Hatch pulldown motor

Had a weird problem with my hatch tonight. I was just heading out of town on business when I loaded the car and closed the hatch. When I got in, I could hear a kind of "grr grr gr gr grrrrrr" noise. The hatch closed, but it was like the motor wouldn't shut off. Not the sound of a relay clicking or really of a motor running.

Had to leave on business, so I just headed out. Ammeter looked fine and no probs on a 200 mile ride. When I got where I was going it had stopped.

Any ideas?
Thanks

i had this happen to me a while back.

mounting tabs for the plastic pulldown motor assembly had cracked. this assembly houses the motor and gears. the broken mounting tabs caused the entire assembly to be mis-aligned. i tried using plastic solvent to repair the mounting tabs, but they would break again in a few weeks. a replacement from GM was $34.

Same thing happend to me. When I bought the car the moron just took out the fuse and none of the power options worked. After fixing the cig lighter and plugging in fuses I found that it wouldn't shut off so i just unplugged the motor and use it like a normal trunk.

Thanks, guys.

Problem hasn't repeated, but Stephen's suggestion about the tabs makes sense. I'll check that out.

The plastic motor mount is cracked and broken. It can be repaired. If it has just cracked you can epoxy a sheet of aluminum to it and wrap the aluminum around the sides of the plastic. If completely broken you need to epoxy a piece of steel in the broken out section, drill and re-tap. I've repaired them both ways. It's just easier to do it if it hasn't completely broken away yet. Good luck, Lon.
