Door issues

[bjcarpetguy]

Hi, haven't asked a question in awhile. Anyway I have a 1987 class A. About 4 years ago I replaced the main door latch.
The worked great for a long time. But it has got to the point where We can't lock from inside or with the key.
However with the door open if we push the lock in it locks and can't close door.
It is the old style square latch. Any ideas. Do I just need to buy a new one?
They are about 100.00 each.
Thanks for any help.

Have you tried to pull on the door if inside and if outside push in and try to lock. Joe got the latch on our 82 going by takeing the back plate off and lubed it up and re-tightend every thing. That was 2 years ago and still working. I saw a viedo awhile back and the guy said that's the worst thing to do is close the door with the lock pushed in. Hope you get it fixed.

yes I tried both ways. Thought it might have to do with being a bit off level. As we have been parked for 9months and it has settled a bit. But even in flat parking lots, have had the same issue.
