There is a procedure for recalibrating the dampeners on the A/C system; I did that to my 2007 H3 Base a couple of months ago and have not had any issues since.

Here's that procedure...

HVAC ACTUATOR RECALIBRATION

1. Ignition On, engine Off.
2. Turn TEMP dial all the way to right.
3. Turn blower control all the way to right.
4. Turn mode selector all the way to left.
5. Simultaneously press and hold the A/C and Defrost buttons until LED flashes.

When LED’s stop, calibration is complete.
