my '87 300D is falling apart!
All of the sudden I've got all these issues with my wife's '87 300D and I'm struggeling to keep up. Any help on the following would be appreciated:
1) I replaced the right rear inside door panel. It seemed pretty simple, but when I got done, the pneumatic lock system no longer worked and the seat belt alert light (center ceiling by the sun roof controls) started blinking even tho we're buckled in. These two problems started at precisely the same time: no problems before I replaced the door panel, but problems immediately after I replaced the panel. I took it apart and reassembled but but couldn't see how this could be been related other than the door lock arm that connects to the door handle. What could I have done replacing the door panel to cause this? 2) The heater/aircon fan has stopped pushing air. I noticed that a few of the buttons on the env control were acting a little flakey before so I suspect that the problem is just that the env control unit needs to be replaced. How can I troubleshoot this to confirm that the buttons are the source of the problem? 3) Last thing, someone got into the car and tried to break into the glove compartment... in the process damaged the dash, the glove compartment and the lower dash....so I've got to pull it and replace it. How big of a job is it to get this out and back in?...am I biting off too much?...I'm moderately intuitive with car maintenance but I only have a mainteanance manual for my '85 and don't have one for my '87. Thanks for any advice on any of these three issues. -Harv |

I don't know if I'd call that "falling apart" I'd call it a minor electrical issue, normal repairs (probably need a new fuse/blower/relay or something for the fan issue) and "vandalism" for the last one.
All in all those repairs could all probably be made in 1-2 hours. You need to see a car that really needs some love, then you'd be scared!

OK, so I was exaggerating....it is not really falling apart but I've got three troublesome issues all at the same time.
For the comment about an electrical problem...are you suggesting that the combination pneumatic door lock failure & seatbelt alert light are related to an electrical problem? And for the heater blower, if it is the relay, how do I test for that? Or how do I rule out the button controls? Thanks -harv |

Replacing the dash will take you a bit longer --- I think you ought to drive the car down here and after we have struggled it for 3 days; you will want to leave it here. I'll pay for your flight home.
Of course, I would have to hide the car --- my wife would shoot me if I "acquired" another Mercedes.

Replace the fuse once, if it pops again then you have a grounded out courtesy light. If it doesn't, you grounded it out during the installation. |

Anyway, to the original poster, I had a "somewhat" similiar (okay it is just vaguely similiar) in that my overhead inside lights on the warning light display would not go off when in the proper switch position. I replaced the module (the thing between the inside rear view mirror and the sunroof) and I haven't had any issues. Must have been a bad switch\circuit board\etc. in that thing. Yes, there is a circuit board up there. This would be on a w126, of course.

R&R of the lower dash panel and the glove box and its door are easy jobs. The dash is a larger job but has been described in detail in this forum and is not difficult if you have good instructions. I used those instructions when I pulled an uncracked replacement dash from a junkyard car for installation into my '87.
If you do pull the dash, you should take the time to replace all of the climate control vacuum pods. Dash removal is a fairly time-consuming job, not one you really want to repeat any more than necessary. The problem with your lock system could be either an air line or an electrical connector or wire (damaged or disconnected). Remember that the actuators work on air (pressure or vacuum) but can also be triggered by an electrical switch connected to the front door or trunk key switches. The rear doors have only air lines for their locks so I would suspect that before an electrical problem. Can you lock all of the doors by pressing down the driver's door knob? Can you lock all the doors with a key from outside? The door switches (that operate the interior lights) are wired together via the alarm system in a complicated progression that makes diagnosis difficult. As busted says in post #8, check for shorts in the door wiring. You could also have a broken/shorted wire or wires in the B pillar or in the cable that goes through the rubber boot from the B pillar to the rear door. The puddle lamp wiring and the power window wiring is in there as well as the door switch and its wires. The climate control blower problem could be the switch assembly, the transistor speed control, or the fan itself. I haven't had a lot of experience with the 124 system myself; the easiest test may be to find the blower wires and connect them directly to 12 volts to see if the blower is good or not. Jeremy

Thanks for the advice....I'll check the fuses and for a short in the wiring tomorrow.
For the dash, it looks like I'm looking at about $400 for the three pieces (main dash, glovebox, and right lower dash) shipped. Does that sound about right? -Harv |

What year and what color interior? I might have some dash parts I can shoot your way, the top pad is the tough part to get though.
R&R of the dash is probably a 3 in difficulty. Mostly dexterity and being sure you get the defrost unhooked/reconnected properly, and not dropping parts inside. I posted a 124 dash removal thread a year or so ago, no photos though, ... I can take photos of my spare dash if you need any inside photos. Extend the steering first, wheel can stay on, your choice, if you're a heavy person it might be easier removed, I'm not. I agree with the vacuum-pod replacement suggestion. Ditto also on checking the fan/blower first. The wiper assembly comes off to service the blower and the speed controller beneath it, if it isn't the fuse. Pretty easy, probably a 1.5 in difficulty.
