There’s a problem with my climate-control system. When I turn the fan on, there is no air blowing through the outlets on the instrument-panel. (There is air blowing thru the 2 vents immediately above the floor, and some air blowing at the base of the windshield). This problem exists regardless of what speed I turn the fan on, and regardless of which climate-control setting I choose (or whether I turn on the A/C).
This problem WAS occurring on an intermittent basis, and seemed to develop in RESPONSE TO my turning the knob to “defrost.” Now, however, the problem seems to be permanent. I wonder whether the basic problem is with the round knob that controls the various climate-control settings, as this knob seems somewhat hard to turn.
I have a 2004 Buick Century sedan, with automatic transmission (4speed) w/overdrive, V-6 engine 3.1 L.
