No overheating, no leak in coolant. A/C works great. I was told to clean my vents, but how?

    The heating and ventilation draws its air from the area at the bottom of the windscreen/wiper panel area, make sure leaves and debris are cleared from this area. I have had to remove the fan blower motor on several cars and remove a "nest" created by rodents in the heater ducts. Not sure if your car has a cabin air filter if so probably located behind the glove box, perhaps its restricted.
