1993 190E Instrument panel

I have tried to search for the answer to my problem in previous posts, but either I am searching for the wrong keywords or I do not know how to describe my problem correctly. PLEASE help. The gauges on the far left hand side of my instrument panel have just died, not the whole panel, only part of it. I have checked all the fuses and do not believe that any are blown. My speedometer, clock, and tachometer all work but the oil temp gauge, the fuel indicator and battery charge gauge are completely useless. This is very strange because everything was working fine just this morning and now this afternoon, they go bad with no warning at all. Any and all help is appreciated, even if you can just point me in the right direction for keywords to use in my search.

These dash panels are composed of circuit boards. More than likely, a solder joint may have burned or something. Removal of the dash cluster, where the gauges are, will give you access to the board. You may have to re-solder the joints.
My dad had to do this on his '90 2.3 to fix his oil guage problem.

Try doing a search on guages or instrument cluster..

Even though the fuses don't appear blown, change them anyway. Those old ceramic fuses can fool you easily.

If that doens't work, then there is probably a circuit board problem.

I agree w/ blackmercedes. The same thing happened to me yesterday! I had the cluster out w/ the whole dash. I put it all back together and the left side of the cluster didn't work. The fuses looked fine but when I went to take out fuse #9 it was burnt. Try replacing it. It's a white 8Amp on my '91 190e 2.6.

Hope it's just a fuse!

Replaced Fuse

Thanks for all the help. I replaced the # 9 fuse and it worked like a charm

Hi Guys

I've got the same problem with my gauges.

Checked fuse #9, it was OK.

Swapped it out anyway and walah, the gauges work!

if you know enough about circuitry id suggest pulling out the cluster carefully and checking the circuit boards on the back for burned traced, I wasnt able to get my guage lights to work and though they might have been runed out after replacing fuses, turnsout the trace that carries power to the bulbs had somehow burned up, i used a peice of 18 guage stranded insulated wire to jump the gaps where the trace was broken, this takes a good amount of skill to do and evem more so with older traces on the board, its very easy to overheat the board and make matters worse by having the trace seperate from the board making you have to attach the wire even further down the trace line, if this is the case I can go into more detail about repairing the traces if youd like
