doesn't matter what setting or anything at all. the only thing that comes out of vents (all vents no control over defroster or floor or panel vents) is a cool breeze makes it near impossible to drive in cold weather cause defroster doesn't work. help
Climate control does not work. on 2002 Oldsmobile Bravada
it could be blower motor or blower resister or poss wiring at resister,this is the most common on this year gm
Thank you. I appreciate your insight

does your blower motor work?
nothing turns on. i do believe its the blower motor bcuase of the fact it that even if its switched off it still blows out a light cool air out of all vents.
