Ok this has me stumped ever since the other night I have not been able to make my interior light turn off when I close all the doors. When all doors are closed the light dims and flickers.

So far I have checked the following:
Removed and checked all fuses
Removed and checked all pressure switches on the doors
Made sure my battery terminals etc were all on tight
Turned the car on to see if it made any difference
Tried in all key positions
Checked both lights
Turned the dash light dimmer down

I am f'd if I know but it's doing my head in.. Things I have done lately have included fitting a pulsar alternator messed a little with dual battery system. I have removed the dual battery to see if it affected it and no. I have also removed the alternator plug and no avail.

The only thing that I can think of that may have had some effect it that I plugged a phone charger into the cig socket and heard a little zap I guess you'd say and the little green light around the lighter died. (Would also appreciate info to fix this)

I personally think something is shorting out or a relay is f'd but don't know where the relay for the int. lights is located...

Please feel free to mention anything I wont get offended because I am trumped on this..
