AC not working


#1

I’m trying to figure out why the ac isn’t blowing in my Toyota Highlander. I replaced the blower motor and cabin air filter. I can tell it’s working at various speeds, but nothing seems to be blowing from the vents. Any other suggestions?

There are doors/flaps that move to direct the air to its various ducts and outlets. Some cars use vacuum, others electric motors. Maybe the control is not working. Sounds as if they are shut.

The default position is usually defrost. Do you feel air being pushed through the defrost vents?

In many instances an apparent fan switch or fan motor malfunction is a relay failure.

See if you can feel any air getting to the windshield for the defroster. If you feel the air getting there then you need to check the operation of the air vent door for the AC and heater core.
