The drivers door on my 1995 Chevrolet van has

sluggish. I've tried WD, Silicone, white lithium,
atf, and gosh knows what else. Tried cleaning it
with brake cleaner, etc.

What's a good lubricant that lasts more than a
week? I spray it with stuff, cycle the inside lock
button up and down, and the lock frees up. A week
later, it's nearly impossible to open from outside
with a key (the latch part is sluggish).

I think the last time this happened, different
vehicle, I had to take the latch out, and scrub
it with hot water and brush and oven cleaner, to
clean it all out. Can't remember what I used for
lube.

What works?




What you may need to do is take the door apart, clean the components and
coat with a dry film lubricant. It's essentially painted on and though
it won't last forever should not wear off in a day or two either.


When you get the door open you may find one of the pieces to be deformed
slightly and the cause of your problem.


That said, taking a door apart is usually a PITA.
