1995 ford aerostar xlt rear side door won't open from inside?

Answer 1

You'll do it much the same as I did. Get a can of WD40 with the new Smartstraw built in.

Spray it into the lock. Spray it into every orifice relating to the lock. Try to work the lock.

If that doesn't do it then take a screwdriver and remove the interior of the door so you can see the mechanism. It's quite a complex linkage.

Ford install a kind of a white grease but that has gone dry. Grease is actually a soap with some light oil dissolved in it. It releases a bit of the oil at a time. Eventually it releases all the oil. Light oil dries up, actually evaporates, over years. WD40 is a mixture of light and heavy oils and after the light part evaporates there is a tiny amount of heavy oil that makes a thin coat.

I usually follow up WD40, not with grease, but a heavy oil which is water resistant, very slick, very long lasting, doesn't stain clothes, doesn't harm rubber or plastic and doesn't smell bad as motor oil and gear lube do. It's olive oil.

Olive oil doesn't move in immediately but it will follow the lead of the penetrating WD40. In a few days locks will open and close at a touch.

Spray WD40 onto the rollers in the grooves for the side door as well to make them move smoothly. I get olive oil into such places with a bit of sponge or a paint brush.

Then do that with every lock, hinge and pivot you can reach.
