Thread: Random door open signal - related to window not auto up

Hi all

Wondering if there's anyone out there that has had a similar experience to this and what they did to resolve it:
The passenger side rear door started not locking and unlocking randomly. Fine, I know what that is, I'll replace the door latch with a new one. Problem solved for a couple of months.
New problem now, the door is shut and doesn't show it on the dash. Now the car can't lock because it sees the door as being open. Coupled with that is it is reasonably random in nature and also that rear door will not auto up as it normally should. Also the car cannot raise or lower suspension as it 'sees' that the door is ajar (when it is definitely closed). When the problem disappears and the doors can be locked, lo and behold, the window also behaves as it should (as per the suspension control as well). I'm inclined to blame the controller that sits on the inside of the door card rather than the new door latch. Has anyone had to replace those door controllers before?

I do not have the problem like this but based on my experience with other cases like this, you might try those solutions:

1- Clean and Dry. Many times people getting this symptom from other cars they just pull out the driver side panel and other door panels to check and clean and dry the door switches and their contact pins (start from the master switch panel to the rear one). Reason being rain/water drops/coffee drops/dust/moisture going under and created a bad contact inside.

2- If Clean and Dry do not work, then do Scan. Use a professional and updated firmware scanner to give it a deep scan when the issue happens, it would likely be able to check out what is the cause then you start from there.

3- If in case the Scan does not work (means it could not show you what is the root cause of the issue), then generally speaking your master switch panel is the first one needs to do the crossed checks with a working condition unit, then combine tests with a working unit for the rear switch panel too.

if those solutions not work for you, then you should bring it to a LR specialist for a deeper inspection.

Hope you can get it sorted.
