power sliding door will not latch. you have to push it to get it to lock into place. Can it be replaced by the owner?

Sounds like the power slider latch assembly or track have gone bad. I'd take this to the dealer. You'll need the parts from them anyway, but they will be able to diagnose the problem so you're not just replacing parts.

This sounds like what I'm experiencing. I just came back from Dealer, They tell me it's a motor. Almost $700 before labor. I disagree. If I get down close to the bottom of the door near track, I hear a slight metal to metal grinding sound. Showed it to mechanic, he said all do it. Went to other side, it doesn't do it. Finally they admitted they didn't know what was causing it. I'm stumped.

I had this problem a few times and what I found was that it was the rubber piece on the side of the door that had come part way off and was not able to close al the way even though it was an inch from closing. Hope i was helpful!

I know this is old, but I have the answer so figured I would post so others can see. Mine did the same. If you hear the motor working and hear a metal to metal sound then the cable in the latch assembly has broken apart. It is a 6 inch cable. The bad news is you can't just get this part, you need the whole latch assembly which you can get for about $130ish on ebay. It is an easy fix. It is held on by 3 bolts on the back of the door and 3 bolts inside the door. This will fix the problem.

Yes it's old turkey pig but the problem is older, your suggestion is probably correct, I've tried replacing rollers with 10 cent nylons, but they wear quick and aren't exact, now gonna order psd assembly and make sure they are lined up , than it may be the latch assembly next, these doors need a recall.

When I was having the sliding door would not latch problem, I read somewhere else (sorry I don't remember) that an old. weak battery could be the cause. After a couple of months of putting off the repair, the battery, which was over three years old, went totally dead. I got a new replacement battery, and now the door closes properly.
