Question about 2003 Chevrolet Suburban
Rear doors and tailgate would not unlock. Tried reseating the 20 amp fuse in the driver side dash panel and they worked again for a few days. They have gone out again today. The fuse is not blown. Door locks function the same with the fuse (20 amp) removed.
You need to replace the Unlock Relay, it should be in the fuse panel on the passanger side.

Pull drivers rear door panel off
1. Remove door lock solenoid and plug it into another door to see if it works
2. If you can reach inside the door to the final mechanism that everything pushes on, push it yourself to see if it works
3. Also look on side of door for possible child saftey lock switch

Check the fuses first. If that dont work take the door apart the wiers have problably lost the connection due to kids and chocolate.
Gotta love them tho.

your issue involves the master control switch panel on the drivers side and or the passenger side as well some how the contact inside the switch assembly has either shorted out or no longer makes contact for the unlock side of the circuit. replace the drivers side panel switchs it's either a series of switc hs or mostimes one sigle board of switchs. you are better off going to an auto parts store rather than a GM dealership this will save you quite a bit on cash on the parts. now as to the rear tailgate. if it is electronic controled and there is an issue with the master switch you can,t manually unlock it because of a safty issue built in the system. you can manually unlock the passenger compartment doors for thew same reasons of safety but doesn't apply to the tailgate. just replace the parts and this will take care of the problem

Look on the door panel for small plastic covers. There should be one or two at the door handle and maybe another closer toward the door hinge. Also, around the perimeter of the door panel, there are some plastic inserts. They are ribbed and are just pressed into holes on the metal door frame. You just pull on the door panel in these areas to get the plastic inserts out. There might be as many as 3-4 at the bottom and a couple on the sides. Where the panel contacts the window, it just slips up. None of this should take too much force, so if you are having to pull really hard and the panel is moving, there must be another screw or something is stuck. Careful not to break your panel. Once inside, see if there is a linkage disconnected. From what you have described, it does sound like something mechanically wrong.
