2005 Colorado Fan Speed

[carthman]

Bought a 2005 Colorado Z71. It will basically be used for hunting but I am the type if something is wrong fix it. One of the issues it has is that the AC/Heater will only work on none or high. I think it may be a resistor based on research, but since my research is old figured I would ask the group. Any pics of the fix would be appreciated. I am not sure how to access the resistor would be appreciated ...

Would try resistor

I ordered one of them from amazon. Any idea where it is located? Do I need to remove the glove box?
