Gang,<br><br>
You all were so great at my last question, I've got another one for
you.<br><br>
Anyone know how these power hatch opener & closers work? A
neighbor said she<br>
went to pick something up and told the person putting it in the back of
her SUV<br>
NOT to close the hatch, she'd get it. But the person grabbed the
hatch and pulled<br>
it down. Ever since it has been intermittant.<br><br>
I went looking for any info I could find on how they work and I couldn't
find <br>
anything. I was thinking there were linear actuactors. But if
that were the case<br>
I don't think they should have been able to close the hatch
manually. I though<br>
a linear actuactor was basically a long bolt (all thread) attached to a
motor with a<br>
nut that was attached to the item you wanted to more. If that's the
case, then<br>
you shouldn't be able to force the hatch closed as the nut would not
slide on the <br>
rod and the rod wouldn't turn to let the nut slide down.<br><br>
So what's in those tubes? From what I can tell, one is an assist
strut (I'm <br>
assuming gas filled) and the other is the actual lifting/closing
unit.<br><br>
