The blower motor resistor (final stage) is utilized to control blower motor speed. It receives the driver demand signal from the HVAC control panel and sends a high current signal to control the blower motor speed. The blower final stage unit can fail resulting in a malfunctioning or inoperative blower motor. If you suspect your final stage is failing, look for the following symptoms:

  • Blower motor speed fluctuates from high to low.
  • Blower motor does not turn ON.
  • Blower motor only runs at one speed.

The blower motor final stage is located on the right side of the heater box, accessed from the center tunnel area.

The blower motor final stage is located below the right side dashboard at the transmission tunnel.
Figure 1

The blower motor final stage is located below the right side dashboard at the transmission tunnel. It installs into the HVAC heater housing. The green arrow points to its approximate location.

Working at the right side of the footwell, pull the carpet trim panel toward the front of the vehicle (green arrow).
Figure 2

Working at the right side of the footwell, pull the carpet trim panel toward the front of the vehicle (green arrow). When pulling the panel away, there are three trim panel clips (yellow arrows) that have to be disconnected.

With the panel detached, you can either leave the accessory outlet plugged in and lay the panel on the floor, or disconnect the electrical connector (green arrow) and remove the panel from the vehicle.
Figure 3

With the panel detached, you can either leave the accessory outlet plugged in and lay the panel on the floor, or disconnect the electrical connector (green arrow) and remove the panel from the vehicle. I always leave the panel on the floor. It is out of the way enough to access the final stage unit.

Next, disconnect the blower motor final stage electrical connector (green arrows).
Figure 4

Next, disconnect the blower motor final stage electrical connector (green arrows). To release the connector, squeeze the tabs on the sides of the connector and pull it away from the final stage.

Then, release the retaining tab (green arrow) by holding it down while sliding the final stage out of the HVAC housing.
Figure 5

Then, release the retaining tab (green arrow) by holding it down while sliding the final stage out of the HVAC housing.

Install the new final stage by pushing it into the HVAC housing until the release tab snaps into place.
Figure 6

Install the new final stage by pushing it into the HVAC housing until the release tab snaps into place. Check the blower motor function and confirm that it has the proper speed control.

  Followup from the Pelican Staff: We don't currently have that tech article. If we get a chance to perform the procedure, we will be sure to document it.

I would grab a repair manual. It will have the procedure, special tools and torque specs.

Give our parts specialists a call at 1-888-280-7799. - Nick at Pelican Parts

  Followup from the Pelican Staff: I don't understand the question. Pelican is Parts retailer. not a repair shop. Try a local repair shop if you need a mechanic. - Nick at Pelican Parts
