The AC is sooo cold IMO. Is there a way for it to cycle the AC on and then off and then on again. I thought Auto mode did that but I never see it cycle the AC off.

Thanks.

Just turn the temp up until it's not too cold for you. If the a/c is on, it will not cycle on/off even if you turn it up to 90 degrees.

I have the opposite issue. I don't think mine is effective enough. I'm gonna have them take a look during the 5K service.

what about raising the temperature? That should help.

^^^what he said.

The AC may run because it dehumidifies the air (hot or cold) and makes the cabin more comfortable.

Yeah I know I can turn it up. Thought that there was a better way that it would cycle on and off. My AC is so cold that yesterday it started to frost up the front window. No joke. Frost it up on the lower section in the middle.

I find the A/C to be pleasant and not a nuisence. I adjust the temperature as I see fit, but I don't mess with turning it on or off, especially given how humid it is here lately.

As far as the air cycling on and off, it won't since it stays on to regulate the humidity in the car. Only way for you to have it on and off is to do it manually.

I would get that looked at, under no circumstances should that ever happen.

I think by "frost up" he means "fog up". When it gets really humid and the dew point starts climbing into tthe 70s, fog forming on the windows is not unusual, especially in the evening.

(In Arizona, I see that your dew points are still in the 50s, even with triple digit temps, so I guess you don't see much fogging up in your locale)

If the system is fogging the windows after running for a minute or 2 then there is more to it than high dew point readings, a main function of the air conditoning is to pull humidity out of the air, I have been doing automotive ac for 20+ years now and it should never fog a window. Perhaps the case drain is plugged or there may be a slight coolant leak inside the evaporator case(this is usually the cause of fogging windows when the system is put into operation)

Look if you want it to cycle on and off turn your temp up to a reasonable temp... like maybe to 72 or maybe 80 to warm up the ice in your veins and turn the auto on...it should try to keep your car at that temp...BTW quit being a lazy ***** push the on/off button for the air

Maybe he has the air set to blow at the top of the dash (defog/dehumid). If you have it on that setting continuously with very cold air blowing, it can certainly cause some fogging near the vent.

I'm not assuming the OP is this stupid, but...well...I've seen worse, and the description fits. Plus, he's complaining about how cold it is. Sounds like it's blowing right at the windshield and set at 65.

Bichon

Again, you've been doing mobile AC in a very dry climate, which is why you haven't seen this.

The windows fogging up has nothing to do with the humidity level inside of the car. It happens because the temperature of the window glass drops below the dew point, and moisture condenses on the OUTSIDE. I note from weather.com that Myrtle Beach now has a dew point of 75 degrees, and since it is nightime there is no radiant heat. I guarantee that if you were in Myrtle Beach right now and pointed your vent so that it blows on the side window with the car parked, you'd see it fog up within 10 minutes.

I did this in Tennessee also for 8 yearsand have yet to see this phenomenm. But then again it seems as if your are referring to the outside of the car, never seen that one either...not saying it can't happen, just haven't seen it.

#1) Bichon is 100% right in his analysis
#2) I had the AC on the upper and lower set to low.

It isn't an issue as you can easily get around it. Just wanted to ask if the AC could auto cycle.
