the interior light some times go off when doors shut but most the time it stays on and i have bin round and gave
all the doors/boots and good slam.
Is it a sensor fault?
Sounds like the micro switch inside the door lock to me. I had this 2 years ago and fixed it by cleaning the microswitch. There was a thread with pics on somewhere as this is a common issue. HAve a look in the FAQs.
my dog knocks the rear interior light on with his head on a regular basis, so many times ive come out in the morning to find it on. probably shouldnt hoon it so much with a 40kg german shepherd in the boot lol
