Greg,

The issues you are referring to "the seat and steering wheel adjustment panel (door control module)" on front door panels is common problem.
For the seat control, pushing forward, the seat goes backwards, lowering the button, the seat rises, etc.

Remove the door panel and disconnect the plug to the control module. Try cleaning the connections/ crevices on the backside of the panel with compressed air/canned air, even some electrical contact cleaner. Do this carefully.
This may help. I've done this on my neighbors 98 e320 a few times, but eventually, these modules wear down (from my limited understanding of these modules and what mb techs have told me).
There is no "reset button" for these modules but I have also been told , when out of the seat, move the seat all the way forward and then in the opposite direction (to the back). This seems to reset the headrest setting.
I would also check the wiring and connections under the seat - wiring ages. Worst case scenario, pick n pull for a replacement door module.

You can also do a search for more info - plenty of past discussions on this know issue.

I have cleaned connectors and plugs , as i said above i have tried today different control panel and still problem exist , my concerns comes to door wire harness which came with the door from 2001 model year and my car is 97 , do you think it might be a problem ??

sorry

khomer2

Based on your vin# -
Part # 10
http://mb-teilekatalog.info/view_Sub...=82&subgrp=063

------
For a 2001 e320 - ( I just used a vin# off a 2001 e320 model to compare against yours) - part #50
- http://mb-teilekatalog.info/view_Sub...=82&subgrp=063

Based on a quick look, both years seem to take the same part #s albiet there are other part#s that differ.
You can verify this with the stealership on the additional part #50, 2001 part #s listed

Interesting ..... how about wiring harness ?? Can you check if they are same for all years ? If i remember right big black plug which comes from seat/steering panel to the floor was a bit different , had wings on the end and this one doesnt seems completly rectangle , also there is some extra plug on the door side which is useless for my car ??

Seems like they bit different or am i reading wrong ?

GregMb320

This harness comes from 1997 , why the part number is different ?

khomer2

What do you mean it is different?

This matches the part # to your vin#
Are you saying the new door you had installed came with a harness included in the front door replacement?

khomer2

Strange, Typically, as an example, when a door is replaced, it doesnt include all the other components that make up a complete door. It seems in your situation they assumed the harness (if it came with the replacement door) would match ONLY because the door itself is a correct replacement. Where is the harness to your original door?

GregMb320

Yes the door came with the harness, i didnt pay attention and didnt check the harness part numbers , i was sure they exactley the same
number you circle in red is correct part number for my car and i found it by google it , harness which came with replacement door has different part number soo this might be the problem with steering seat panel doesnt work
orygina harness went to the garbage .... (( shiiiiiiiit

khomer2

Only options is to swap the harness to the correct part # or look for the pin outs on the seat and steering plug and match to the existing harness you have in place.

GregMb320

Thank you soo much for your help , just ordered correct harness and it should come on friday as soon as i get it im gonna do a quick check without installing it . If it will work i ll be even more thankfull !
Btw how u use this website for parts numbers check ? I dont know german language ???

Goto the top right corner of the webpage where it shows the flags of different countries. Click on your desired country language.

Here is an update , i replaced my driver mirror and use the correct door harness , still no steering wheel adjustment at all ! Mirrors goes in different direction then i press the switch on center console !!! What should i doo ?????? Im out of ideas

khomer2

Greg,

Are you saying you have power going to the mirror and pressing the center console switch makes the power mirror move in the wrong direction?
Replaced the entire DS power mirror ?

Read thru this post to see if it can assist you.

GregMb320

Yes correct , they go into wrong direction ! And still no steering wheel column adjustment , meeen im gonna pull all my hair 😤😤😤

khomer2

Have you checked the fuses for the steering column adjustment ?

EDIT:

Here is another link you can read thru

GregMb320

No , where is it ? By the way where i can find correct for my model year mirror connection diagram ??

khomer2

Greg,

That's what the search button is for.

EDIT: another post

GregMb320

Cant find any diagram 😕😕 maybe i can try to disconnect the battery lets say for 30 minutes and see if mirrors adjustment go back to normal ?
