where can I purchase a resistor for the high speed on my heater blower
Dear barcher1-- The obvious place to find the part you need for your 2004 Chevrolet TrailBlazer would be your local Chevrolet dealer. Take advantage of their inventory and also be sure to take advantage of the knowledge you can gain from talking with the man at the parts counter. These parts men usually know more about their brands than anyone else in the dealership. Good luck from Bovan.
