Why does my a/c pulley rattle when a/c is on and engine revved up?

What is your question?

I have a 2003 Escalade ext. I replaced the a/c tensioner and still rattles.

How long has your 2001 GMC Yukon XL 1500 had this problem?

One week

Possibly rattling is within the *main drive belt* circuit. Remove belt - *temporarily* run engine to see if noise is gone. When a/c it on - it also applies extra load on main drive belt.
