Multiple Electrical

[bix49]

I have a 2002 Montana. Recently several electrical components went out at the same time. The cruise control, rear shock air pump.. The interior lights don't come on when the door opens but they do work with the switch on the overhead console. The rear vent windows. The self locking feature when you push the lock switch as you exit the vehicle but you can lock and unlock the van with the fob. Powered sliding door. There may be something else but this is all I can think of now. Does anybody have any idea about what could be affecting all the things. I'd appreciate any thoughts on this situation. Thanks

You are sure all of this stopped working at the same time?
have you checked the fuses for the various circuits?
