My passenger door lock would not go down when pressing lock key fob...I added small amount of dry lubricant and it began to work again going up AND back down...Now however front doors lock but hatchback stays UNLOCKED...Is it me? Or is there a logical fix...Note here in NM of all places we have had a very (too much so) MILD winter, so it's not an issue with the coldness that I know of. Lowest temp an occasional high 20's and 96 days with no measurable precipitation.

Thanks for suggestions....

Maybe the airline to the lock from the pump module has split and ha caused this.
Where did you spray the dry lubricant?

 

on top of the lock button. Funny you should mention the air thing as recently when shutting off the car I can hear wind blowing from a fan at the back hatch window.

 

The air/vacuum pump is in the trunk under the carpet on the passenger side.
The leak can be heard from where the air is leaking from the hatch lock air line.
The break is usually in or close to the the corrugated hose at the top of the hatch passenger side. People have repaired it by carefully removing one end of the hose and putting a larger hose tightly over the smaller leaking hose.
