Mercedes Benz w124 E220 1995
Hello I have a 95 Mercedes e220 w124 cabrio. I tried to take the roof down today and followed the normal steps of:
Releasing the 2 levers on the roof
Pushing the roof upwards

I then try to pull the red switch back to open the roof and windows begin going down and then the clip/bracket of the rear windscreen releases, and struggles to go up. I can hear the motor trying to lift up the windscreen but for some reason it’s not going up. Any suggestions at all, I’m really lost.
I used the roof about 3 weeks ago and worked completely normal,
Please can someone help, worried about how much this may cost.
If there are any fuses or such related to the roof , please let me know where they are located and what number and how I would know if they are blown.
Would really appreciate the help
Regards
Dan
 
That doesn't sound good. There are so many interconnected processes involved in the roof mechanism that I suspect the most cost effective thing you can do is check the hydraulic fluid level and if that's okay, take it to a good independent MB specialist.

Cayman look to be the kind of place you need, although they are a bit far from Coventry. It also means fighting the perpetual roadworks at J10 on the M25.

Hi
That’s very strange though, it was working perfectly fine 3 weeks ago went down perfectly, and now it’s struggling to go down, very strange.
Odd question , but I haven’t driven the car properly e.g 1 hour , so car battery may have not charged up, would it be a chance it could just be as simple as that? The windows go down and the clip on rear windscreen releases and goes up a tiny bit then struggles to move anymore.
I was hoping it would be an easy fix , i guess not
 
It's possible a low charge battery might cause it, but the windows go down so probably not. You say you can hear the motor whirring, that's the electric motor driving a hydraulic pump. Low fluid or worn seals in the hydraulics may cause the symptoms you describe, in that the hydraulics can lift the rear screen until it meets more resistance then they give up.
It can't hurt to charge the battery and check the fluid, beyond that unless you have a full circuit diagram of the system (motors, switches, interlocks etc.) a good specialist is what I'd be doing.

Ok sure I will get on that asap
Any rough idea on how much this could cost by any chance?
 
Not a clue!

Also by any chance do you know the fuses that are related to the soft top, I want to just check them just in case, but have no clue which one relates to the soft top. Also I heard that there are 3 fuses or so just next to the main fuse box in the engine bay, that relate with the soft top? Is that true ?
Regards
 
I'm afraid I don't know, I've never had a W124. My knowlege is limited to what I've picked up over the years (and Wheeler Dealers!), but if you're prepared to go round in ever decreasing circles at the end of blind alleys, searching for "W124 wiring diagram" or "W124 fuse diagram" on the intertubes may come up with the answer.
