Vent Blower failure: Past 4 months on 4 occasions vent blower intermittently would not come on but would come back on after 15 to 30 minutes, approximately. The last 3 days of vehicle operation the vent blower motor does not come on at all with the first of 3 days the blower could be heard running at an extremely low speed. The vents at windshield and blower filter have remained free of obstruction and well maintained. The vent blower failure impacts safety to myself and others due to the inability to mitigating fogging on the windows which severely impacts visibility. The problem has not, as of yet, been addressed to my dealership/independent service center: Owner has extensive electronic & electrical background and is an expert troubleshooter. The harnesses at fuse panel and blower motor have been verified and appear proper and the fuse was not blown. I do not have a schematic of this electrical system and voltage at blower harness was not checked. (My thoughts on problem areas that may be impacting this safety concern whether it is an isolated case or widespread problem: Blower Motor - failed windings, thermal overload, bearings, and brushes/pitting as applicable. Vent Controller component failure. Wiring and harness issue.) I intend to bring this safety concern issue to manufacturer or dealership or independent service center as it is affordable. Symptoms: See first paragraph. The blower failure was 4 times at car start-up and once while driving.
