Rear hatch issues

[builds4christ]

Hey all. My rear auto door is doing something weird.

It's had the chafing wiring issue addressed already.

But what it does is on the way down it begins to make a sound like skipping gears and gives up and goes back up.

If you put pressure on it with your had, gently pushing downward, it closes ok.

Anyone know what would cause this? Weak motor?

I replaced the struts and I wonder if they're too strong lol. Dang Amazon aftermarket.

There is some clutch mechanism on the motor drive gear. Sounds like your motor is strong enough, but the clutch maybe slipping.
I haven't heard of anyone fixing one yet, but there's a screenshot from here..

In that video, the clutch wasn't his issue, so he doesn't dissasemble any further than this on the liftgate motor.
He also shows a clockspring in the video, but it sounds like it's a helper spring for opening the liftgate.

Thanks for the leads brother!

I'm thinking I may just need to buy another unit. I've seen that clutch for an exorbitant amount of money.

But it's weird, it's not encountering any obstacles, and it's on the way down. Hmmm, on second thought, maybe something is causing it to bind that I can't see. I'm going to dig into it at work on my lunch.

I agree, it does seem like a replacement motor would be easier/faster than messing with the unit.
Only resistance coming down would be the struts I would think..
