dash lights

1) The dash lights on my 87 190E is not working, When I got in and drove it last night thatís when it happen, I turn the head lights on it came on but no dash lights! It worked the night before, so not sure whatís going on.
2) This morning Iíd check the fuse (main fuse box under the hood) it was ok, but changed it anyways just incase thereís hairline cracks, turn the dimmer back and forth a few times, also check the reverse lights it worked ok too.
3) The auto gear shifter light is the only one that works, but I donít think itís in the same path. Iím in the process of moving so I donít have the manuals with me.
4) Iíve been searching the posts, a lot about another fuse behind the instrument cluster, I donít have one if I recall when I took this assembly out to replace the capacitors on the clock.
5) My questions are:
a) Am I looking in the wrong place for the ďfuseĒ that some of you are talking about?
b) If no fuse in my car (87 model but manufactured date Nov 86), what could be wrong?

Thanks for any help

Unhappy Bad news!

I had a problem like that. I ended up taking my cluster to Steve Brotherton to solder some wires behind the cluster. In my case though, I was replacing some lightbulbs and I had a short, since my car does no have a fuse behind the cluster, apparently it fried the "weakest link".
I hope that is not the case in your vehicle!
Good luck!
p.s. Double check for the fuse. It looks like a lightbulb but, it is red.

Still lost

1. It does seem like a fuse thing because the radio, climate control, fan speed and the power window switches are also not illuminating. I canít find this fuse back there I donít think I have one, Iíd unscrew all the black/brown lamp holders and they are all lamps large and small. Could youall tell the exact location for this fuse?
2. I can solder too, I mean look Iíd replace the capacitors on the clock this past summer but I donít think itís a short, because I didnít have the instrument cluster out for any reason since then, it just went, I had the car for over 11 years and this was the first timeÖ I drove it parked it, When I got in and drove it the next night thatís when it happen, I turn the head lights on, they came on but no dash lights! Not sure whatís going on.

The location of the fuse (if you have one) is...

looking at the speedo from behind, it should be in the 1 or 2 o'clock location. From your description, you may not have a fuse. My car had a couple of wires with a short, behind the speedometer. You may also try to replace the light dimmer switch (they do go bad), they are cheap.
By the way, ALL of my dash lights were gone, except for the shifter.
Happy hunting!

Where is X6 on a 87 190E

1. As mention earlier Iím in the process of moving house, I have the body/chassis manual but canít get to the electrical troubleshooting manual.
2. Can anyone tell me where the ďTerminal blockĒ X6 is located at on a 87 190E?
3. When I find this X6, Iím going to jump it with the cigarette lighter lamp, if this works it would pin point the problem to the illumination rheostat/dimmer switch right?

illumination rheostat/dimmer switch

1. Well I guess no one had the time or knows where X6 was located at, and I didnít trace where it went ether it would be to tasking right now.
2. Looking at the wire diagram shows that X6 has many feeds; one is to the radio (main jack, wire #3 gray/blue). I jumped this with the positive side of ashtray lamp (gray/green) and wow I got dash lights!

3. This answered the question, as some of youall might have suspected it was the illumination rheostat/dimmer switch, itís a big job even with my small Thai hands but Iíll go into it soon and see whatís wrong maybe a resolder or a cleaning with an eraser will do the trick, itís already broke so if that doesnít work then I"ll buy a new one. Will let youall know how it turns out.

not the rheostat

1. Finally got this done and no it wasnít the rheostat.

2. I had ordered a new rheostat to replace but it didnít work.

3. Did the soldiering thing on all the joints still no luck.

4. Troubleshoot to the circuit card seams like an open on it, I removed the whole assembly of the fuel, temperature, oil pressure and economy off the card. Not to hard of a job just need to take your time. What Iíve found out underneath was something Iíve never seen before in my electronic world experience but the path was broken also lifted from the board like a broken bridge, wished I had a picture. I think this was the "weakest link" that you have talked about. From here I just pile some solder on top and link them back, now it was good to go!

5. Lessens learned: troubleshoot to the last point before the suspected component in this case I should remove the rheostat and jump the two points to see if I get dash lights if not then go from there.
