Hello, my name is***** and i will do my best to assist you.I am going over your story now and will reply back soon with some info,thanks!

Expert:  Lou P. master tech replied 4 months ago.

ok so if the roof has not worked in a long time i want you to keep trying, also open the trunk and make sure the shade is pulled out and secure in the latches that hold it, its called a trunk partition/divider ,so that way nothing binds against the roof.

Customer: replied 4 months ago.
shade?
Expert:  Lou P. master tech replied 4 months ago.

sometimes pressure needs to build in the system. also sometimes if the roof is always in the same position the switches will stick and will not work until the top is manually raised.

Expert:  Lou P. master tech replied 4 months ago.

yes the shade, open the trunk and in the front center of the trunk is a shade with a handle in the middle, it needs to be pulled ot towards the rear and set in the left and right holders.

Customer: replied 4 months ago.
ok I got the shade in the trunk pulled out and sitting in the groves
i thought the flashing light ment something was wrong
Customer: replied 4 months ago.
how do you manualy open it
Expert:  Lou P. master tech replied 4 months ago.

ok so YOU had to pull the shade out?? was it not already pulled out?

Expert:  Lou P. master tech replied 4 months ago.

the flashing light does mean that but there are ways around the flashing light.

Customer: replied 4 months ago.
no but I read that and tried it before we began to chat
Expert:  Lou P. master tech replied 4 months ago.

if YOU had to pull the shade out then close the trunk and try the rood again.

Expert:  Lou P. master tech replied 4 months ago.

oh ok

Customer: replied 4 months ago.
light still flashes
Expert:  Lou P. master tech replied 4 months ago.

ok,in the owners manual it shows how to manually raise the top, do you have the manual?

Customer: replied 4 months ago.
no
Expert:  Lou P. master tech replied 4 months ago.

what we do in the shop is always manually open or close the roof and then retry the operation to see if it works, that way we know if it was just a sticking switch or not. ok ill get you the procedure. that way you can at least get it closed.

Customer: replied 4 months ago.
I want to open it!!
Expert:  Lou P. master tech replied 4 months ago.

ok i thought the top was down.. sorry

Expert:  Lou P. master tech replied 4 months ago.

this will actually be easier :)

so do you see the plug at the roof headliner? its right in the center of the roof trim.

Customer: replied 4 months ago.
Expert:  Lou P. master tech replied 4 months ago.

also just so we are on the same page, you press the switch forward to close the roof and rearward to open it.

Customer: replied 4 months ago.
ok
Expert:  Lou P. master tech replied 4 months ago.

ok so , heres the catch, when you press the switch to the rear the trunk does not open??

Customer: replied 4 months ago.
no you can hear it but no movement
Expert:  Lou P. master tech replied 4 months ago.

the trunk must be closed for the roof to work, fyi, i just want to make sure we are on the same page.

ok, so remove the panel on the right side of the trunk, and lets make sure the pump has fluid in it.

Customer: replied 4 months ago.
ok what kid of fluid if its empty
Expert:  Lou P. master tech replied 4 months ago.

if you have a cd changer its right behind that panel. ok good deal, at least for diagnostic purposes. ill get you the fluid type,

benz part number (###) ###-#### you can get this at napa as well.. it will be a clear hydraulic fluid, not the pentosin blue kind, i know they sell it . so i fear that when you fill the fluid you will find a leak at a cylinder so at this point i would operate it slowly until you hear the fluid squirt out and then stop and see where it is coming from.

Expert:  Lou P. master tech replied 4 months ago.
