You and he are correct... there is a lot of heat load under the hood.... but it’s the same heat load I had when it used to blow 38* less then 2 years ago...

Here was all of my numbers from 2 years ago when I first charged it.

At first I thought the charge may be a little low but, after checking pressures in these higher ambient temps, the pressures seem more in line. So I didn’t add any Freon. I was worried the high side pressure would go to high. So I’m not sure what to do now. I know it’s something with the AC system a...

This is how I can tell the compressor is on/off. The laptop shows “AC ON” which means the compressor is on. And it cycles a lot when driving...but at idle it’s pretty steadily staying on.

So today while driving, it took about 10 mins to get into the low 50s vent temps. At idle I’d see 49-51* and the compressor stayed on pretty steady. When driving the temps seemed to increase to about 53-57* at 50-60 mph (2000-2200 rpms) and the compressor seemed to cycle on and off a lot. I can see ...

That is the picture with 111* on the thermometer. Pic 2 on this page.

Engine revved to about 2000+ rpms.

Engine speed revved to 1500-1800 rpms,
All other settings are the same.

Idle at around 1000 rpms, AC on Max, doors shut, fan speed on 3. Vent temp around 53*.

Ambient temp at the radiator. 94* outside but hotter in the garage.

Pic test..
