After engine warms up, I turn on ac and it squeals, it’s not the belt, could it be the compressor??

  1. How do you know its not the belt? Did you spray a bit of WD-40 on the belt while its moving and listen for the noise to quit? This is how I test them. But if you know for sure its not the belt, it could be the compressor or an idle/tensioner pulley as well.
