2003 e320 wagon (210 chassis NOT a 211))
Open door sensor(s)?
I have a theory...
I think that several of the minor annoyance problems with my wagon may be due to just one "door open" sensor being bad.
Is there such a thing? If it were faulty on one door (oh, say the driver's side rear door, just as a random example
) what would you expect to go wrong?
Here are the things I think are related...
1) The rear driver's side door won't lock/unlock with the rest when central locking is activated. It has to be manually locked/unlocked.
2) When the car is locked remotely (using key FOB) the lights don't flash as they are supposed to (although they do flash when unlocking)
3) If I lock remotely, without locking the left rear door manually, then open said door from the outside, the alarm (99% of the time) does not go off. The alarm has only gone off twice since I've owned the car. Both times when it did go off, I cleared it, and then re-locked the doors, and strangely, the lights flashed as they are supposed to upon locking. I then unlocked and re-locked and they went back to not flashing & the alarm not working. (this intermittency is the main symptom which makes me think a switch/sensor of some sort may be faulty)
4) The key FOB panic button does not do anything.
5) The IR window up/down control feature of the key FOB does not work.
6) The automatic interior light switch (the middle left one of the four light switches) which is supposed to activate/deactivate the lights when opening or closing a door, instead just works to turn on all lights regardless of whether there is a door open. (This makes me think that the system thinks one door is always open).
I think I've listed everything. There may be some other "features" misbehaving that are also related to this, that I haven't noticed yet.
Please let me know your thoughts on whether all or some (& which) of the above might be related, and if so, related to the door open sensor or something else.... and if it's something I can fix my self!
Thanks
