Blower Motor - REMOVAL & INSTALLATION

This procedure is applicable for vehicles, with or without air conditioning.

  1. Disconnect the negative cable at the battery.
  2. On the 3.1L (VIN M) you will need to remove the serpentine belt and move the alternator aside.
  3. For the 2.2L (VIN 4), disconnect the air inlet resonator, then remove the torque strut from the engine. Rotate the engine slightly forward.
  4. Working inside the engine compartment, disconnect the blower motor electrical leads.
  5. Remove the motor retaining bolts. If there is a hose disconnect it, then remove the blower motor.
To install:
  1. Position the blower motor on it's mount.
  2. Install the mounting bolts and tighten until snug.
  3. Attach the drain hose if removed, then engage the electrical connection to the motor.
  4. On the 2.2L (VIN 4), properly position the engine and install the torque strut to the engine. Connect the air inlet resonator.
  5. On the 3.1L (VIN M), install the alternator, if removed. Install the serpentine belt.
  6. Connect the negative battery cable, tighten the cable bolt to 11 ft. lbs. (15 Nm).
  7. Reset the radio, clock and any other applicable electronic devices.

Heater fan not working


Smack it and see if it comes on. If it does then the motor brushes are bad. If it does not come on, check the fuses. If the fuses are ok, check the voltage on the plug to the motor.

I have only high speed on my ac/heat switch. have replace acdelco blower motor resistor 2 times already. works for a while and quits. whatelse do I need to check etc?.


If you have replaced the blower motor resistor block twice all ready, i would be replacing the blower motor itself. When the blower motor is drawing too much current it burns out resistors for lower fan speeds in resistor block, but doesnt blow fuse for fan. Also check for leaves and stuff in fan when removing fan.

Hi, should be listed as heater blower motor not fans ,the fans is the ones in front of radiator. most common problems are the blower motor resistor, which is in passenger side compartment near fire wall.This is were your blower motor is also. You can check and see if its getting power to resistor, with a test light if power is at resistor, check and see if you are getting power at blower motor if no power there replace resistor. But if you have power at motor replace blower motor. If i can help further just re post. thanks

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.
