Question about 2003 Chevrolet Avalanche
Ok i know this might be a little difficult to understand. BUt If you click on the link above. Find Diagram (a), That picture represents your switch, not complete but in theory. each Resistor means a Different speed. As you turn the Dial it applys current to all the resistor depending on which one it points to. As you can see the (i) represents current and lets say R3 represents "speed 5" Well in theory the less resistors the fast the speed. So the at low speed the dial will be pointing to R1 at medium fan speed the dial will point at R2 and at high Speed "speed 5" the Dial points to R3. Less Resistance More Current More Current more Speed. Now You have No R3...
This basiclly means that the who switch wihich includes Warm and cold and 1,2,3,4,5 and Defrost etc need to be replaced for 5 to work again.
No solution Replace switch
