DIY: Replacing Door Sub-Harness
Hello Folks!
Special thanks to -jon- from mdxers.org for finding the solution!!
This is a small DIY on how to replace the Driver door sub-harness and what problems it can give if its damaged:
Symptom's (Incredible list for such a small cable):
1.- Door locks wont work
2.- DPMS wont work
3.- Rear view mirrors wont adjust or auto-tilt
4.- Power Tailgate wont open either by the FOB or Button in door
5.- Gas cap wont open
6.- Alarm wont engage
7.- Windows wont work
8.- Sunroof wont work
That is about all the problems that little bastard gave me.
Now how do we replace this little cable...
Models: MDX 2007-2009 (All Trims)
First of all you will need:
1.- Small flat screwdriver
2.- Flat screwdriver
3.- Part No: 32757-STX-A00
Total time to replace: Less than 5 minutes
Experience needed: None, Super Easy to Replace
Box the part comes in
So much problems for such little cable
Steps:
1.- First of all you will need to remove the sub-harness from the door, This part comes as a whole with the grommet so you will have to pop the grommet off and remove the cable from the door.
2.- Now you will have to remove the fuse plastic cover completely (This just pops in) to get to the inside connections..
First remove the door side molding (A) then remove the lower door guard (B) this just pops out with little force, Finally remove the fuse box cover (C) by popping it off too! It will have a small plastic screw attached in the back you can just move aside the cover no need to remove it completely.
3.- You only need to make enough room to see the sub harness connections in the fuse box
The cable will have a small retainer plastic tab connected to the fuse box, You can break this as the new cable comes with it.
To install the cable just use the connectors as guide through the chassis hole, This is basically the hardest part because space is tight.. What I did is put my fingers between the fuse box and chassis and pull one connector to guide the whole cable.. Once this is done just reverse procedure! and you are DONE!
This little cable made my whole "New MDX Experience" a nightmare and I cant believe this problem isn't wide-spread.
Now to dissect the old cable and see what went wrong
Hope it helps anyone, Any questions feel free to Ask.

And here I thought It was going to take me an hour to diagnose each cable with the voltmeter.
The problem was right at the door plug....
Several cables just broke and some were starting to peel.
Seems like the cable is under heavy stress... Again why the hell this problem isn't wide spread?

You're welcome. I hope this helps anyone with the same issues.
I cant believe the joy it is to being able to open my gas cap with the button hahahahaha. It was embarrassing to crawl through the rear seats into the trunk to release the gas cap manually every fill up...
