Look for vac hoses damaged or dislodged. System is designed to fail in defrost mode.

2005 Astro Van AC only blowes through windshield defrost vent


The mode doors in the dash are powered by engine vacuum, if vacuum is missing the default setting is the defrost vent. Look under the hood near the firewall for a disconnected vacuum line.

2000 chevy astro cargo van. the heat registers on the gage but little comes out and only out defrost. thermostat????


If it is blowing hot air out of the defroster and not out of the heater vents then the door that directs the heat from the defroster isn't working properly it is blocking the heat from going to the heater vents. Also check the cold air door. It sounds like it isn't closing all the way to shut off the cold air and not letting the hot air pass.

Ac is blowing hot air front and back= chevy astro van 2003


when you turn on ac look for front ac clucth to be turning. if it is feel the lines up to the cowl if they are cold 40 degrees or so theres probably enough charge with the year of that vehicle it maybe low on charge ac systems will usally hold for at least 5 years.

Don't get any air from vents on 1998 Chevrolet astro van. Just replaced clutch fan. Air cond. works fine and fan works fine. Is something not connected?


SOUNDS LIKE THE AC CONTROL HAS LOST VACUUM FROM THE ENGINE, YOU MAY HAVE KNOCKED A HOSE OFF WHILE CHANGING THE FAN CLUTCH, IS THE AIR COMING OUT THE DEFROST VENTS BY CHANCE?

i suspect the vents are controlled by vacuum and are not opening due to a vacuum leak.

Replace the broken vacuum line that runs across the top front of the engine.
