My 2009 RAV4 Limited had an A/C issue a while back that was corrected by a mechanic, but seems to have come back - when the mechanic looked at it, he mentioned that two of the valves (the ones where you recharge the refrigerant) were leaking - so those were replaced, then he also mentioned that the clutch or something on the compressor was not engaging, and that it seemed to have a lot of "torque" from the compressor trying to work.
Whatever it was he fixed it and I was good for about a month and now it's blowing warm air again.
Could it be the same problem again, or something different?
I am on the East Coast of Florida - Vero Beach.

How long is a while back? Can’t you take it back to that shop and tell them their repair didn’t work? Your compressor doesn’t have a clutch, it’s a variable displacement compressor that’s always on. If you would like to know more about the system, check out this pdf:

It also could be the flow sensor. Easy to test with a magnet:

DTC B1479 A/C problem

Hi, I found out that my 2009 4WD RAV4 (manual a/c) has DTC B1479 code stored in the a/c unit and it blows hot air. I'm thinking of applying the simple solution that I found on the Lexus club forum "RX350 2010/2011 Air conditioning DTC B1479 cheap solution" that has very good tutorial with...

It was about a month ago, the mechanic that looked at it for me, didn't charge me anything for the repair. I took it back to him today and he said we need to replace the compressor. Thanks for sending me the PDF. He is telling me I'm looking at about $1,000 for parts & labor.

Did you test the flow sensor?

Not yet, I have zero mechanical knowledge and wouldn't know where to begin, I need to thoroughly go through the resources you sent me and figure out what to do. I'll watch the video and see if I can figure out what to do.

I believe I read somewhere that can you put a magnet on the flow sensor and if the AC works then the sensor is no good.

Someone else might remember it better than I can.

I found the post.

2011 Rav4 AC not working/ Blows hot air

@2011RAV4 did you take pictures where this flow sensor was located ? No I didn't take any pics. I was just trying to get it done! Here's a couple of stock pics. I will try and take a couple tomorrow! It;s small the opening on the compressor is only about the size of a quarter! You just...
