squeeling when ac is on

[m44bimmer]

My car recently started squeeling when i turn the ac on and im moving. The belts still look good. Could this be a result of my tensioner needing adjusted if so how do i do this?

Could be the tensioner(belt loose?), or could be the compressor itself. Pry the cap off the tensioner. You'll need a 13?mm socket/ratchet and a 8?mm big hex key. Loosen the bolt with the socket. Remove / inspect the belt. Spin the compressor pulley. It will probably feel grindy/sandy= bad. Install: tension pry the pully with the hex key, and the tighten the bolt. Easy to do. May work too. Or the comp is bad. Common deal though.
