Hatch Will Not Close, motor problem?
I've done a few searches but here goes.
My hatch motor is in the down position and it just hums. Also the hatch will not latch. The lock and key cylinder works fine. I can push the latch with a screwdriver and unlock it with the key. But I cannot push the deck lid down far enough for it to catch. I have tried pulling up on the motor but am reluctant to pry up on it a screwdriver. Any help would be awesome.

Also when I pull up on the motor it sounds like its binding down or something, just thought I'd put that in there.

take a look at the motor, bring the hatch down so you can see where it connects with the motor, there is a little plastic piece that the hatch "hook" taps to let the motor know to go down. Tap this little plastic piece down with a screwdriver, if the system is working the motor will come back up. If it doesn't then you may have a stripped nylon guide.

The last post has it correct. If the motor runs without moving up OR down then the gear nut is broken. A new gear nut is available from your dealer. I also stock them as well. While you're at it pull off the hatch surround plastic trim panel and check the unit visually. If the motor housing is broken it should be replaced. Also grab hold of the latch portion and see if you get movement. If it moves up/down but not side-to-side or front-back, then that clear plastic motor housing has broken where the 3 screws attach it ot the frame. If you get side-to-side or front-to-back movement, then the plastic guides in the tracks are bad. All are available from my web site. All the part numbers and instructions to repair the hatch pull-down unit are included in the Tech Article I wrote.

It will not move at all, its stuck.. It will move barely but thats under pressure from me wiggling it. I did see a small crack in the clear housing, would that cause the motor to run but no movement? I can't break it free.
