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.

Going through your instructions, you have to be able to move the seat back and forth, something I cannot do because it is stuck. I can only remove the 2 bolts in front. The 2 bolts at the back cannot be accessed because the seat is stuck on top of them. Is there a way to just remove the cushion.

For the bolts that you cannot remove requires Torx Box wrenches.

Excellent solution thank you.
I've ordered a set; buying tools become my habit!

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.

Major,
No room to completely undo the bolt. Any further guidance please?

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.

Why won't the wrench fit? The wrench worked initially but space is now limited. Please see the linked video

Is the problem with the front bolts or the rear bolts?

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.
