2005 Pacifica... the front AC/Heater blower does not work at any speed, including high. I've tested the blower motor, and it is OK. Fuses and relay are both OK as well. The actuator that plugs into the bottom of the blower motor housing is getting power. Can it be the resistor even if the blower doesn 't work at any speed? If not, what else should I check. Thanks

 

blower motor resistor

 

OK, I just put a test light on the resistor, and one of the leads to the blower motor does light up. And, both of the screws on the bottom of the motor light up, so it is getting some sort of power. But, still, nothing works. Any change in diagnosis?

 

The wire at the resistor that does have power is dark blue...one of three leading to the resistor. I don't see where any other of the wires coming out of the component before the resistor cause the test light to come on.

 

One last thing. The plastic connectors with a lot of wires before the relay that I noted previously... when I open the connector, several of the leads from the switch DO light up (and blink). A couple do not. I have ordered a resistor. Am I still on target? The fact that both screws on the bottom of the blower fan motor cause my light to light up bothers me.

 

replace the resistor

 

I think that You will have need to get new resistor for your 2005 Pacifica. I have found more resistor, I have found Standard Blower Motor Resistor, You will get 3000 miles warranty over it. I am sure that It would be work very well than soon.
