Occasionally, and it seems to be only the hotest days, the HVAC fan acts up. Sometimes the fan comes on as it should then slowly slows down to just a trickle of air or none at all, regardless of the switch setting. Sometimes it blows at about speed 1 when set at 5. Never blows harder than the setting though. Sometimes when turned off and left off a few minutes it will operate properly when turned back on. When doing its "trickle" stunt the air coming out is cold, so I know the AC is working, it just won't blow. I don't think it is a switch problem, I suspect blower motor (brushes) or relay (maybe). The cabin filters aren't plugged. What do you all think?
