I hv problem with the front interior lamp.
It works only with door open.

I need to know:
1) There are 4 wires connected to this lamp socket.
Where are these pins(TK, 30, 31, 30) connected to ?
I know pin30 is connected to the +12V and not sure
the others.
2) Does this light goes off with graduately dim then off
completely or
goes off after certain delay time ~6 second after the
door close ?

Thank you.
