Hi,

My 1996 850 TDI does not illuminate the interior roof lights when the car is unlocked and the door is opened. They work fine on their own.

I’ve also noticed that the driver’s door button will work to lock the driver’s door, but won’t lock all doors. If you gently pull back the door handle with the driver’s door locked, then it will lock all the doors.

I’m therefore wondering if the two could be related, and I’m thinking there could be some kind of microswitch in the door which may be causing this, but I thought that I would check to see if anyone had any other ideas here first.

Thanks in advance,

Joe
