so my 2013 model S is not blowing cold air anymore. Also, the heater is no longer blowing hot air. No error messages, but from research I believe the AC compressor and possibly PTC died causing the dc/dc fuse(s) to blow. The vehicle is out of warranty and i'm not trying to spend $4k to fix. Will driving with it unfixed potentially cause a battery degradation issue? as the AC is used to cool battery while supercharging? Even though its cold outside? Can I buy a new compressor and vacuum out the r134a, bolt up new unit, and recharge, with the vehicle off? Can i just throw in some new fuses in the DC-DC? Or does it need replacement?
