No Cold Air? This looks like a really clogged up home A/C filter right? It's an evaporator that on a vehicle is meant to allow air to flow through it and cool down your vehicle's A/C unit allowing it to work properly. This, however, is a seriously plugged up evaporator with very little air flow coming through! The A/C Evaporator did not get this way overnight, providing warning signals along the way such as the car wasn't cooling enough.
