Have you checked fuse #19 (30 Amp)see that you have power at the green/black wire at the motor with the key on, the second wire gets grounded to operate the blower motor but you need a wiring diagram to trace the controls circuit. Autozone have some popular workshop manuals for free on line once you register (for free) on their website There is a company that independent auto repair shops get their information from, this same information is available inexpensively for people that work on their own cars.. The information is year make and model specific, covering repair procedures, torque specifications, fluid capacities and specifications, service bulletins, component locations, wiring diagrams ect.... Alldata is very easy to navigate
