Door jam switches die over time. I ended up as a temporary fix putting a folded up paper plate over my switch, duct taping it there, and the door would close and provide enough extra force that it would work. Then my alarm kept ****ing going off all the time because of the switch, and the lights started comming on again, I said **** it and went and bought 4 new switches at once, 40$ straight from dodge. (I work at a chevy dealership, cause I'm a retard and of course, no discounts on mopar) >=(
Actually speaking of which... I never got those damn switches in the car... they disapeared around the house somewhere, along with one of my clear corners.. So as of right now, I've got no switches in, and no dome lights at all unless i turn them on manually, and my alarm dosent really help with no door switches >_<
