I have a 1999 Lexus es300 automatic and when I am driving the ac light starts to flash and the air turns very hot and humid. When the car is started cold the ax works fine. But once warmed up it is hard to get it to stay cold. Have replaced the fuse and the sun load sensor because it gave the code 21 when doing the ac diagnostic in the car. Any help would be appreciated. It has 170k miles.

That usually means the clutch on the AC compressor is going bad I would replace the entire compressor clutch assembly myself
