Might not be any problem....depends on what type of system you have. Is it getting cold?

It could be overcharged or it could just be normal. It will only cycle if the pressure drops low enough and that usually won't happen on "high" blower setting at idle.

It wont even cycle on the lowest setting. It used to cycle on high before the recharge

That would be because it needed a recharge...........

That's the first sign of low refrigerant is short cycling. It won't cycle unless the pressure drops below 24 PSI so if you have a gauge, you can check it.

What is this vehicle anyway? Cycling is a matter of load, charge and temps. Pressures and temps need be taken and leaks fixed if found,

Guess: It's a Vortec with Delphi POS compressor leaking like a sieve. Green dye (UV) but you can still see it on body of the typical OE ones with dye used when new.

They use Teflon in those which ruins condenser and if left to cycle too much in high heat it will self destruct.

You need to post pressures and the temps at what RPMs at what A/C settings. That or brace for a few grand if a single system - more if dual! Takes money and know how to do this yourself but you can save some impeding damage,

Answering the original question and ignoring the leak issue for the moment, the lack of cycling is completely normal for a fully charged system on a hot day.

So correct - lack of cycling IS normal is hot enouth and the system fully taxed/maxed out. Unseen or noticed it probably normally would cycle at highway speeds.

The temps and assorted obserations would tell tons as to wether this is a problem or not,

It leaked around the ports and they were replaced before the recharge. So hopefully that fixed the problem. I guess I will just run my ac. I was scared I was going to burn up my compressor or something thanks.

IMO and with some experience: Don't worry about a non cylcling compressor when you watch it at idle speeds. It will shut off by itself with excessive pressure or low pressures which mean two things - it's cold enough or low on charge.

When and if your hear that POS compressor make noise get it unplugged that moment and get a new Sanden clone for it before it can destroy more. Got the T-Shirt!
