Question about 2003 Chevrolet Malibu

Heater Blower not functioning

Heater blower motor went out and will not operate on any setting. This is a recurrence of problem. Previously removed blower motor and tested. The process of removing and testing seemed to fix problem. The blower was working on all speeds. Therefore, I believe the motor and speed resistor are ok. I am really confused.

SOURCE: 2004 Chevrolet Silverado Heater/AC Blower on without Ignition ON

there is no relay for the heater fan it's a 15 amp fuse and is on the accessories circuit. the reostat is responsible for all 3 speeds .with the key off there should be no voltage to the blower motor whether the fans speed fan switch is on or off. the fuse will be located in the fuse paneleither on the drivers left side in the dash or underneath the dash in the fuse block. you have a short in the harness that is under the dash and most likely it's a bad plug on the harness. your going to have to do some searching but that's where the problem short is... please rate

SOURCE: Blower motor or resistor?

Yes its the blower motor resistor.

More then likley theres some trash or something in it, or possibly the motor itself is on it's way out. There not that bad to pull out of that body car, just pull it out and see what you can see.

The blower motor is under the glove compartment

You can replace the resistor on your own. Please find a detailed diagram which would guide you to do it.

SOURCE: heater/ a/c blower motor only

It is a blower resistor set. This resistor set regulates current which gives you the various fan speed settings. Depending on the vehicle it is located under the dash on either passenger or driver's side.

SOURCE: Blower motor or resistor?

If it was the motor that went out then it would not blow at all. The resistor is the culprit that starts killing off speeds. It should be about $25 to $30 at an aftermarket store like autozone or advanced auto parts.

Pinpoint Test Q: The Blower Motor Does Not Operate Correctly - EATC
Normal Operation Under normal operation, the blower motor control module receives a 1-2 volt signal from the EATC module through circuit CH218 (GN/VT) to determine the desired blower motor speed. The EATC module receives a feedback voltage from the blower motor control module through circuit VH219 (GY) to determine actual blower motor speed. When the highest blower motor setting is selected, the EATC module sends 12 volts to the blower control module through circuit CH217 (BN).
    Possible Causes
  • An open, short to voltage, ground or together in circuits CH218 (GN/VT), VH219 (GY) or circuit CH217 (BN)
  • Blower motor control module
  • EATC module

The heater fan on my 1993 f-350 has become really loud. I only have hi speed which I understand may be a resistor issue but how do I remove the fan and motor assembly to inspect it?


A heater blower motor resistor is an electronic device with three or more progressive resistors that allow the heater blower motor to operate at slower speeds. The highest speed of the heater blower motor is not controlled by the resistor, so when the resistor fails, the fan will often work on the highest speed setting, but not the lower speeds.
To resistor is generally located under the dashboard and under the hood, near the blower motor . The resistor's electrical connector is disconnected, the resistor is removed and the new resistor is installed. On some vehicles it may be easily accessible, and on others it may take partial dashboard removal to replace the resistor.
Look under the hood, generally the wiring for the Blower resistor is attached to the wiring to the blower motor itself
It's inboard & below the motor, near the accumulator. You can see it standing beside the passenger fender. it's the off-white connector behind the L heater hose above the vacuum reservoir & the white WARNING sticker

Where is the heater motor


You can get to it from the engine compartment, but you have to cut the cover off. There is an indented line showing where to cut. See picture below.

  1. For the 3.1L engine, remove the alternator belt, then remove the alternator and position aside.
  2. For the 2.5L and 3.3L engines, remove the power steering pressure hose from the power steering pump.
  3. For the 3.0L engine, remove the serpentine belt.
  4. For the 3.0L and 3.3L engines, remove the retaining bolts from the power steering pump bracket, then set the pump aside.
  5. Detach the blower electrical connector, then, if accessible, remove the cooling tube.
When cutting the blower motor cover, make the cut just the thickness of the cover, which is1/ 8 inch (2mm) thick. Cutting deeper than that may damage the cooling tube.

For 1992-98 vehicles, partially cut the blower motor case cover, as shown on the cover. Cutting completely around the cover is NOT required. Swing the cut potion of the cover down.



jturcotte_357.gif

  1. If previously accessible, disconnect the cooling tube.
  2. Unfasten the attaching screws/bolts and remove the blower motor from the case.
  1. If necessary, remove the fan from the blower motor.
  2. The installation is the reverse of the removal procedure.
  3. If the case was cut during removal, secure the cover using the three retaining clips. Tighten the blower motor screws to 44 inch lbs. (5 Nm).
  4. Connect the negative battery cable, then start the engine and check the blower motor for proper operation.

No, but it isn't too hard to get to under dash. I will paste instructions from autozone.com below. Pictures may not come thru.

CAUTION The Supplemental Inflatable Restraint (SIR) system must be disarmed before removing the blower motor assembly. Failure to do so may cause accidental deployment of the air bag, resulting in unnecessary SIR system repairs and/or personal injury.

How do you replace the blower motor on 92 accord wagon - where is it located?


Disconnect the negative battery cable (if you have an anti-theft radio, make sure you have the code).
The blower unit is located in the dash, behind the glove box.
Remove the glove box and the glove box frame(damping screws on the sides and two screws underneath).
If the car isn’t equipped with air conditioning, remove the heater duct between the heater core and the blower assembly housings. Then remove the three blower housing retaining nuts, pull the blower housing out far enough to unplug the electrical connectors (at the lower right edge, right above the kick panel) and remove the blower assembly housing.
If the car has air conditioning, remove the strap bolt, the blower under cover and the three blower housing retaining nuts, then remove the blower assembly as previously described.
If you are replacing the blower motor itself, or either of the blower fan wheels, remove the motor, remove the retaining clip(s) and remove the fan wheel(s).
Reverse procedure to install.
Hope this helps you.

Air conditioner/heater blower fan on 1997 Buick Riviera not working. Regardless of whether it's on ''Auto'', Vent, Recirc, or Front Defrost button setting, even though I can see the fan level meter going...


it will be hard to diagnose with out having my hands on it but try this.

this vehicle is known for blower motor resistor failure.

under the dash on the passenger side next to the blower motor there is a resistor attatched to the blower motor case it will have a single plug with 5 or 6 wires in it, they are normally within a couple of inches of the blower motor, remove this resistor and look at closely for any signs of burning this is a common problem, you can buy one at any parts house, do not operate the motor with the resistor removed from its mounting hole or you will damage it.

if the resistor looks good than purchase you a test light and drop me a line and i will explain how to test the entire system its not hard to do.
