SOURCE: AC blower doesn"t run. pulled

2 things, either the blower motor resistor (most common problem controls the speed of the blower) or the wiring. 99% of th etime its the blower resistor $20-$50 and is mounted either directly to the switch control or behind the glovebox mounted to the blower housing itself

SOURCE: where is the blower motor?

This work for 1998 Buick Century 3.1L SFI OHV 6cyl; the blower motor is a variable speed motor. The higher the voltage applied to the motor, the faster the speed. Depending on the HVAC (Heater Ventilation Air Conditioning) option installed in the vehicle, blower speed control could be through a set of resistors or through a solid-state blower motor control module.

In general, this system is reliable. Because so many of the control operations are electronic, special diagnostic equipment really should be used for system diagnostics and check-out. An authorized technician using a scan tool can most quickly locate HVAC problems.

Fig. Typical HVAC operation schematic

An inoperative blower motor could be caused by the following:

* Blown fuse(s). The fuse should be replaced. There may be both a LOW BLOWER and HIGH BLOWER fuse. Some models may also call it the HVAC fuse. Even the RADIO fuse is used in some applications. Check them all. If a fuse is blown there may be a short to ground in one of the power supply circuits.
* Open Circuit. Check the circuit between the ignition switch and the blower motor, and the blower motor ground circuit. Repair as necessary. * Faulty blower switch. A faulty blower switch should be replaced. * Most heater blower circuits also include a blower motor relay (look in the underdash convenience center), as well as a blow motor resistor. These items should be checked especially if the blower runs in one or two speeds, but not all speeds selected.

REMOVAL & INSTALLATION

  1. Disconnect the negative battery cable.
  2. The blower motor is located on the passenger side of the vehicle, under the instrument panel. Remove the right side sound insulator (trim panel) by removing the retainers and disconnecting the courtesy lamp.
  3. Detach the blower motor electrical connector. Some applications may have cooling hose to the motor which should be disconnected.

Fig. Blower motor and fan assembly removal

  1. Unfasten the blower motor mounting screws, then remove the blower motor from the vehicle.
  2. If the blower motor fan (also called a 'squirrel cage') must be replaced, use the following procedure:
NOTE Do not hammer on the motor to remove or install the fan. Do not apply force to the motor housing to seat the fan on the motor, or motor/shaft bearing damage could result. Do not apply pressure to the fan rim. Be sure the correct replacement part is used.
  1. Remove the metal star clip retaining the fan cage to the motor shaft.
  2. Remove the fan by pulling straight out.
To install:
  1. If removed, install the blower motor fan, as follows:
    1. Install the replacement fan cage onto the motor shaft.
    2. Adjust the fan cage to get a clearance of 0.30 inch (7.5mm) to the motor mount plate.
  2. Install the remaining components in the reverse of the removal procedure. Make sure the electrical connection is secure. Tighten the motor screws to 14 ft. lbs. (20 Nm).
  3. Connect the negative battery cable, then test the blower motor for proper operations


I hope this helps (remember to rate and comment this answer).

2000 kia sportage, blower fuse location


Let's start with the passenger compartment fuse box. If you checked the 30A HEATER fuse the blower motor should run at various speeds as you operate the blower switch. If you checked the 10A REAR WIPER fuse (!), and also checked the 30A ADD (?) fuse in the engine compartment fuse relay box, turning on the air conditioner should operate the A/C relay to turn on the condenser fan motor. If this doesn't solve your problem, you'll have to trace power through the various circuits.

2004 CHEVY SUBURBAN FRONT A/C WORKS BUT THE REAR DOESN'T TURN ON


There is a blower motor control processor for the back blower - it takes input from the front control and the rear control and decides the fan speed. That processor could be faulty, or the blower motor, or a 30amp fuse in the engine compartment.
In the front system you have a controller and blend doors that direct air thru the heater core and evaporator. You would need to check the operation of those blend doors.

1996 GMC Sierra Heater blower motor only works on high speed. How do you change resistor?


The blower motor resistor is located within a foot of the blower motor in the duct that the blower motor blows into. The resistor is actually cooled off by the blower motor blowing across it. It has a wire harness that connects it to motor & fan switch. It is held in place by 2-4 retaining screws. Disconnect wire harness,unscrew retaining screws then lift out. Reverse order to install.

MY AC/HEATER DOES NOTHING WHEN YOU TURN IT ON. IT DOESNT BLOW AT ALL.


While parked with the hood raised, start the engine and turn on your a/c. Check to make sure your cooling fans are running. If they are, I would look into the blower motor for the passenger compartment blower. This is what causes the air to enter the vehicle. You could have a damper door that is not allowing it to blow into the passenger compartment as well.
