Cold Air cyceling with AC off

[Pete6114]

Recent trip with ac off, with vents and floor chosen (no defrost), and temperature set to LOW, meaning no heat or cold air wanted. Just outside air flow wanted.
Every 3 minutes it would cycle from cold to warm during the entire trip. 50 to 70 degree range.
Am i alone?

I believe it. I really prefer full manual HVAC control to this dual climate control system that just does whatever it wants. I frequently turn it off and open the sunroof and rear slider instead. Apparently we are in the minority.

I will have to test this out.

my issue is the drive side vent closest to the door is weak af. It barely pushes cold air unless I crank it up to 7. Intact all the vent are weak and barely blow air unless at 7.

Even on my 2001 Ranger XL with “manual” controls I noticed the same. No matter which mode selected, even with AC off the compressor would still cycle on briefly every few minutes and it would cool the air. On that one I eventually found that by selecting the lower vents only it wouldn’t do that.

Happens to me too, I'm wondering if it has to do with a air moisture sensor in the cab? Mine seems to do it when the humidity is high, even with the windows open. Maybe Ford is trying to keep the windows from fogging when the truck senses high humidity? Just guesses.

The way it's always been, at least till now, is that as soon as you had it on defrost, the compressor would cycle to defog the windshield and the other windows, even with the ac off, and it would do that down to minus 4 C, or 24.8 °Fahrenheit . Below that it's set not to run to keep it from getting damaged. It would never kick in on vent, floor or vent+floor settings.

Just trying to help and not be a pain, but......that vent is opened with the wheel below it..right?

Yeah it’s fully open. I really should take it in but I just hate going to the dealer so much.
