Auto rear hatch will not lock

bought it like this.
so fob buttons work, but not hatch.
but lock inside locks fail (elect. buttons)
driver and shotguns side both fail, lock sw?
ext, mirrors dead.
door looks in the service manual has 5 pages of schematics, is well advised to read that first
not scanning the PCM/BCM first is never good.
oK if the speed sensor on the car fails, doors will act up. (for sure if it see car moving and is not)
the radio receiver (fob) works mostly
Fuse MIR /LKS must not be blown door buttons fail
why not check all fuses, save work and not need books to fix it if a fuse blew.?(underhood box)
IP fuse PWR/LKS not blown
the BCM runs the 3 Door lock relays
possibles
Fuse MIR /LKS blown 3amps
this kill local door power to LF and RF door swithes dead. and Rear glass to. the relay board does not fail with fobs. is the key fact.
your post is not clear on all for doors.
or LF an RF door switches. but assumed both are dead, me.
so it is just blown fuse.
we always check fuse first. a 20 cent part.

Hi Danny.
I would go to O'reilly auto parts (not sure about other parts stores), they have a key fob checker, this will let you know if your fob is working or not. They also have replacement cases that you can put your circuit board in if your fob is bad. Hope this helps.

Found this wiring diagram for lift gate, if that is what we're talking about? Not only check the fuses, check fuse circuit for voltage. Use a testlite.

the switch is bad on the rear hatch cylinder

1) Your key fob could need a new battery.
2) Your fuses could need checking.

There are no keyless entry remote self-programming instructions for the 2008 Chevy Uplander. You must get an Automotive Locksmith to program the remote to your vehicle for you.
