Sliding doors, radio and dimmer

My 05 Chrysler T&C sliding doors do not lock by button or key fob, I have to use my hand. Also, I see a message on info center saying sliding door is open on passenger side, but the door is shut. The dimmer is not working right, when I turn up the cabin ligts come on, so I have to keep it on low.
The radio is working fine, but I can not lock on station, it just keeps searching, and when it stops on a station no sound comes, it is like the stations are dead!
Thanks for the help.
