1992 300-E m-103 W124 sedan. I posted some questions concerning the problem with inoperative vacumn feed to the door locks and truck. I had the after market alarm disconnected and put back to the factory setting of the orginal alarm for that year. my alarm person said" He was geeting a signal to the locks and said" he suspected the Vacuum pump under the right rear cushion.

Two questions . After looking at the pump it is barried in foam casing so getting to it with out distroying the foam looks impossible. Second how do you disconnect this darn thing . It is plugged in real tight and I cannot figure how to properly unplug it with out braking clips.?

Can some one post some pictures to help me. also does an newpump come sanwiched in the foam?

I would apprciate some help . I hate when things do not work !!!

Bob,
Do a "Search this Forum" on the Tech Help section. Type in "keyless entry for your 124 made easy". This will bring up a post labeled "I did it! Keyless entry for your 124 made easy". Click on this thread. Go to the second post and click on the link http://www.peachparts.com/Wikka/W124Keyless. There are pictures of how to essentially remove the foam pad and vacuum line fittings for the vacuum pump.
The foam pad is essentially a split piece. Per the picture, carefully split and then work the foam pad out. Next, use a small standard screwdriver to raise the clip for the vacuum line connection. All that's left is disconnecting the electrical connections. Please contact me if you have any questions.

Hey Bob,

Do not be afraid to tug on the foam housing! After you see the pics as per Gilles good advice, compress the foam where it is under the seat base frame and pull it to the rear. The foam splits horizontaly then you can get at the connections and continue with the advice in this (your) old post!

Did you check the fuses as suggested?
Good luck - by the way it is better for you to stay on the original post rather than starting 3 threads for the same issue.
