You've likely stripped the plastic gear. I just replaced mine. $6 part new or $1 at the junk yard. Takes 10 mins.

Plenty on e-Bay. Sorry was $9 plus shipping. I had one in my hands at the junk yard yesterday but didn't have a torx driver to remove it.

Re: rear hatch motor does not stop running
actually you should be able to get that plastic gear from any cadillac with a electric trunk pull down, the plastic parts and motor are the same, i grabbed 4 on my last yard visit lol

I think what happens is the struts get lazy after time and don't lift the hatch off the mechanism and it won't go all the way up. The motor keeps running trying to push the hatch up and ends up grinding the teeth off the gear.

That's probably a good idea to have an extra 1 or 4 on hand!
