Power door/trunk closer
1994 S500. The door closers on the passenger side do not work. Also the trunk pull down does not work. While I can slam these shut I really hate to do that. Is there a manual somewhere that will show me how to diagnose these problems and fix. Driver side doors work great. Also, how do you get the door panels off on a S500.

Try removing fuses #3 & 9 in the trunk for 5-10 seconds & see if the system functions properly again.

its the "close assist" pump over the rear wheel. If it comes back to life after the "fuse" trick it will probably only be temporary. Try doing a search on "closing assist", There is nothing in the doors that you can change. These pumps have safeties and if they dont close properly in two ties the circuit is disabled. I am on my 2nd in 14 years and the dealer has not had the doors open, just replaced the pump and checked to make sure there were no leaks

after the fuses were pulled and reinserted the door worked fine. Trunk still inop. Is it on a separate circut? separate vacum line?

playing with it again
After playing with the trunk lid, I see where the pull down is actually working. Seems that the trunk latch, the flipping part is not engaging without forcing the lid down. maybe out of adjustment of something. will have to see what it takes to get into that part and see if it can be adjusted up just a little.
Thanks again for the help... |

If I remember correctly, Pre-facelift W140s had the trunk lid vacuum hooked with the door locks pump, not the doors servo assist pump (as it is operated on later post-facelift models).
Try resetting also the fuse(s) for the door lock/seat lumbar pump. Even if the door locks and lumbar supports work, the trunk lid function might be disabled.

If the catch in the trunk lid is pulling in, your lower lock might have slipped out of adjustment, pull off the cladding and see!
On the early cars the chrome handle was controlled by the locking pump under the seat, while all close assist was handled by the punp over rear wheel. There was a service bulletin that changed that and tied both handle and lid to the assist punp, but it required a junper a new upper latch, and some tubing re-route |

remove the plastic bolt covers on the rearward trunk panel in front of the trunk latch assembly.
the bolts are probably loose and the latch pushed down too far out of adjustment. Bring the latch up a little by hand and then tighten the two 10mm head bolts and shut the trunk, it will now probably pull the trunk down properly. you may have to fiddle with the adjustment of that latch to get the trunk lid at the proper body line level, but it's another one of those common problems. you can use blue loc-tite on the bolts to keep 'em snug. |
