2008 Chevy Express van dome light does not come on when any of the doors are opened. Will turn on with the override switch turned clockwise. What could cause this?

You need to replace the handle itself. The inside of the handle where the metal cable fitting attaches causes too much strain on the plastic and the molded groove breaks. Ford has the same problem. I don't know why these car man. dont just go back to all metal exterior handles. If you have time you can probably fix it with epoxy and washers, but the fastest way is to get one aftermarket or from a junkyard. Hope this answers your question.
Please remember to rate this fix.

Did you check the dome override button? It shoiuld not be pressed in, otherwise the lights won't come on with the door or the dimmer slide switch moved all the way to the top.

You have to remove the upper applique to remove the tail lamp, it is the trim panel above the lamp. I think it is held in place by two nuts/bolts but not sure. You have to have the rear doors open to remove it
