AC Not Working Properly!

Hello Everyone, I've been searching around the forum and it doesnt look like anyone has experienced the issues Im having. So our AC seems to work great when we initially get in the car. However, within about 20-30 minutes of driving it starts blowing warm air. The fan works just fine, cycles through all the speed settings, AC light is on, but it almost seems like the AC stops working and the Vent kicks in. We can hear everything working just fine but the car stops producing cold air. And of course, this always seems to happen to us when it is 90+ degrees out. I took it to a local shop and they tested the pressure, made sure the AC was charged and everything checked out just fine. They even held on to it for an extra day and ran it all day at their shop (idling) and the AC worked great! the car was an ice box. However, put it under some driving stress and within 20-30 minutes.. HOT AIR!! I'm stumped... Has anyone experienced anything similar? Were you able to fix it? What was the cause? Any guidance would be great! Thanks in Advance guys.

Your system is like OVER charged. If it has too much of the refrigerant in it, it is probably slugging the compressor and not allowing it to properly charge. Good news is the system is still holding pressure, so you can have it vented or purged and then vacuumed and refilled to the proper amount of r134a.

This is all just from a bit of reading I've been doing to recharge my AC in my truck. I'm not an HVAC tech or nuthin. ...please take this with a grain of salt. Haha.

the weird thing is we had never charged it. I know the shop mechanic mentioned he was going to charge it, but he said it had plenty of refrigerant.

Hmm. Not sure then. I know how much that would be pain in the rear to not have AC in the heat... Trying to get mine buttoned up as we speak.

Sounds like your compressor clutch is worn. There are usually spacers in there and you can pull one out to reduce the clearance.

I guess I need to check the blend door and compressor clutch. Have either of you swapped out the compressor clutch or blend door? I imagine the blend door is a much easier fix than a compressor or compressor clutch.

If the blend door is where I think it is, it's nearly as difficult as the heater core I just did.

Entire dash has to come out and the dash support has to be removed from the frame. It's a bear.

Not sure what somebody said meant by venting, but never “vent” refrigerant into the atmosphere. It is a very large fine and is bad for the environment. It’s a $32,500 fine if caught doing so. Have it properly recovered and recorded by a licensed epa 608/609 technician. I have my epa 608 license and would strongly recommend a professional to assist you.
