If the blower is completely dead and is not providing any air movement, the cause could be in the resistor block for the fan motor or the fan motor.

1.- If you have one or more blower speeds, the problem is the Resistor Block. This part (resistor block) controls the various speeds of the blower motor. It is located on the passenger compartment side of the blower housing and can be replaced in few minutes. You can find the part online for around $10.

2.- If you do not have any speeds, you should verify the Fan Motor works by pulling it and connecting it to a 12 volt DC power source. To pull the fan motor, you will have to remove the glove box to gain access to the 3 or 4 screws that hold the fan in place, although I did it without removing the glove box. The motor is attached to a large mounting plate that is at the bottom of the air plenum located behind the glove box. If you look up from the passenger floor you will see the motor hanging down. Once the connector is disconnected and the screws are out, you will have to turn the mounting plate to allow the motor to drop. Keep in mind the position as you pull it down as it needs to go back in the same twisting fashion.

    Check the Temperature Control Cable - REMOVAL & INSTALLATION
    1994
    Utility Models





    1. Remove the control panel assembly from the instrument panel.


    2. Remove the radio.


    3. Unfasten the cable retainers, then disconnect the cable from the
      control assembly and the heater module.



    4. After all the control cable retainers and clips have been removed
      or disconnected, remove the cable.



    To install:



    1. Install the cable making sure it is routed correctly.


    2. Attach the control cable to the control panel and the heater
      module.



    3. Install all remaining cable retainers and clips.


    4. Install the radio and control panel.
    Good luck.

Engine cold. Start engine reading says engine hot ac off. Fans run all time.


Are the fans running on low or high ?
Circuit/System Description
The engine control module (ECM) commands the fans ON in either high speed or low speed, depending on cooling requirements. In low speed, both fans are turned ON at a reduced speed. High speed has both fans turned ON at full speed.
In low speed operation, the ECM applies ground to the coil side of the fan low relay. This energizes the coil and applies voltage directly to the left cooling fan through the switch side of the fan low relay, which is fed by the fan 1 fuse. The right fan is connected in series to the left fan through the de-energized fan control relay so that both operate at low speed.
In high speed operation, the ECM applies a ground to the coil side of the fan low relay, the fan control relay , and the fan high relay. On the fan high relay, the energized coil closes the switch side of the relay and applies voltage directly to the right cooling fan through the switch side of the relay, which is fed by the fan 2 fuse. At the same time, the ECM energizes fan control relay pulling the switch side over, providing a direct path to ground for the left cooling fan, which has voltage applied through the energized fan low relay. In high speed mode, the fans are operated as a parallel circuit with full voltage applied to each.
You should have it hooked up to a scan tool that can read engine sensor data parameters . Check for DTC'S - diagnostic trouble codes etc...
Circuit/System Verification
  1. If DTCs P0480 or P0481 are set, perform those diagnostics first.
  2. Ignition ON, verify with a scan tool that the control module is not commanding fan activation.
  3. Ignition ON, observe that the fans are not activated.
Your best bet is to take it to a ASE certified repair shop !

Blower motor works only on hight speed


Most heater fans have a resister built into the wiring and connection block on the actual casing. High fan speed=full voltage, Mid speed=small resister, Slow fan speed=large resister. Change the resister block. Pete

2007 Suzuki Forenza ac/heater/defrost fan not working


the cab heater fan?, there can be 4 fans on some cars.
front condenser, 2 on rad, and 1 in cab heater box.
the cab fan? does it fail on high too?
it has a switch, (marked fan speed)
the switch is bad ,if low speed are dead. and high are good.
or wiring to it , the motor or the fuse.
even a cracked fuse, change the fan fuse to a new fuse.

1992 chevy C1500: Heat works on low speed, no medium, and high only works intermittantly.


On any other vehicle it sounds like the blower fan switch.
The fan switch provides power or ground to the resistor and there would be a high speed blower relay to bypass the resistor.
But in your case the fan switch is part of the controller.
I don't have a diagram for a 92 but the 94 model shows relays for low medium and high speeds. Each relay gets power from a fuseable link. The high relay gets power thru the low relay if the low relay is not engaged.
If you have the model with 3 relays you may need to check them.

The ac is on full at all times, even when you adjust the fan hight. someone sayed i need a a/c auto amplifier. but i can't find that part


Good Evening, If I am translating this properly your fan only works on the high setting? And the other settings do not change the speed? If this is correct respond back and I will help as much as possible.

Heat/ac fan only blows on high


Check the heater control switch,,,,,and the number of wires at the heater motor....Some motors have more than one winding...in which case there will be three or more wires going into motor..there can be burnout in those windings and will require a new motor....check the plug which attaches to the motor....can be bad connection...or at the switch.....but if there is only two wires....then the heater switch uses resistors to slow down the different speeds...and direct connection for high speed....and the problem is definitely the switch...

Heater & cooling fan only works on high.Power locks don't work.


there is a resistor for the heating and cooling fan speed. this controls the amount of voltage to your fan, which controls the speed. usually when the fan only works on high it will bypass the resistor and use the full 12 volts for the high setting. your power locks might be part of this circuit. i would check the resistor first then check the locks. usually the resistor is behind the high low switch

Location of low speeds heater fan fuse & switch. I do not have a owners manual.


the switch is on the dash with the other a/c controls. does the fan work at all? high speed OK? but the lower speeds dont work? if any speeds other than high dont work, replace the blower resistor.

No low speed heater fan, only high speed works


BLOWER MOTOR RESISTOR IS BAD . HI SPEED IS DIRECT POWER BUT ALL OTHERS GO THROUGH RESISTOR
