ya this is like the tenth thing i have to go in for service for and i dont beat on trucks i think the dealership broke this because they insisted on inspecting it last time and they took it apart ever since they put it back together it has been having problems so i think something when back wrong or something

that loud ac noise is coming from the compressor.its trying to run with a high backpressure.its either the condenser is really hot(fan not working properly)or the expansion valve in the evaporator behind the dash has a resriction,also happens when to much freon is put in the system.both are bad and could damage the ac compressor.
