AC blows warm

2021 Titan

I have taken this in to the dealership and they say they cannot find any problem. 

But my truck will blow out cold air that will freeze you out. It always did from what I remember.

It will blow out cold air but on real hot days 104 or more it will blow out cold air for a while on a long drive. 

But then start getting warm air to hot air. 

I will pull over shut off the truck and start it up again and it will start getting cold after I start driving again. For a while.

Nissan garage is useless to me and so is another shop. They say it is fixed. But I still have the same issue.

Thank you Scotty. Been a fan of yours for years. Just figured out how to become a member today. 

You have been helping since I think 2015 with different stuff, 🙂 I had problems with. 

It started one day when I left my dogs in the truck when I went inside someplace and left the truck running. Came back and the vents was blowing out warm air.

Well I would assume that the compressor itself is wearing out and have to run it a while and it gets hot outside. It stops working. But unless it does it for them, they're not going to replace anything under warranty because they don't make any money on it. It would have to be either the compressor or some type of electronic failure and the electronic failure would be more or less impossible to trace down unless it did it in front of a mechanic who can see what was going wrong electronically when it acted up
