There's only one line going out of the resistor box to the motor. You're maybe right, it could be that this line is cut.

SOURCE: Replacing Blower Motor Resistor

  1. Disconnect and isolate the battery negative cable.
  2. Open the glove box.
  3. Flex both sides of the glove box bin inward near the top far enough for the rubber glove box stop bumpers to clear the sides of the glove box opening, then roll the glove box downward.
  4. Reach through the glove box opening to access and disconnect the instrument panel wire harness connector for the blower motor resistor from the resistor connector receptacle (Blower Motor Resistor).
  5. Reach through the glove box opening to access and disconnect the blower motor pigtail wire connector from the resistor connector receptacle.
  6. Remove the two screws that secure the blower motor resistor to the evaporator housing.
  7. Remove the blower motor resistor from the evaporator housing.80ac4e54.gif

SOURCE: Lincoln 2000 town car Blower doesn't work at HI-MED-LOW speeds...

it is called blower motor resistor , should be close to blower motor , you will see a plug type connector with two screws , remove the screws and there should be a resistor inside the cover for the motor, swap with new and reassemble

SOURCE: Blower motor vent selection switch not working

the hvac selector switch in the dash may be the problem.You need to remove the switch and look at the connector on the back of switch,see if there are any burnt wires at the connector or switch.It's all electronic and the switches have been known to burn out on this and other model.

2004 crown vic. only 63K miles on her. AC/heat fan was sporadically working, now its done. AC was nice and cold, working fine. Is the fan a hard replacement if I were to find one at a parts yard?


Try to check the power and ground on the blower fan. If you missing the ground on the blower fan connector than most likely it is the blower fan resistor (controller), it is located under the hood close to back firewall behind left cylinder head.

Blower Motor/Fuse


On Nissan vehicles, the blower motor gets power from the fuse box, and the resistor and fan speed control provide the ground circuit.
So you should be able to ground the motor and make it run if you have power going to it. Then you would need to check the resistor and fan switch. The high setting bypasses the resistor.

If the 30amp blower fuse has power, and you can run power to the blower motor and it runs, I would say its the blower relay or the control switch on the dash. The control switch provides power to turn the blower relay on. The fan switch provides the ground circuit.

Blower motor


I'm showing a blower relay and a resistor used on models with manual ac control.
The blower motor is grounded and the fan switch provides power thru the resistor. So you have a 40amp blower fuse that handles high thru the relay, then a 30amp HVAC fuse that powers the blower thru the fan switch.
Do you not have power from the resistor to the blower motor on the purple wire ?

01 grand.prix ac fan switch only works on high. has a duel temp controller when you turn fan off the only way fan comes back on is to move the temp controller levers


Hi!!
When the Blower Motor Resistor (controls blower speeds) goes bad, the blower motor works only on HIGH SPEED. REPLACE IT.
BLOWER MOTOR RESISTOR Removal & Installation
  • Disconnect negative battery cable.
  • Remove right lower instrument panel insulator panel.
  • Disconnect blower resistor connector located behind right side of dash.
  • Remove blower resistor screws and blower resistor.
To install, reverse removal procedure
Good Luck!! A HELPFUL - 4 THUMBS - rating for this solution would be greatly appreciated. Thank you for using FixYa!!

have you replaced the blower motor resistor yet,it is a printed circuit that has a floating ground.it is where the blower motor wires plug in to.if you unhook the motor wires and use your ground and hot wire on the motor it should test normal,

Check the blower motor speed control resistor pack is ok.
(The resistor pack is usually located in the blower fan ducting in the air flow).
Check condition of electrical connection terminals on the blower motor circuit - these terminals pass considerable current and over time may fatigue overheat and loosen.
Check operation/replace any blower motor control relay,
Check the blower motor will run if +12v directly applied to the blower motor.
Check operation of the blower motor speed control switch is ok.

Blower motor doesn't work and has no power to it


Check the blower multispeed control resistor pack is not faulty.
The resistor pack is usually located in the air ducting, in the blower fan airflow.
Basically, +12v power is supplied (via fuse) to the fan speed control switch, which then passes via the selected speed control resistor, to the fan motor. Often a interface relay is used to switch the blower motor high current.

Fan on High Only


The fan motors use a set of resistors to control fan speed. The lower speeds generate more heat in the resistors and these tend to burn out. While it is possible the switch could be the issue, I would start with the resistors. It is usually a module located somewhere near the blower motor.

Note: One of the reasons these go out, is that with time the bearings on the blower motor go bad and the motor takes more power to run. If the replaced resistors fixes the problem, but then fail too soon, look at replacing the blower motor as well.

Check or have checked the blower motor resistor. This is usually how they act.
