I have a 1998 blazer. The back hatch window lock keeps acting as if wants to open. There is a noise the whole time you drive unless you hit the button on the dash to open the window.

get new dash switch

well if you wanna save money you can install your own button to open the back hatch and unhook the old one electrical can be tricky and expensive

I had the same problem with my 2001 Blazer. Just remove the panel by the screws located on the side of the tailgate, the problem was a bad actuator which pulls the lever to open the glass hatch. Once you take off the panel, remove the metal shield on the tailgate and the actuator will be mounted on the back of it. There are several ways to open the hatch on blazers and jimmys. You can try to release by inserting a small screwdriver and pushing left using the entry hole in the rear hatch deck just below the plastic trim in the center. This works ok unless the latch is out of alignment. The quicker way to release the window lock is to pull the center of the plastic trim (where it rises) toward the inside of the car and break the plastic trim attachment. Remember first to remove the hatch handle.By pulling away from the window, you can then insert a finger between the two walls of the lock assembly and push down. The window will open immediately. Ignore the broken trim attachment as there is plenty of support for the top of the door trim piece. Unbolt the 9/32 panel screws and the two phillips head side screws and the panel will come off. Careful of the rods clipped to the panel. They come off easily as does the hatch door activator. Rather than have to buy an actuator because the blue piece of plastic broke, replacements are available at online auto supply stores. Remember to make sure that the lever of the actuator hits the window release mechanism squarly. A little bending with pliers will align these two pieces so they strike evenly.

1998 Blazer. hatch window lock keeps making a noise. like its trying to unlatch.i open window it stops.

The actuator is not engaging the lock mechanism.You need to open it manually from inside the truck There is an access hole on the rear end gate pad where the material meets the plastic directly in the center you can feel a soft spot in the fabric backing with your finger.use an awl or ice pick to poke thru the hole and feel for the lock arm and pop it open then unscrew the end gate pad and inspect lock Good luck

he small plastic clip that holds the rod on most likely broke or fell off. take off the int panel and look in with a light while hitting the button, the problem will be obvious......

had same problem was linkage in gate was messed up.had to remove plastic panel from inside and fix linkage.i could here actuater working when i used key hope this helps

you are going to have to replace the lock buttom actuator motor.

Hi: Under your hood in the power distribution box is a 3A fuse, if blow your door locks and rear wiper motor won't work, replace fuse. To manually open door ... take a pick or fine longer screw driver and insert it through the carpet liner on the interior back door (center, top of carpet you will find a indent under the carpet.) move pick to release the door latch mechanism.

You need to climb in the back and remove the plastic panel from the hatch to access the lock. There may be a small access door over the locking mechanism to help you avoid removing the whole thing. Could be dirty and sticky and fixable with a bit of graphite lube.
