2009 Acura MDX.
Power mirror doesn’t work. Driver door back lights doesn’t work. Window switches doesn’t work. Lock unlock button doesn’t work. Memory seat doesn’t work. fuel door doesn’t open. Rear liftgate doesn’t open.
I took it to a mechanic shop. They told me the door switch was bad. They need to replace that first. If that doesn’t work they will replace the door module. If that doesn’t work they will replace the body control module. I told them it’s a ground related issue. Because there are too many things that are being affected which are unrelated. Did you want to listen to me so I started looking into it myself.
All of these issues or caused by a single grahams place or may be a broken wire. I simply did a overlay for the ground circuit and that solved the issue.

I had the same problem. I replaced the electrical sub-harness that connects the driver side door to the harness by the fuse box next to the parking brake under the dash. Post pandemic, Acura had run out of this sub-harness. I waited one year for it to be in stock again. It cost me $80 and took less than an hour to install. There are videos on KZfaq that demonstrate the installation. Tip: The opening between the door jamb and the cabin is not easy to see. You have to route it through the opening with your fingers. When removing the old sub-harness, I tied a long shoestring to one end. When I had removed the sub-harness by pulling it through, I left the shoestring in the opening of the door jamb…one end in the cabin by the fuse box, the other end hanging in the opening in the door jamb. When I was ready to install the new sub-harness, I tied the shoestring to one end and pulled to through the opening…with a lot of feeling around with my fingers. It made it easier to do.

@@reynacastilleja1617 kzfaq.info/get/bejne/Zs13idRzq7Ddp2Q.htmlsi=NcKh_dbAJ5_CPZiJ I tied a shoestring on the part of the old subharness that I pulled through the door jamb opening above the fuse box on the left side of the driver’s footwell. This opening is not easy to see and removing the old harness and installing the new harness requires a lot of feeling around to guide it through the small opening. Once the old harness is out, I retie the shoestring to the new harness and pull it through the hole using the shoestring. It all is done by looking at the external door jamb opening and feeling for the opening above the fuse box in the cabin. Best of luck.

Good job I have same problem but my front windows work but back windows and mirrors lift gate don't. Some say it is the door to foot panel wires but mine look good. I am going to try the same way you did. Thank you

My guess is the signal goes from switches to door control module, then the body controller. Maybe you have a bad door control module. If you can open and close the windows using the key inserted to driver door. Then you can rule out some wiring. Basically twist the key like you are locking/unlocking door then just hold it there.

Def door to foot panel

04 Acura MDX Car thinks door is open when closed. Replaced jamb switch, still doing it, but dome lights dim and anti theft engages. Door open is still displaying and light bulb on driver panel is on. If I remove the bulb dome lights come on and anti theft will NOT engage. Ideas?
