Last year on a long trip during very hot weather, my 2003 Honda CR-V’s A/C out temperature dropped and I could notice what I felt was humidity or moisture in the air in the car via smell, the air just seemed to go mist. A few minutes later it went back to cold, but it get doing this as I drove. Honda say nothing wrong with the A/c and suggested I keep the one switch in re-circulate so I would not pull in outside air. They also suggested re-charging the system, but I felt if the system were low the output would be constantly warmer than expected, not vary. Leaving it on re-circulate seemed OK until yesterday, it was 95 or so, I was going down the interstate, and the output started changing again even though the re-circulate was on.
Looking for any thoughts on this. Does it sound like recharging the system would correct this? This typically happens on the Interstates when I am travelling fast - I can’t recall it happening in city driving. I can’t make it happen so I feel that wherever I take it they will see nothing wrong and suggest the re-charge.
