Blower Motor Resistor '02 Trailblazer

Setting 1 and 5 won't blow, 2-3-4 works find.

my extended warranty won't cover replacement. I think I can replace myself.

where is it located in a 2002 trailblazer. does anyone have a document or procedure of manual I can reference.

part # of what I need is 15415789 cost is about $23.

Thanks

Chewie
