Systems and methods for providing heating and cooling to a cabin of an autonomous or semiautonomous electric vehicle. A system includes one or more autonomous or semiautonomous electric vehicle components generating thermal energy as a byproduct of operation, a radiator fluidly coupled to the one or more vehicle components and positioned downstream from the one or more vehicle components such that the radiator receives at least a portion of the thermal energy, a thermoelectric cooler thermally coupled to and located downstream from the radiator, and one or more bypass valves that control fluid flow from the radiator such that fluid flows directly to a cabin of the vehicle or flows through the thermoelectric cooler before flowing into the cabin.
