This article applies to the Dodge Ram 1500 2nd Generation (1994-2001).

Speed is something associated with the engine and transmission, among other things, but one component's speed that sometimes gets taken for granted is the cabin's fan, or blower for the A/C and heating system. The blower motor produces a circulating motion to force air into the cabin that's crucial for the A/C or heating system to keep your truck's interior temperature regulated and comfortable. Sometimes, however, the blower goes out due to wear and tear, or electrical damage. Thankfully, replacing the blower motor is a simple DIY task—here's how.

Materials Needed

  • Phillips screwdriver
  • 8mm socket
  • Ratchet and extension
  • Lubricant (if necessary)

Step 1 – Disconnect the wire harness and hose

  • Always disconnect the negative battery terminal (black) before working on electrical components. Safety first!
  • Then head to the front passenger's side foot well, and look underneath the dashboard where the blower motor is located.
  • The motor has a power supply wire harness routed through the front of it and high up beneath the dash. Reach up with your hand, pull back on the tab of the harness connector, and then unplug it.
  • On the left side of the blower motor, there is a small rubber hose connection. Simply pull the hose out from the motor by hand.

Step 2 – Remove blower motor

Once the wire harness has been disconnect and the rubber hose unplugged, there are only three bolts holding the blower motor up.

  • Use a Phillips screwdriver or ratchet with 8mm socket to remove the three mounting bolts. You may need to switch between the two tools if the bolts are difficult to remove.
  • Once you've removed the bolts, the blower should gently slide down and out of place.

Pro Tip

If the old blower motor is running slow and squealing, you might be able to repair it. Once you've removed the motor, unbolt the fan and spray lubricant onto the bearing. Then, re-install the fan and rotate it to make sure it turns more freely.

Step 3 – Install the new blower motor

Re-install the blower motor in reverse order to the steps above, and make sure all bolts and connections are tightly secure.

  • Set the new blower motor in place under the dash.
  • Secure the motor with the three bolts.
  • Connect the wire harness and rubber hose.
  • Reconnect the battery.
  • Finally, start your truck and turn on the fan to test the new motor.
