I searched and couldn't find anything pertaining to this issue. I have a 2014 and when i have the climate control in auto mode set to 74 it will blow super hot air after engine start. It blows hot air for probably 10 seconds or so then you here something move and it will start blowing cold air again. This seems to happen around every 10 engine starts or so. Anybody ran into this issue? Would rather try to fix it myself then take it to the dealership. Thanks for your time and help!

yep thats it too. i took it in a few weeks before it started for what sounded like a vacuum leak to me under light acceleration with the windows down. Sounds like a whistle but the mechanic told its the plastic air intakes that cars use now and nothing was wrong....> I am still saying its not right because my 2 previous frontiers never had that whistle.

It's not a matter of the compressor taking a second to cycle on. It's the heat that is on, you can hear the blend door moving and it switches to cold air at that point. I should note that mine does it after I shut the truck off and restart it after driving for a bit. So the heater core is already hot from coolant. It's definitely a blend door issue. Gonna investigate more today. It's annoying because im worried it's gonna get stuck on hot. Which is no good in Florida lol

Exactly. It is the full blown heater going and mine is after the truck has been driven a bit too. I am sure it does it when the engine is cold but you can't tell cause the truck isn't warmed up yet.
