Loose door lock

Hey little problem with my '01 Montana. The door lock on the manual sliding door is loose and jiggles a lot. It doesn't always lock, even if I'm using the fob. I figure some little part is broken in there but I don't have the time to go on a long exploration through the door panels-plus its 30 degrees in Buffalo, NY. Any Ideas?

Thanks,
Doug

Sometimes the black plastic slider just comes off of the lock rod. When it does it binds the rod and prevents it from locking/unlocking. You'll have to remove the panel to see for sure.

Thanks. I hope its something that simple. It would be nice if the only thing it cost me was a Saturday afternoon...

Ah, but the cost goes up as the weather gets nicer.:2cents:
