Thanks for the information. I ended up recharging it to the max charge level and just running it for a few days. So far it seems to be cooling ok. Maybe the cycling was a function of the temperature. After checking the charts, the pressures seem to line up. Thanks for that!

I have an 04 4.7L V8 Limited with 205K. My A/C generally cools OK, but the compressor cycles on and off frequently (5-10 seconds). Over the past couple of years, I've had to add refrigerant a couple of times to get it to cool well. I now have access to an A/C machine so I decided to recover...

I'll check the cabin temp sensor also, I think you're right that this could be a likely cause. Should this show up in the diagnostic mode test? From everything I can tell with the gauges, the system appears to be cooling as it should, I'm just baffled why it isn't translating to cold air. Is...

Thanks for the advice. I also thought it was odd that they didn't read the same pressure. This is a different set of gauges from the first set I rented, so I'll recheck everything tomorrow. How difficult is the blend door actuator to get to and how would I go about checking the heater valve?

I rented some gauges and checked pressures again. Temperature is about 95 F outside. Engine off pressures are 65 psi LO and 175 psi HI. Engine on compressor off is 85 psi LO and 125 psi HI Engine at 1500 rpm & compressor On is 30 psi (0.2 Mpa) LO and 225 psi (1.5 MPa) HI Per the book, the...

Thanks for the replies so far. I looked at the sight gauge and it is clear while running, but doesn't seem to foam up at all when you turn the compressor off. From the manual, it says that it could be possibly overcharged when this occurs. However, looking at the pressures and from your...

I took it the filter out and cleaned it and it definitely looked like yours. I'll get a replacement for it tomorrow. Thanks for the tip.

Mostly clear while running. I'll try to get a picture. The service manual was a bit confusing on what it should do, but from reading here I've gathered it should be clear while running and foam up when the compressor is turned off. Is that correct?

Hey all, My A/C hasn't been cooling as well as it should over the past couple of summers, but I've just dealt with it as I couldn't quite figure out what was wrong. I've read through the various A/C threads on here and looked at the factory service manual, but still can't nail down the...
