If the fan isn't working at all and you have checked the fuses, you would need to start tracing the wiring diagram and look at the various relays and follow test procedures for the resistor pack and blower motor and fan controls. 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.. 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 http://bit.ly/AllData_Repair_Manuals_Online

Ok patrick I have not checked the fuse but I moticed it has a 30 amp fuse and A HVAC Relay in the fuseblock could it be a that one of those could be bad? I dont want to go out and buy a new blower motor if it is not going to fix the problem? And how would I tell if that 30 amp fuse is bad? It is like rectangular shaped and it is blue.
