Sometimes you might hear a sloshing noise in your dash as you drive. While this can indicate air in your cooling system, it also could indicate a clogged AC drain if it’s accompanied by a bunch of water washing out of the HVAC when you make a turn. This sucks, but it has an easy fix. What happens is your AC’s condensation gets trapped inside the HVAC ducts. This is often due to debris clogging the drain tube in the HVAC. You can simply blow out this debris with compressed air and all is right with the world. This video shows this problem and how to fix it in detail.
