I have a friend who had a Jeep with power lock issues.We ended up replacing all the power lock actuators,one at a time over a period of two years.Put one in, all is good, another one dies.make sure you have SWITCHING power and ground, not just power.If you do, plan on an actuator. The power locks usually made a squeal or chirping noise before they died...

I have power to the door lock switches on the drivers door but the locks do not work nor does the back hatch or the switch at the back hatch that controls all the locks in the vehicle. Do the locks g

Power Door Locks Circuit Description
The power door lock system incorporates door lock switches on both front doors and on the RH D-pillar, door lock motors in all passenger doors and in the RR cargo door, a door lock relay and a door lock control module.
Power for the door lock switches and the door lock control module is supplied from the CIG LTR fuse 13 through CKT 640 (ORN). Power for the door lock relay is supplied from the PWR ACCY circuit breaker through CKT 540 (ORN). Ground for the door lock relay is supplied from G202 through CKT 150 (BLK) and ground for the door lock control module is supplied from G400 through CKT 150 (BLK).
The door lock motors are reversible and both sides are connected to the normally closed contacts of the door lock relay. Those contacts of the relay are connected to G202. When any of the door lock switches are placed in the lock position, voltage is supplied through CKT 195 (LT BLU) to the relay lock coil. Since the other side of the lock coil is connected to ground, the coil is energized and it pulls the lock contacts closed. Voltage is then supplied through CKT 295 (GRY) to all the door lock motors and the doors lock. The unlock function operates in much the same manner except that when any of the switches are placed in the unlock position, voltage is supplied through CKT 194 (WHT) to the unlock coil of the relay and CKT 294 (TAN) supplies voltage to the apposite side of the door lock motor and the doors unlock.
Door Lock Control Module Description
The door lock control module is used on vehicles equipped with cargo doors. The purpose of the module is to lock the cargo doors after a lock cycle has been commanded from any of the door lock switches with the cargo doors open. When the RH cargo door is open, the module receives a ground signal from the closed contacts of the rear door jamb switch on CKT 1897 (ORN/BLK) to G400. When a lock command is received, the module retains this input until it receives an open input from the rear door jamb switch. Then the module sends a lock command through CKT 194 (WHT) to the door lock relay and the doors lock.
Rear Cargo Doors Description
The power door lock motor will not operate unless the rear cargo doors are fully closed. The power door lock motor is in the right cargo door. The contactors are on the rear cargo door opening on the body and on the right cargo door.

Do the door lock switches on the doors work both ways? If not, then check to see if you have different relays for the lock and unlock functions, like my jeep does. You may have a burnt relay or possibly a bad / stuck switch. My relays are not in the fuseblock, but in a separate relay center under the glovebox, so you should check your owners manual for the relay location. The only way to lock the back hatch would be by key, but you'll have to relock it everytime you use the remote until you can find the problem. You should also check out your ground wire for the lock circuit. Happy hunting!!

Did these doors quit at the same time or over a period. It seems that the actuators for the locks have gone bad. With the mentioned doors, that's a lot weight for the actuators to unlock and pop open. With the remotes and console not working , that's more reason to think the actuators are the problem.
