A system and method for preconditioning a vehicle interior via a remote start device based on then-current weather conditions independent of the previous climate control head settings in place at the termination of the vehicle's last use are disclosed. The preconditioning system and method may be used in either electronic automatic temperature control (EATC) systems or in manual temperature control (MTC) systems. When used in conjunction with an EATC system, variables including sunload, Tset point (that is, the temperature door position), Tambient, and Tcabin are used to calculate the climate load demand. When used in conjunction with an MTC system, Tambient, Tset point, and Tcabin are used to calculate the climate load demand. In the event that the MTC system does not have a Tcabin sensor then Tevaporator thermister is used to calculate the climate load demand in the beginning of the remote start. The disclosed system and method also has windshield defrosting/defog and rear glass defrost capabilities. The disclosed control strategies are also capable of turning on/off the heated/cooled seats (when present) and the heated steering wheel (when present) according to the cabin thermal comfort conditions.
