Hi there. I know this video was a few years back but hoping you can remember. I'm just about to tackle this exact fault in the next few days. Will the dead drivers door switches spring into life as soon as the faulty rear door module is unplugged? Or not until the new one is plugged in? Wondering if the Lin bus is wanting all modules connected to start working. Thanks in advance.
Hi Brian Yes I’m pretty sure when you disconnect the faulty rear door module, the Lin bus stops being pulled down and the front door should work. Hope this helps Charlie
Hi buddy, i have a issue with my window switch, memory seat buttons, and also the driver side seat buttons. The driver side seat buttons only moves a notch were it should be a continuous movement when any button is pressed and held to the desired position. The diver side window switch only work for the drivers mirror. However when i hit the driver window switch or open the door all the functions work. Do you think its a module issue? At night the window switch lights dont light up unless i smack the side it open the door.. lights on all works well, light off and above issue present.
Hi With your issue changing when the door is open, first place I would look is the door aperture wiring loom. If you have a broken wire in that loom it Will give you those symptoms. Hope this helps
@brownsautomotive7102 thanks.. when i posted that message, the next day i took the door card off, thinking it will be the door lock latch actuator based on another video i saw. But i also remember you saying if the door card is off just check the plugs and the door module for any dirt etc.. and boom... the plug was loose (left side). All sorted now.
Very useful thank you. My memory seat buttons are not working on the passenger door, door lock/unlock buttons are ok. Does that switch pack connect to the door control unit as well? It’s diagnosed through the seat control unit and there are errors relating to the individual buttons. Driver side is fine.
Hi Mark The easiest way to be 100% is to take the door card off and follow the wires from the seat switch pack and see if they run to the door module. Sometimes the switch packs are interchangeable so you could try the drivers side in the passenger. Hope this helps
Another excellent video, i had exactly the same issue, i did replace the front module with a used one but still no luck checked the rear door module, and it wasn't corroded but after spraying switch cleaner on the terminals all started working again, the only thing that still does not work is the electric folding mirrors, swapped the front door module back to the original and the front window was starting and stopping i could feel the relays in the module clicking on and off, so i fitted back the used replacement module i got and all was fine again, module has exactly the same numbers on it, just mirrors dont fold - have you any suggestions, or do you think the used module isn't coded for folding mirrors?
Hi Yes you can do that with a good diagnostic tool or you can do it manually. With each window hold the button down until the window reaches the lower stop, hold for a second then do the same going up. If successful the one touch opening will work. Hope this helps Charlie
Great video! Well done for uploading. So to confirm, does the LAN signal run independently on each side of the vehicle (Front and rear each side) Or round all 4 windows? Or can a Front only affect a rear or vice versa on the same side? Thankyou in advance 👍
Thanks for the feedback 👍 From my memory the LAN signal runs on each side so if a front doesn’t work check the rear the same side. On the vehicle in the video the passenger side was working fine. Hope this helps Charlie
Hi By testing the system and knowing how the LIN bus system works, corrupted signal was still present with the front switch removed meaning it has to be further back on the RH Lin bus circuit. Hope this helps
Yay you uploaded it’s going to help the more you upload
Will replacing the module fix the window not rolling up? Or does the whole panel thing stop working if the module is bad?

You said final thing to do is the anti trap and window programming what does that mean .. how do you do that ? Diagnostic tool ??

How did you notice problem in rear Rh door module?
Hi
By testing the system and knowing how the LIN bus system works, corrupted signal was still present with the front switch removed meaning it has to be further back on the RH Lin bus circuit.
Hope this helps
@@brownsgarageltd In your video you not shown that procedure that's why I confused.
Great video
Thank you 😊
