Good day.

I have the standard A/C with manual temperature control in my 2022 STX. I have a basic question about operating the A/C: does the temperature setting determine how frequently the compressor cycles? I ask because the compressor's frozen up two or three times now*, so as a test on a recent long, hot trip I turned the temperature three or four notches warmer than coldest setting and the A/C worked fine, seven hot hours each way, plenty of cool air. I'm curious if by setting the temp a bit warmer than cold the compressor's not cycling as much. I've always, regardless of vehicle, set the A/C to max cold, no recirc, and then just adjusted the blower speed ...

* That's how it behaves, anyway: cold air stops and the blower doesn't blow. My dealer says I have to bring the truck in with the A/C malfunctioning for them to do any troubleshooting; I guess that makes sense, but it happens so infrequently I'm not likely to be within a convenient distance of a dealer.

Thanks for any suggestions,
Jim
