Help with my interior lights

I have had my 166 for 3 weeks & the front interior light has got me puzzled.

When i close the door the light comes on & when i open the door it goes off.
The back interior lights work ok.

any thoughts ppl

Closing the door puts the light on for a while, leave it and it should go off. If you open the door before the timer has finished it'll go straight off.

when the door is open the light will not come on at all & when i shut the door they stay on all the time.

Functional description
The supply for all the courtesy lights arrives directly from the battery via the line for maxifuse CENTR of B5 and fuse F17 of junction unit B1 .

The interior lights G10 (front) and G25 and G26 (rear) are switched on - depending on the positions of their internal switch - by an earth signal which is direct (permanently on) or timed.

However, the lights on the doors (front left G51 , front right G52 , rear left G55 and rear right G56 ) only ever come on for a timed period.

The timed period is managed by the special courtesy lights relay J42 , supplied directly by the battery via the line for maxifuse CENTR of B5 and protected by fuse F17 of junction unit B1 .

The timed period is operated by the instrument panel E50 , which sends the signal (from pin 11 of connector B to pin 85 of timer J42 ) as soon as at leas one of the doors is opened via switches N50A , N51B , N55 and N56 , connected to pins 14, 15, 16 and 17 of connector B of E50 , respectively.

The timing is interrupted when the ignition 'on' signal is received, which reaches the instrument E50 from the ignition-operated line (INT/A) of the panel - pin 15 of connector A of E50 - through fuse F1 of junction unit B1 .

Timing starts from the beginning again if the doors are unlocked via the safety knob: these signals reach the instrument E50 - to pin 12 of connector B - through the switches on the knobs, located in N50A and N51A .

The timed period is also activated when the door locks are released using the key or the remote control.

J42 is located beneath the front tunnel.

cheers for the info.

I'll have a good look at it this weekend when i get time
