where is the switch resistor on 2003 buick
I recently had to change mine...about a $25 fix. Kind of a pain to do but not bad. The blow motor resistor is behind the glove box. well i have a 2003 Chevy trailblazer ext but i assume they are the same. just empty the glove box...and it kind of forward and exposes the parts behind it. mine was to the left. hope this helps!
