no door locks no roof open
I have a 2006 sl500. my door locks, lumbar and soft close trunk stopped working. top will not open, message on dash close partition in trunk when i try to open it. i checked all the fuses all perfect. i have no power to the pse pump. i put 12 volts it runs perfect. pump is good. what next. thanks.

Yep, fuse is probably blown to protect the PSE due to a leak, replace the fuse, then find and fix the leak before you burn up the pump. Check the limit switch for the partition and make sure it's being pushed in all the way, that should be a simple problem.

First thing I checked was the fuse, second thing I checked was the limit switch. both perfect. I am not getting power to the limit switch . therefore no power to the pump any more thoughts. thanks.

Check is you are getting power to the fuse. Then downstream of the fuse. I'd eliminate simple things like broken wire first, before digging deeper.

Large vacuum port, for thin vacuum hose?
On the topic of PSE pump, locks etc
I purchased a 2004 SL55. The pump took on water and failed. It was disconnected when I purchased the SL. Now, here is the issue.....The air manifold does not fit the rail with the large vacuum fitting. When testing for fitment, the one manifold wont snap in because there is a airline in the position of the wide vacuume port. I would like to unlock this mystery. Before buying a pump which appears to be right one
The MB workshop manual shows nothing (WIS)

As my old boss used to say: "All problems with electronics are from the lack of the contact where it is supposed to be, and presence of the contact where it isn't supposed to be".
