2007 tundra's ac is blowing hot air.

I have a 2007 Toyota Tundra. The AC started blowing hot air and I had the system Recharge with refrigerant. About four days later, it was going hot air again. I’ve gotten a vacuum hoses dye all that stuff to test the system. I can’t find a leak anywhere so I’m reaching out for some help to figure out what possibly could be wrong with it. The compressor does not seem to be bad. It would kick On after I refilled it with refrigerant so I don’t think it’s that. Any help is appreciated.

 

My 07 when I bought it new. Did this for years. Ac worked then didn't, then did.

Turned out to be 1 relay.

 

I put a USB cable behind the dash which got sucked into a gear on the blend box and mistimed one of the servos. Others have had their gears break. Check that all of the blend flaps are actually moving and one's not stuck in heating position.
