2 questions (windows and fuse box )

Hey guys 2 seperate questions. I cant find any where in the manual where my fuse box is on my 92 s600? My 2 cigarette lighters work in the back but dont work on the center console in the front seat. Im assuming its a fuse??? Where can I find the fuse box and has anyone else had a problem with the cigarette lighter on the front console?

2nd question. When I roll down my passenger rear window with the center button on the console the window rolls up about 80 percent then stops, i tried rolling it up from the switch on that window but same thing it only rolls up 80 percent then stops and goes back down a litte. Nothing I do makes the window roll up. Except for when I get out of the car and I hit the lock button on the remote which rolls up all windows and locks.

Any ideas on either of these issues?

There are two fuse boxes - one is up front under the hood by the hood hinge on the driver's side. It's a flat-topped box about 6" square with a horizontal lid - sits right next to the brake master cylinder. Just lift up on the big latch and open the lid. The second is on the passenger side of the car, in the trunk above the battery - you should see a small "trap door" on the trunk lining.

My car is a '92 300SE, so I'll be the fuse locations for the "in common" features are the same. Check fuse #16 in the under-hood box. It's 10A and it also controls the glove box illumination - I'm pretty sure this circuit is only live with the key on, but I could be wrong.

As for your window problem - the condition you're seeing is that the "load" sensor on the window motor thinks it sees too much effort required to raise the window - like if it came into contact with someone's arm. The sensor causes the motor to stop and reverse slightly. The window will close when you use the convenience feature (via locking) as the load sensors are "off line" during that method of closing.

I had the same problem and the solution was a new (remanufactured) window motor. They're super easy to change - I just got one from Auto-Zone for about $80 - they had to special order it. The hardest part about changing the motor is getting the door panel off. The motor is held in with 3 screws - I think the heads are torx shaped - you can R&R the motor in less than 30 minutes with the right tools.

To get the window to close without using the convenience feature override, don't press the button all the way down - just to the point where the glass starts to move. That method also avoids the load sensor.

Hope this helps.

Thanks I aprreciate that a bunch. Im going to check the fuse box today because it seems like the cigarette lighter doesnt work on the front console and the right side of the climate control works (but doesnt light up at night) so Im hoping these are just fuses.

The window rolls up now weird but it works now for some reason.

I checked the fuse and the little squiqley part of the fuse looks good and not broke, im assuming thats the way you check those fuses right? So now that it doesnt look like its the fuse what would you suggest?

The climate control light( passenger) doesnt come on when I turn the head lights on, not sure if that relates to the cigarette lighter?

Does the glove compartment light work? If so (and I think it only works with the key on), then the problem is the lighter socket itself, or the wire has disconnected from it up in the dash. This can be a real problem to fix because the console pieces in our cars, if not already in poor shape due to age, are terribly fragile and don't like being taken in and out repeatedly without cracking.

As for the illumination of the climate control - that's a bulb issue, not related to the cigar lighter.

Report back on whether the glove box light works - that's on the same circuit as the cigar lighter.

That 600 you recently acquired has more than one issue, the window rolling up and stopping has to do with either an obstruction or it needs to be re-synced, push the switch to the first dedent it should go up. I think the sync is to get it up and then rock the switch to position 2 and hold it for a few seconds. The safety is disabled when you use the remote!
You have two fuse boxes, one under the hood on drivers side, square cover, snap at front catch in back, the other is in the trunk, behind covered door. The close assist, cell tel, alarm, locks, and some others are there. The front box covers lights etc. The cigarettte lighter could be bad, people plugging things that draw too much. The MB lighter is different, so dont just PEP-Boys it, try one of the working ones. The glove box light could be burned out, your heater illumination is probably a bulb, if the other works. I dont know if those are "front" replaceable, but if you have to get to the switch the dash panel needs to come off (remove radio, remove screws in ash tray housing, lift shifter panel, screws in radio opening, recode radio, and install alarm lead). more work than "Bose" amp

I disagree about the window issue being related to synching the window. This problem can occur due to a binding lift mechanism, or a weak motor. The load sensor is electronic, far as I know - if the motor draws too many amps lifting the window, then the assumption is that there's an obstruction.

Re-synching the motor won't cure the problem if it's mechanical in nature. On my car, once I got the window to the top and pressed to the 2nd detent to synch, I'd sometimes get a pop-pop-pop as the gears in the motor skipped past one another. The worn worm gear in the motor was causing binding issues during the lifting of the window - replacing the motor cured the problem.

As for the glovebox / cigar lighter issue - we need to see if there's voltage in the circuit. If the fuse is good, likely then the bulb in the glove box is bad. Open the glove box, grab the upper edge of the lamp assembly and pull forward (outward) and down slightly. It should pop out and you can check the bulb and the circuit for power.

If the glove box light has voltage, then the cigar lighter socket is either disconnected, or it's kaput. You can also check for voltage in the lighter socket, too - center rivet at the very bottom is 12v+ - the sides of the socket are 12v-. Agree that aftermarket is not the way to go - go to MB and spend the $20 or so that it takes to get a new OEM lighter socket (if this is the problem).

IF your console is still intact and hasn't been butchered by the PO or MB/Indie servicing, the removal is rather detailed. If a bunch of stuff is already broken off due to age or mis-handling, then things are easier.

Standard disassembly - you should approach the issue from this direction first:
1) Remove the trim around the shifter - need a plastic wedge for this or a cheapo plastic putty knife from the hardware store. DO NOT use sharp metal objects like screwdrivers for this effort. The trim fastens at the front and rear - work it out slowly.
2) Remove the ashtray insert (the part where the ashes go)
3) Inside the hole, you should see a small screw - you'll need a right-angle screwdriver to get at it - it has a phillips head - just loosen it a bit and you can then slide the wood front off the ashtray mechanism.
4) Down inside the hole where the ashtray mechanism sits about at the edge of the left and right sides you should find screws that attach the upper portion of the console (that holds the radio and climate control) to the lower part of the console that holds the window switches. Most often, this mounting point is completely busted from previous services where people didn't know the screws were there. They're supposed to be allen-head screws - 4mm I think is the socket size. I think you'll need to pivot the ashtray mechansim towards closing from the open position to gain access to these screws.
5) Once you get these screws out (or verify that they're gone) - simultaneously pull the horizontal wood frame (the one with the window switches) towards the back and lift at the front to clear the upper console area. Be patient and do NOT force this - the parts are old and BRITTLE!

To get the upper console out you have to pull the radio - remember to get your codes for the head unit. Once that's out, there are two screws inside the radio opening that hold the upper console cover in place - remove these. There may also be 2 more screws accessible from inside the ashtray opening again. Once these screws are out, you should be able to then pull from the bottom and rotate the cover to a horizontal position - NOTE it has hooks at the top that engage the dash along the upper edge - while pulling, "hinge" at the top and pivot at the bottom - DO NOT PULL STRAIGHT OUT.

There are wires at the top for all the switches, and in your case, probably all along the sides, too. The ashtray connector is at the bottom.

The climate control unit is held in with 4 screws - remove them and pull the unit out and disconnect the wires on the left and right-hand sides.

AllData says the bulbs are replaceable and that there's 1 or 2 depending on application and that they're accessible from the outside of the climate control case. I don't remember seeing anything like this on mine, and the AllData page shows an example from a 210 chassis car (useless!). I've got a call into someone that will know about the bulbs and I'll post again when I have an answer.

I just heard from my contact and he says as far as he can remember that the bulbs on our model of climate control are only replaceable by opening the case. I'll have a look at my CC unit this evening and see if that's an easy or hard proposition.

It's very likely that if you have to go into the case to replace the bulb that MB isn't going to offer the bulb as a part. However, there are literally TONS of sources on the web for bulbs to repair items like this - Mouser electronics is a good example (www.mouser.com).

I'll let you know what I find out.

ok so now i DONT have the window problem? I dont know how or why but its working fine. I still dont have any light on my climate control (passenger) but it works, and the fuse looks good ont he fuse box. So I'm starting to think that the cigarette lighter is just bad??? And it seems like its going to be a ***** to change that bulb for the climate control??

hmmm, window problem happend again last night. It seems when the rear passenger stops rolling up all the way. Something I noticed was that I cant just hit the windown switch 1 time to make the front windows roll up. I have to manually roll up the front windows when the passenger wont go down. Not sure if they relate to each other?


And can anyone with a w140 or something similar to my 92 s600 tell me what fuse # can be the possible culprit for a bad cigarette lighter? I checked the fuse labeled cigarette lighter. I would assume that is the fuse but I checked it and its not broken or messed up. ANy other idea? Thanks.

Ok update: I was able to take out the ash tray and then pop the cigarette lighter up through the holder BUT I cant figure out how to disconnect it to change it? I can see 2 wires connected to the bottom of the cigarette lighterbut theres no way i can get a tool let alone a finger in there. How do i remove the lighter itself when connected to the hot and ground ( which Im assuming is the 2 wires that it is connected to?)


By the way I checked the fuses and the fuses are good so unless im missing another fuse it seems the fuses are fine. The glove light DOESNT work either which made me think fuse, but I checked fuse number 15 on my car 15 amp, and its good.
