2000 MB 500SL Convertible

My top does not go up all the way and gets stuck in the middle .... I had the hydraulics fixed and or repaired but it stops.. is there a manual way to put up the top and how do I get my top back up.... when I turn off the engine, top goes back down...

thank you very much for any assistance any can give....

I used to have a 2002 SL500 that also had some convertible top problems.

Yes, you can manually operate the convertible top on a R129.

To open the top manually, you want to always do the following:
1) lower the windows
2) release the rear locks
3) pull up the rear bow (the rear of the top that houses the window)
4) unlock and open the tonneau cover
5) unlock both front locks (they turn in opposite directions)
6) move back the top (hold up the rear bow as you are folding the top into the storage compartment)
7) lock the storage compartment

I think the reason why the top is not working is either the main cylinder is till weak or there is a binding of the convertible mechanisms or there is a bend part.

There is a good guide that may help you: https://www.youcanic.com/u/xfire/troubleshooting-convertible-top-problems

It is on a crossfire which is a R170 but the setup is close to that of R129.

Have you tried spraying some lithium grease on the mechanical parts ?
