I had a funny issue with the doors locking and unlocking. Nothing to do with your issue I'm sure.

My trannie is a motorhome. One night I was parked up with several other MH and every now and again the horn would go off and the doors would unlock. Then they would lock again all by themselves. Dark rainy night, strangers parked up all around me. This went on for a couple of hours. Couldn't work out what was happening. Even entertained the idea that someone close was remotely fooling with my doors.

Now, I take a dog with me and she was up on the bed running backwards and forwards a bit agitated with what was going on. She only weighs 2kg.

Anyway, finally noticed every time she went down to the bottom of the bed the door locked/unlocked. Whats going on ? Hows she doing that ?

Then, I, remembered. The spare key was in a folder under the bed. Dogs weight was enough to activate the button.

Does your light tell you which door it thinks is open

Possibly worn/broken wiring in the rear door loom, as that's a common failing point

[vince pinneri]

it shows both front doors are open on the dash
doesnt show the rear door open on the dash screen when i open it or side door either
have any idea what can be causing this . this is driving me mad i tried to remove the driver side door lock i could not get the barrel out l tried turning the key clock wise and push the in screwdriver in the whole cant feel anything pushing in tried anti clock wise same thing been on it for for awhile just cant get it to release looked on utube on how its done wont work for me what is happening . i just want to take out and give it a good clean and see if everything is ok
need help

I would still check the loom going to the rear door, at the point where it flexes when the door is opened

As with most electrical problems, the fault can sometimes be nowhere near where you think it should be
