It has a cabin air filter according to Google.Never because I think the 07 predates CAFs.

Look closer. CAFs are only part of the deluxe auto temperature package. Standard controls it isnt included.It has a cabin air filter according to Google.

It was indeed idling. Was doing it solo. I'll get a helper tomorrow and try again.
It was. I hooked up a refill kit and had to add a bit. Its back in the green, and now the compressor sounds better and not as switchy (you could hear the clutch engaging and dropping regularly). Still no cooler out the vents. but we will see tomorrow.
The DIL used the low side gauge only method like you to boost her a/c last summer and ended up with a new condensor after the now excessive charge on the high side evacuated thru the tubing sidewall, just saying.
The kit I purchased had a handy gauge on it so you knew when to stop. It wasnt one of the old style kits with just a hose and a valve.
He's saying that the pressure reading you saw when connected to the system is not the same as on the high pressure side of the compressor when it the A/C is actually running at capacity.

Some cars are under condensed. When you go to a shop that does a lot of this work r
They have some sizable fans that sit in front of the grill simulating driving. Also doing this at idle is not good either.
If the pump is not up to speed the pressures will not be right. I seldom if ever put the high side gauge on the system.
If the AC system has the proper charge and the high AND low pressures are where they should be and no indication of a blockage etc, you should be looking to see if the temp blend door motor/blend door are working properly. If it isn't going to full cold position the temp at the vents won't be as cold as they should be.
Keep in mind on an automotive AC system with R134A, you can really only expect @ 30degree difference compared to ambient temp.
Make sure there is nothing blocking the condenser (those dang cotton seeds like to gather there) also make sure the cooling fan is working & if equipped with 2 fans both should be running when on Max AC (you should always be checking ac operation on max ac).
What kind of vehicle are we talking about? Year make & model?
Its a 2007 Town and Country.
Wife had me drive it to work today so I could see if I could replicate the smell.
I couldnt.
I also had to turn the AC blower down because I was getting too cold. Problem appears to be fixed.
I had it running for over 90 minutes total today. I even saw how bad traffic was on all freeways so I drove from 30th all the way down Emerson to 465 on the south side so I gave it a mix of highway and city. I couldnt get it to smell, and It now gets plenty cold. (and the compressor no longer cycles)
Shouldn't need a fan to test AC operation. If it is working properly it should be just as cold at idle as when driving. If the compressor is working properly no reason to raise rpm. A guy just argued this with a GM instructor yesterday during an AC class (supposed to be about 1234yf systems etc but also talked 134a). They are doing some cool new stuff on auto ac systems

I take a similar detour coming from Lawrence on the way home sometimes. If 465 gets backed up I'll bail at Washington and take Emerson to the southside and get back on 465 (unless it's still backed up, and then I'll just take the surface roads ).
