My interior light will not illuminate when you open the doors. It will work if you move the overhead switch manually to activate it. I have tested all the switches using a continuity tester and all switches work, so the problem is not with a switch. I have 12v power to the switch on the drivers door, but no power on the lead at the passengers door switch. This is a used car where the factory radio/keyless entry system has been removed and replaced with a aftermarket radio (using a conversion wiring kit which came with the radio)

Is the door light system tied in to the factory radio system and this is the reason that it no longer works? I am not a mechanic but have looked at a wiring diagram and it looks to me like this is a possibility. Does anyone know for sure before I keep waisting more time trying to fix something which is impossible to fix?

 

if you installed an aftermarket radio most likely that is the problem. There should be little green plugs still hanging in your dash cluster behind the radio. there should be 2 little puke green wires plugged into one of those plugs one has red dashes and the other i think is just flat puke green. Tap them together.

Yes. In '96-98 Civics, the dome light and the keyless entry function are tied into the factory head unit.

 

OK Thanks guys...........
