ac problem
hello i have a 2014 silverado iv had about a year and ahalf now but recently iv been having ac problems.the air comes out hot and cold and has good pressure but when the air is on theirs a screeching noise coming from under the hood.and a sound like metal scratching and hitting.if i drive with the air on the belts get kinda tugged back and sounds like the trucks breaking down but when the air is off it works perfectly.no issues at all.anyone have any ideas???i cant take it to chevy because im over my warranty miles and powertrain wont cover anything but motor and transmition.
