2003 2500HD air conditioner problems

I have a 2003 2500HD my question is the air conditioner will blow cold air for a little bit then start to blow hot air for a little bit then back to cold. I had the freon checked it was good. Any suggestions as to what to do.

check the temp damper. What control system do you have? duel or single?

Does it start to blow cold again when you mash the gas down, kicking the compressor back in?

It has dual controls. Mashing the gas doesn't make it blow cold again ( it actually starts to blow cold again when the windows get rolled down).

OK my brother is having the same thing on his HD what he did since he does a lot of driving in the ranch the radiator and condenser had a lot of weeds & trash in it he took his pressure washer and it did help it but we think it's something else because it's electronic might be a part is faulty.

Do both sides go warm then, or just one side?

does it happen when the recyle button is pushed or just the air button?

When it blows warm can you tell/ or stop to see if the compressor is still running..Might be a problem in the compressor clutch or power feed
