So, has someone come up with a "fix" for this other than the (usta be $60)
$80-something replacement motor assembly?  I replaced mine a couple years
ago, thinking  the old one had lasted for 10 or so years, so I should get
good performance for another eight to ten years.  But I'm noticing now that
if the ambient temperature is, say, 30, and I've got the car set to , say,
89, after an hour of driving I'm feeling cool or even cooler (not quite
outdoor) air from the dash vent that warms the side window.  I still feel
warmish air from the footwells, but my left hand on the steering wheel is
getting cold.
