Where is the central locking pump located? I had seen where it was located in the trunk and where it was located under the rear seat.

I don't see it in the trunk (only the antenna and the sunroof motor).

And I have had the rear seat out plenty of times and I don't remember seeing it there either.

This is for a 1991 W126

Its in the well where the spare wheel is. In a corner, covered by a plastic cover.

The first photo shows the housing bracket for the central locking pump at the right. The second photo shows the central locking pump with the bracket removed.

Thanks guys. Would not have looked there.

I should probably also ask the question and save myself some extra time. For anyone that has chased down these vacuum tubes, where are the t-connections that break off to the various doors? They are slow to operate and thought I would chase them down.

These diagrams might be helpful:

Thanks!

Not the best news. Looks like they would be under the front seats which I think are not easy to get out.

Run the front seats all the way forward for access to the underseat area from the rear.

Will that work? I assumed you would have to remove the carpets.

I've not really explored that area yet so I don't know.

You can peel up the rear section of the carpets. First remove rear bottom bench seat. Unclip plastic sill trims pulling upwards firmly and then you can peel rear section of carpet a bit.
But to be honest, only four bolts to remove the front seats. And then the electrical plugs. The seats are pretty heavy though.
