2002 Cadillac Escalade Question: there is a loud squeeling and chattering noise when I accelerate with the a/c on

GM has a bulletin out about this issue. The cure is to replace the A/C compressor. The original compressor causes the belt tensioner to become damaged from the startup load on the belt.

is there a recall on it?

You may have bend reed valves in compressor if you turn the compressor around ten revolutions it may bind verifying the internals are bad.
