Well, baby powder works but I'd try to find out why it's squeaking in the first place. Belts squeal because they are slipping on the pulleys they are passing over. I'm guessing your a/c button is lit up when you turn on the heat, causing the rpm to go up and the a/c compressor to cut on puting more resistance on the belts. I'd try narrowing the noise down but if the belts are old, you could try replacing them and keeping the old ones for spares.
