Hi there I just recently purchased a Chevy express 2500 work van. (love it).
I have two quick questions.
1. does/should the rear door lock open by using the keyless remote?
mine never opens when i press the remote. all the other doors open but not the rear door.
Is this the way they were made or is something not working right. It's getting kinda annoying. I'm a plumber and am back and over to my van all day long, allot of the time with tools boxes etc.... i would love it if that door would open on the remote.

Another quick question there are two wires hanging loose under my passengers side seat with a little wire harness on them does anyone know what these are for????

Thanks guys
nice to be part of this site

 

I have 06 Cargo with keyless and all of the doors are opening with remote. Check and see if your actuator is working. Mine just quit on side door and Dealer wants $150 for it.
Check over at this site (Mods please remove link if it is against site rules)
Door Lock Actuator

 

+1 on the actuator... Also Cargo Door has a separate fuse #5 (10amp) and relay #27 in the body fuse block in case you have not checked that yet.
