Power Seat Module Removal for 2006 ML500
Hi there,
I have to replace this module. Need to know how to remove it from under the passenger seat. The seat is stuck at the middle and it won't move back and forth. I do have access as it does move up and down.
Any guidance would be appreciated.

Don't know why you think it is the control module, but I can almost guarantee you that there is a coin or similar object which is stuck between the frame and the sliding rail.
I strongly suggest you remove remove the seat and see if there is something blocking it, which is usually on the center console side.
Other things to consider are the adjustment switch or the fore & aft motor could be faulty.

I just go by the code reader. I've removed and replaced all the fuses and relays in the cargo area.
Visually checked for obstructions. All to no avail.
All directions functioning but backward/forward.
Code reader specifically mentions the module is faulty. It'll be great if it's not the module.
Foxwell MB specific is the code reader.

The torque on the bolts are 45Nm or 33 ft. lbs.. If there is difficulty loosening the bolt use a pipe as an extension or use another box wrench that will fit over the other end and turn the wrench around and leverage it against the red points.

Did you move the seat up?
Why won't the wrench fit?
What is the wrench size?
Post photo of why it won't fit.

Remove the front bolts and lift it up about 1 inch or so & wedge something under it to hold it in that position.
Then loosen the rear bolts equally. Then lift up the rear of the seat and wedge something under it to hold it in place.
Then keep loosening the rear bolts and raise as necessary until they are completely out.
Do you understand?

Got the seat out! Literally millimeter by millimeter swapping wrenches and levering up and down back and front of the seat, all at the same time. What a victory!
Thanks Major.

Dead battery and seat too far back, Help
I am having the same problem, only my seat is too far back to gain access with a box spanner. Is there any way an auxiliary 12VDC supply can be given to the front seat to allow the seat to be repositioned to gain access. I have tried charging the battery both directly on the terminals and under the bonnet to no luck, DEAD as a nail... please!

Are both seats unable to move in any direction?
Which seat is the problem?

Thé long shaft was jammed inside the plastic gear. Plastic gear housing is pressed in so cannot be removed. Got a complete track frame. Removed the right track and replaced it. Worked out perfectly. Total cost $70. Plus hours of work, thanks to Covid 19!

Neither seat could move due to no power. I managed to borrow a spare battery and used jumper cables to allow the batteries to equalise. once that happened I managed to get the drivers seat forward to access the bolts. New battery fitted and all is okay, except a new problem; i now have a SRS and other warnings on the dash from unplugging the seat???
