No bc I don’t know how to do any of that. The pulley stuff. I’m just a basic guy asking about my vehicle I don’t know Jack other than how to fill my gas and do my oil.
ok, here is a simple way
get a helper, wife, girlfriend, kid, boyfriend, neighbor, bum off the street -whatever
park the vehicle, pop the hood, start it up and have the (other person) rev it up in park, have them turn the ac on while you listen under the hood.
listen carefully while they rev it up with the ac both on and then off.
this is one place to start
note that sometimes when the ac pump goes out it will be fine at low idle and will still work just like it should, but rev it up high and then you will hear the noise if it is going out.
