When I first purchased my car it had no heat or air from the fact that it didn't have the blower motor in at all. After buying a new blower motor and finding pieces of what was left of the original fan I'm my heater core i am now not getting any power to the blower motor. I checked the other wires coming from that same set if harnesses behind the glove box and they all check out good, all getting power. If anyone could point me in the right direction of how to fix this that would be cool. Thanks.

-Check your fuses. Often they look good but are blown right at the edge of the element where it is hard to see.
-The blower motor runs of a variable voltage Relay. That's the 2nd place I would check if you are not getting any voltage at the blower motor connector make sure the relay is functioning and you are getting power to it.
-The circuit that controls the Relay connects to the climate control pod. Make sure that's functioning right and its getting power. I don't know anything about the automatic system so I am not sure what else you need to check on those but I do know they have temperature sensors.

Hope this helps
