how to remove 2003 ml320 door panel
I just removed my interior driver side panel on my 2007 GL450. Here are some pictures to show how it looks like. There are clips and be really careful on the flat wire. If you accidentally ripped it and i thought it would cost hundreds of dollars. But i was surprised the replacement is really cheap. You can order new ones from your local Mercedes wholesale parts department and they sometime stock these. The part number for the major flat wire is A164-540-56-06 and they call it a coding plug and the cost is $39.60. The second flat wire that runs from the trunk control to the module is A164-540-59-06 and it costs less than $20.00. I ordered it from your local Mercedes wholesale parts department and replaced it in my interior door.
Couple of things for you to remember when taking the door panel off. There is a chrome that you have to pop off and is held with clips. Once you pop it off, there are 2 torx bolts that you have to use the torx screw driver to take out. Next is another bolt where your lock and unlock switch reside. You have to first pop off the buttons from the switch. Once you pop them off, you have to carefully use a small screwdriver to pop off the switches. Once you pop them off, there is a torx screw hidden behind those lock/unlock switches. Before we unscrew the torx bolt, please reach behind the panel and unhook the flat wires. I made a mistake of unscrewing the last bolt and the whole panel dropped to the floor ripping the flat wire off the connection.
Hope this helps. My pictures attached.
Thanks
William
