Thanks for asking Just Answer.There is 2 wires that go to the blower motor,one should have power and the other no power.If they both show power with it still connected,then you most likely have a bad blower speed controller.It is located in the evaporator housing near the RH side of the engine.It`s a bit of a pain to change if you have never changed one before,just not alot of room to work.I hope this helps.

You can check the blower motor with either a volt meter or a test light.With the key on and the a/c on,check both wires at blower motor one at a time.With a meter,connect the red lead to blower motor and the black lead to ground.You should read at least 10 volts on one wire and almost 0 on the other.If you show more than 10 volts on both the blower controller is most likely the problem.When I said RH side,that is the passenger side.I hope this helps.

I don`t have any pictures available to send.I will try to explain where it is.Standing in front of the car you will see the blower motor to the left,inside the housing it bolts to is where the evaporator is ( this is what the refrigerant lines hook to ) on the other side of the evaporator housing is where the blower controller is.Right behind the valve cover on the passenger side.It has 2 bolts that hold it to the evaporator housing and has 4 or 5 wires going to it.I hope this helps.
