    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 http://bit.ly/autozone_repair_info. 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..
