The sound usually comes from a sound amp and this amp can act up and cause the hissing noise issue as well as speaker sound issues with it needing replaced in some cases.
As for the cluster issue, it sounds like either it needs programmed by a dealer or replaced.Usually, you have to go with a new one as it has to be programmed to your vehicle and usually includes programing the mileage to match your vehicle.I don't see a used one being able to be reprogrammed to your model.
As for the heater/ac fault, you may just need to have the dealer recalibrate the actuators to correct this issue as this sometimes has to be done after battery power is disconnected and reconnected.

I haven't tried to swap out the prom in it myself with using a used one but if you have found some info on this being done then you can go that route if you want and have it replaced used to see if it works properly.But unfortunately, I haven't tried that myself.
Usually, if it is just the knob you can replace it used and would be o.k.
