Toyota MR2 Message Board - View Single Post - Dome Light - Door Open

I swapped the dome light assembly from my parts car into my good car. I'm not sure if I am going to paint the thing black or not; I'll decide if the contrast looks as tacky once I swap the dark blue headliner for the light gray currently installed.

Well when I first installed it I wasn't getting any light so I proceeded to diagnose the problem. After much trouble that wasn't really necessary -when I checked the fuse it was good but then it blew when I put it back in, so the before and after voltage readings were confusing me - I figured out that the the little ball contact was corroded in the switch so I pulled it down and cleaned it as best I could with a nail file and dart (common tools, I know) because I couldn't find any emery cloth.

When I reinstalled it, in the ON position it worked but the door function does not. I manually bridged the connection for it and still didn't get anything so it's not the contact in this case. When I open my door with the keys in I still get that annoying buzzing sound so I think the door sensor is up and running.

Any ideas on my next diagnosis step?
