E46 Drivers Door Problem

[AndrewO]

Had this problem a couple of times since I've owned the car over the last 6mths but yesterday with the cold weather things have got alot worse.

Basically the car occasionally thinks the drivers door is open when its not. This causes loads of problems such as the alarm going off, window going up and down 5mm and interior lights constantly on. Yesterday this problem was more or less constant. I'd lock the car with the key (no alarm) and the interior lights would be on within 5minutes. The pain is when the car is then opened to turn them off the window goes all the way down.

After trying lots of things finally had to disconnect the battery. Any suggestions ? Garages are all closed up now until the 4th Jan.

Have you checked the courtesy light switch to see iif it's sticking? This time of year etc...

I'm no expert, just a thought, easy to check.

Just squirted a load of WD40 into the latch but no change. Booked into the local garage for the 4th Jan to swap out the door lock.

What do you think that will achieve?
