Car has been garaged over the winter and has developed a fault with the interior courtesy lamps, basically the two lamps located in the drivers and passengers footwell , which are supposed to switch off 10 seconds or so after the car is locked, are staying on all the time and consequently have drained the battery. I have removed the bulbs which solves the battery drain problem for the moment but would like to have the problem fixed properly. Does anyone have any ideas why the lamps are staying on and how i go about fixing things.

 

at an edjicated guess i would say that they will be controlled by something like a relay somewhere. find a wiring diagram and have a look. If it is a relay give it a tap see if that works if not replace it, i could be completely wrong but being an electrician i am pretty confident
