2000 C5 AC issue - AC squeals when on
Hello everyone- I searched the forum and couldn’t find something similar so I figured I would throw this out there. My apologies if I missed it,
My 2000 C5 is having some AC issues. Right now after the AC Runs for a while it starts to squeal. The kicker is it really get louder when I turn left or right. It’s not that bad going straight. It also starts to leak water into the passenger footwell. I drove to Carlisle for 3 hrs each way last week and no problem at all. No noise no leak.
Now I had the same issue back in June and my mechanic checked out the AC drain by the engine block and it was clear. They also blew out the lines and refreshed the refrigerant. It was was working fine until today.
After doing some research here on the forum it sounds like the compressor is going, ac pulley or belt but I can’t find a thing that explains the leak or why it gets louder when I turn. Once the AC is off it all goes away.
Any thoughts would be greatly appreciated!

If you have water in the footwell, they didn't clean the drain out good enough. I would pull the rubber hose off the bottom of the Blower motor. Be prepared for a 1/2 gallon of water. If it's holding water, you need to roto root your drain from the firewall. There are plenty of posts about that PIA job.
Is it squealing inside or outside? If it's inside, I'm guessing your blower motor is under water.
