2012 GT. Base model with manual fan control. I noticed about 3 weeks ago that it sounds like it drops speed(and airflow drops off as well) randomly. Meaning I can be fine for most of the day, then at any moment it will slow, then speed up, slow. Yesterday I had it on max and it felt and sounded like it was on the lowest setting. But then while cruising on the highway, it all of a sudden started working perfectly fine again for the rest of the day.
It does this regardless of setting on the ac (recirc/closed, max AC, dash vent, floor vent, etc.) I rotated the knob several times like you would on a old stereo to get the contacts clean, but that made no difference. Anyone heard of this before? Any clues on where to get diagrams so I can start measuring voltage to see if its the blower motor or some sort of control issue? The intermittent problem makes it tricky to evaluate at home.
