How to open back hatch back when power lock controls broke

SOURCE: HATCH BACK WON'T OPEN

You may want to just remove fuze #28 under the hood...for about 30 seconds...reboots the bcm and it corrected my Aztek's ills.

Turn on the rear window wiper . Try to get the wiper arm off the glass. There is a switch that will not let the window operate if the wiper is on the glass.

There is not a seperate relay or fuse for that particular lock. One fuse runs all of the locks. The problem probably is in the wiring where it hinges from the body of the cat to the trunk lid. You will find a plastic wire loom going along one of the hinges for the trunk lid, you will have to open up the loom and check for a broken wire where the wire bend the most. Some times just shaking or moving the wire harness will make the lock work.

You have to crawl in the back remove the panels and find the actuator(s), when you find them check for any linkages the may have fallen off. Gm uses little clips that get brittle and break. if it is a clip reinstall rod with a new clip or reinstal rod and secure with mechanics wire.

If the actuator is broken you can hook up a volt meter to the pin outs and test for power by hitting the door lock unlock button. If there's power then chamces are that the actuator is faulty. if theres no power check ground connections fuses relays and re test. good luck
