Blower motor doesn't work, how do I find out if its the fuse, relay or if the motor itself is shot? I know where the fuse box is but some of it is abbreviated and I don't know what some of it stands for....


The blower motor can be tested by removing the lead to it and seeing if it has 12 Volts by observing if the 'test light' lights up when the dash controls indicate that the blower motor should be operational.

One can test the fuses by using a 'fuse tester' available from Walmart or an auto parts store which will light up when an energized circuit has a blown fuse.

The blower motor is located on the firewall on the passenger side, in general on GM cars from the 1990s.

You may have to remove some items to get to it, though.
Blower Motor REMOVAL & INSTALLATION
  1. Disconnect the negative battery cable.
  2. If necessary, tag and disconnect the number 2, 4 and 6 spark plug wires from the ignition coil and move the coil out of the way.
  3. For 1993-99 vehicles, remove the nuts and cross brace bar.
  4. Detach the electrical connections from the blower motor.
  5. Disconnect the cooling tube from the blower motor.
  6. Unfasten the screws securing the blower motor to the blower module assembly.
  7. Remove the blower motor and fan assembly from the module.
  8. If necessary, unfasten the nut attaching the fan to the blower motor shaft, then pull the fan from the blower motor. Fig. 1: The blower motor and fan assembly is mounted in the heater and A/C module, and is accessible from the engine compartment 89636g22.gif
    Fig. 2: You can disassemble the fan from the motor by removing the retaining nut 89636g23.gif
    To install:
  9. If the fan was removed from the motor, position the fan on the shaft, then install the retaining nut. Tighten the nut to 12 inch lbs. (1.4 Nm).
  10. Position the blower motor and fan assembly to the module, then install the retaining screws. Tighten to 5 inch lbs. (0.6 Nm).
  11. Connect the cooling tube to the blower motor.
  12. Attach the electrical connector to the blower motor.
  13. On 1993-98 vehicles, install the cross brace bar and retaining nuts. Tighten the nuts to 18 ft. lbs. (25 Nm).
  14. If removed, install the coil and connect the spark plug wires, as tagged during removal.
  15. Connect the negative battery cable.

Where is the blower motor? heater in car dosent blow. not under hood, cant get through glover compartment.


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.

zjlimited_78.jpg

Fig. Typical behind-the-instrument panel view of HVAC related components. Depending on the HVAC option, not all components are used on all vehicles (click for zoom)

zjlimited_79.jpg

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).

My 1988 Ford Tempo's heater fan is not working. I can feel heat at the windshield vents,but the fan wont come on. I have jumped the fan speed switch with a paper clip--and blew a fuse--and checked the...


your circuit is simple--I will paste it below. suspect the blower has shorted and caused the switch to burn up. remove the blower and hotwire it to the battery to see if it works. If not, replace the blower. Then run continuity tests on the swoitch and replace switch if bad. If you have questions, please let me know. Here is procedure for taking blower out:


REMOVAL & INSTALLATION With Air Conditioning

  1. Disconnect the negative battery cable.
  2. Remove the glove compartment door and glove compartment by removing the retaining screws and bolts. Push the sides of the glove box in to free the drawer from dash panel.

  4. Remove the retaining screws securing the ducting around the blower motor.
  5. Remove the clip securing the blower motor fan blade to the motor arm. Remove the fan blade from the motor.
  6. Remove the blower motor mounting plate from the evaporator case by unscrewing the retaining screws.
  7. Rotate the motor until the mounting plate clears the edge of the glove compartment opening and remove the motor.
  8. Remove the wire harness from the rear of the motor.
  9. Inspect the fan blade for broken edges or cracks. Replace if needed.

To install:
  1. Connect the wire harness to the rear of the blower motor.
  2. Install the motor into the case and secure with the retaining screws.
  3. Position and fasten the fan blade to the blower motor arm. Secure with the clip.
  4. Secure the blower motor outer housing to the duct assembly with the retaining screws.
  5. Install the instrument panel at the lower right hand side if removed earlier.
  6. Install the glove compartment door and glove compartment.
  7. Connect the negative battery cable.
  8. Run blower motors to make the motor works correctly.
Without Air Conditioning
