I'm not sure what could be the problem.... When I turn my fan dial setting from 1 thru 3 nothing happen (no air comes out), but when I turn to setting
4 (max. setting), I get the full blast of air. Heater and A/C seems to works fine on full blast. What should I look for to diagnose the problem?...I try Maxima.org, but no one reply... may be someone here have a better Idea!
