AC blowing hot air

[Kaleza]

So today i took car far a drive and turned on the ac and there was no cold air at all. ItS working well but blowing hot air. car has 19000 miles so its under warranty , Im going to take the car to the dealership anyway i was just wondering if someone had similar issue and if there maybe is easy fix for it.

They should do a vacuum with a leak down test. Hope its a o-ring seal and not in the evaporator/condensor or compressor seal. These systems have very little freon compaired to the ones yesteryear. A small loss of freon will cause the system to not work.

Just making sure... did you toggle AC on the center screen on the bottom row? I made that mistake so many times when I got a more modern car where not only do you turn the fans on and set the temp but also press a AC button to get cold air. I hope Ford did something about the compressors vs S550s. On my 2016 the compressor made a loud pop sound and my idle sounded like a helicopter at 40k miles. It was a common failure and I don't think Ford ever gave us an answer but leading theory was the radiant heat from the headers and position of the compressor would slowly cook it to death.

Had that happen to me on my '15 GT. Was the condenser and warranty paid for it.

I had that issue, built mine April 2024 and by the next summer 2025 I had no AC, only 5k miles on the car. Had a leak in radiator and had to be replaced.

Had that happen on the 2024, I noticed it the day I pict it up at the dealer, It was a Mouse that had crawled up from underneath and chewed through a wire harness, It hadn't left the lot so they repaired it, I also had a mouse chew through some wires on the wife's VW

Its definitely leaking somewhere, because i remember hearing like a very quiet buzzing or hissing sound from vents when i turned it on. i just hope its not evaporator core, because if they take the car apart it will rattle and squeak forever

We have a culprit, its leaking on ac line going from compressor.

Hopefully just a simple fix. The A/C system seems to be a weak spot on these cars. I remember on S550s it was a common issue and many had to have A/C compressors replaced

Apparently they just need to swap that one line it should be done in few hours

Sorry that happened. At least it was an easy fix.

Thanks!!! its ok, at least it wasn’t evaporator core. And u know what, my driver screen cracked and was swapped under warranty, there are gaps in body panels, interior rattles a little, back seat squeaks, ac stoped working and with all of that i wouldn’t chose any other car anyway, and its still my dream car. So im happy!
