AC not cold

Don't want to sound like an idiot but don't I need to have the system discharged by a professional prior to checking the orifice tube? This doesn't sound like something I can do myself.

Thanks for the advice thusfar. I appreciate you getting back to me so quickly. I've removed some of the plenum on the passenger side as well as the center console in search of the blend door motor. Could you guide me to where it is? Is it behind the A/C switches in the dash or elsewhere? I've also checked the vaccuum lines and solenoids and they all seem fine. Thank you again for your help!

Not to be rude, but wasn't that what I asked on my previous post."Is this something that I can fix myself or should I go to a professional?" If I hadn't read in Haynes about discharging the system prior to checking the orifice tube screen, who knows what could have happened. Your post at 12:10 to my previous post said nothing about discharging the system. You only said I needed a special tool and that a parts house should have it. Thanks for the information that you provided but I probably could have had a free A/C check at a local shop and gotten the same info.

I just finished fixing the vacuum hose problem that is common on Astros-- causing no air through dash vents. I pulled the dash and the doghouse, replaced the entire small vacuum line as, well as line from T connection to the vacuum ball. I have LOTS of air flow now-- BUT, now it's not cold. It was plenty cold before I 'fixed' it and the rear air worked great. Now neither front or rear is cold. I'm guessing I disturbed a wire somewhere. The compressor seems to kick on OK and you can hear the stronger airflow when switch is in MAX position-- but it's not cooling. Any help? There is a wire connection on the top of the doghouse that I unplugged when removing it. Of course I plugged it back in-- What is that wire? Any thoughts what I did to stop the cool?
Thanks!

Thanks-- I don't know "Heater control valve" and "blend door". Can you explain a little more? Where located and what I might have done? I'll check the vacuum harness.

Thanks-

Hi Guys,

The air in my van is blowing cold through the rear vents and also through the floor vents up front. However, the front vents in the dash are not blowing anything. For a while, they simply worked on the middle and highest speeds. Then they worked intermittently whenever they wanted to! Now they do not work at all. The air is on and works just fine through the other vents. What could be the problem? Is it something we can fix ourselves? We live in Florida and so garages charge an arm and a leg to fix A/C problems because they know you can't live without your A/C here. Any advice would be appreciated. Thanks

My Chevy Astro Vans front air vents blow air but not cold. The rear air works fine blowing cold air. Is there a way that I could repair the front air conditioning or is the problem serious enough to take to a repair shop.

Thanks
