Kneale and are great minds thinking alike(?).
Replaced my heatflap motor on Saturday, only was high 40's, and only started
raining when I was putting tools away.
One suggestion to every one, remove the windshield wiper assembly for easier
access to the motor down on the side of the heater box, its partially
covered by the wiper motor mount..  After the wipers are removed, there are
only three screws holding the wiper assembly in place, much easier.  Another
helpful hint, a "stubby" phillips screwdriver really helps with the heatflap
motor cover and mounting screws.
Similar heating control, temperature works fine now with the new motor and
the vacuum a/c programmer module.
Oh yeah, forgot to roll up the driver window after the rain started until
Sunday morning!  Things got a little (lot) wet, so now am drying it out, oh

HTH, Gary Anderson in Sammamish
BTW, have pictures of the install if anyone wants to see'em.
