The A/C - Heater Assy carries different part numbers. Most Asian vehicles have wiring harnesses which are model specific so this could probably entail having to replace the main, dash, and cowl - front harnesses. The cost of the conversion would not be in the parts (if you could find a suitable donor vehicle having all working components) but in the labor having to R&I the other harnesses, unit, and sensors. The other issue is that you would have to make certain that every fastener, screw, bolt, and nut was saved and the only way to do this would be to remove the Auto Climate system yourself. This would be a major rewiring job and not for a DIY having less than expert knowledge.
