AC Fan cycling excessively?

[Supertech1]

Wondering if anyone else has experienced their AC fan, or compressor, cycling on and off excessively? Mine cycles on every 10 seconds and runs for about 3 seconds.

Does not matter about the AC temperature setting or if I’m in drive or park. The only way to stop this is to turn AC off.

Before I go to dealer, Anyone else experienced this?

Thanks

Do you have it set to Auto?

I wouldn't say excessively for me but mine will kick on and off on auto when I accidentally press it because I never run auto lol

Mine does, excessive? well - yeah I'd say more than I've ever heard in a vehicle. I can hear it in my with the windows up at a stop light... does cycle a lot, doesn't matter the setting of my HVAC either... HVAC could be off and it cycles - agree seems like a lot.... maybe because of the turbo? was going to ask about it at my first service.

I know one of the new things they did on this engine was put some valves for the engine cooling so they can control when coolant cycles through the cabin climate control that way it's not sending hot coolant through when it's not trying to heat, etc. This may be what you're hearing?

I'm having this same thing, and when the fan turns on when the truck is cold, it shakes a bit. So weird.

Could be. Based on the other replies, this does seem to be by design. I’ll probably due as Sner planned, and ask about this when I have the truck in for service.

Mai reason I asked was because I didn’t recall hearing this until the last 2 weeks. Started around 1000 miles, best I can tell.

I did not. After you asked, I set AC to Auto and have the same cycle repetition.

No it's cooling fans for sure cycling on and off... one good thing, glad someone asked the question - at least it's something we are all listening to.

mine did it from day 1 - and it now has 1500km on it. To what @mitchfon said, I notice a shake in mine as well at times.

I get the same occasional shake but fan cycling seems unremarkable at this point. Temperature gauge holds steady. I’m in SC where we’ve hit the upper 80’s already.

I don't notice any shaking and I've been sitting out in mine fiddling for a long time trying to figure out why the upper vents whistle slightly when ac is on . When I first bought the truck I did notice it was on 'auto' and the thing would constantly be on/off cycling. I turned 'auto' off immediately.

Well is it the fan, or the compressor?

 

[Kjc]

I'm glad this seems to be normal... My fan kicks on right after I start the car... Not sure if it's doing it while driving but definitely when idling in park/drive.... In will turn off and on maybe twice in a minute... I've never had a cooling fan turn on/off so much..... Like others said... No hvac in use just sitting with the windows down... Also I live in Alaska we haven't hit 60° yet this year

Is it just me or is the AC compressor clutch also really noisy?
