get the panel back in were warning light bulbs, and after reinstalling them (had to crimp down on the tiny metal tines a bit to make them hold because they were bent up) they all work.

Darn, now you have to take it out again! Get 3 packages of bulbs from an autosupply store, sylvania makes them. Then replace all of the large bulbs. And don't forget to remove the "service" bulb.

Try to get the left side of the dash higher this time to give yourself more room to work with. Yes, the instructions on Bay13 ignore the computer wiring, but you caught it OK. 2nd time is easier, just lower the steering wheel.

Doh! I should have done that when mine was apart. At least I can reset mine ('95), but this would have been far superior. I assume you need a scan tool on the '97, and the cabin switches procedure came in a few years later?

If it's any consolation, you're not the only one to experience this. After replacing the odometer gear in my 850 I found that three of the four backlight bulbs (iluminating the speedo and tach) were out. I figured that that I must have jostled the filaments a bit too much or something.

The bulbs are standard type bulbs. Advance Auto only had that particular bulb in a generic Chinese made version but Autozone sold me the OE "OSRAM" brand bulb packaged by Sylvania.

Has anyone tried getting their hand up the back of the dash to remove these bulbs or is it impossibley tight?

The latter. Absolutely impossible. No room for even trained insects to get back there.

I don't care how small your hands are, or how long your forarms are, you cannot do it from there. Even if you take the kneebrace out first. It only takes 30 minutes to raise the dash and get the cluster out, if you are as slow as I am.

Of course, if the garage is warm, it helps a lot.
