How to replace Chevy Colorado blower resistor and plug
Chevy Colorados and basically all Chevy's always lose speeds on the blower. My truck had only high speed working and 1-2-3 would not work. After some research, it is the blower resistor and plug to it that commonly go out. Very very simple to fix, only tools I used were a 7/32 socket and wrench, wire cutters and wire crimpers, and some black tape. I bought mine off Amazon and instructions are included but it's very straight forward. Unplug, remove resistor with 7/32 socket, install new resistor and splice wires to new plug. What I did was splice one wire at a time because new plug wires are all gray so you can't just match them. Cut the very right one then splice onto plug and then move one wire over at a time. Good luck!!
Blower Not Moving Any Air
Many things can cause the A/C not to work right. Sometimes it's in the actual mechanical part of the A/C. And sometimes it's only in the "air movement" part of the system. If you are not getting any air blowing out the vents but the vents feel cold, AND you can hear the blower fan running, then it might simply be a restricted cabin air filter. Many Many people don't even know their cars have cabin air filters. And as these cars get older, the filters get more and more restricted. Even if yours isn't as restricted as this one, you should change them frequently.
