door locks
 

i have a 2008 gmc 2500hd and not able to unlock doors on driver control but able to do so on passenger side . I took switch apart it is good , jump wires and still not able to unlock , any clues were relay box or controls are located and even a scematic.

I had the same problem with mine... turned out, it was the switch.

There is a lot of contacts in one switch.. Are you sure you jumpered the right wires?
