4kq misc questions

[snowphun <pajono@compsol.net>]

A couple of questions for the knowledge mass:

Door locks: My front two open when I turn the drivers door lock, but the
rear two do not. They move just slightly, as if they're trying, but to
no avail. Sounds like a pressure leak? Any ideas where to check? (the
only reason I care is this will give me twice the chances to get into my
car when the door handles stop working in freezing weather).

Heater: The heat seems to be a bit finicky. When I bought the car last
April, it blew hot air regardless of where the lever was. Then one day,
it started blowing cool air if it was all the way to the left, but the
slightest movement to the right blew very hot air (what a PITA).
Anyways, it now has a bit more of a range, but seems to fluctuate an
awful lot. Any ideas? The cable and the coolant valve seem to be
operating correctly...

Thanks a bunch guys,
