Door trigger

You guys know that "thing" that is pushed in when the doors are closed at pops out when it's open which will turn on the light in the car (I'm assuming it's called the door trigger)? Well, my driver side is fine but when my passenger side door is open, the light never comes on. I have to push the trigger in and let it out before the bulb comes on. Anyone have any easy fixes for this? At first my driver side wouldn't come on either but me and my buddy took of the trigger once and I'm thinking it kinda loosened something which made it work fine now. I tried unscrewing the passenger side today too but those stupid screws are so tight and it seemed as if the screw might start stripping so I stopped. Anyways, any help would be much appreciated. Thanks!

usually the best thing for em is a electronics-safe spray-penetrating oil, like BreakAway. Any self respecting mechanic will tell you, never use WD-40!

I've never heard of that stuff before....do they sell that stuff at like Kragen or AutoZone?

I always bought it at a local auto parts store called Orleans Auto, in Orleans, MA, but i think you can order it at NAPA, dunno bout the Zone, but its worth every penny. PB Blaster is almost as good if you can find it easier, but it leaves nasty orange stains if the drips arent cleaned up. Break Away is made by Cyclo(spelling?), its a well known brand, you should be able to atleast find it online.
