Blower Motor Resistor

This procedure covers the removal and replacement of the blower motor resistor, which controls fan speeds for the HVAC system in the 2015 Kia Forte.

Warnings

Tools required

Parts

• Blower motor resistor × 1 — Use OEM Kia part number or equivalent

Preparation

1. Park vehicle on level surface and engage parking brake
2. Turn ignition OFF and remove key from ignition
3. Allow HVAC system to cool if recently operated
4. Open passenger door for working access

Procedure

1. 1

   Remove lower passenger trim panel
   Locate the lower trim panel beneath the glove box on the passenger side. Use trim panel removal tools to carefully release the retaining clips securing the panel. Pull the panel away from the dashboard to expose the blower motor resistor area.
2. 2

   Locate blower motor resistor
   Using a flashlight, identify the blower motor resistor mounted on the HVAC housing. It will have an electrical connector attached and is secured by screws. The resistor is typically a rectangular component with cooling fins.
3. 3

   Disconnect electrical connector
   Press the locking tab on the electrical connector attached to the blower motor resistor and pull the connector straight off. Do not pull on the wires themselves. Note the connector orientation for reinstallation.
4. 4

   Remove resistor mounting screws
   Using a Phillips screwdriver, remove the screws securing the blower motor resistor to the HVAC housing. Keep these screws in a safe location for reinstallation.
5. 5

   Extract old resistor
   Carefully pull the blower motor resistor out of its mounting position. The resistor may have a foam seal or gasket that should be inspected. If the seal is damaged or deteriorated, it should be replaced with the new resistor.
6. 6

   Inspect mounting area
   Examine the mounting surface on the HVAC housing for debris, moisture, or damage. Clean the surface with a dry cloth if necessary. Check that the opening is clear of any obstructions.
7. 7

   Install new resistor
   Position the new blower motor resistor with its seal or gasket properly aligned. Insert the resistor into the mounting location, ensuring it seats fully against the HVAC housing.
8. 8

   Secure resistor with screws
   Install the mounting screws and tighten them using a torque wrench to the specified value. Tighten screws in a cross pattern if multiple screws are present to ensure even seating.

9. 9

   Reconnect electrical connector
   Align the electrical connector with the resistor terminals and push firmly until the locking tab clicks into place. Gently tug on the connector to verify it is fully seated and locked.
10. 10

    Reinstall lower trim panel
    Position the lower trim panel back into place and press firmly on all clip locations until each clip is fully engaged. Verify the panel is secure and flush with surrounding trim.

Reassembly

1. Ensure all trim panels are properly secured and aligned
2. Verify no tools or parts were left in the work area

Verification

• Insert key and turn ignition to ON position without starting engine
• Test all blower motor speed settings (low, medium-low, medium-high, and high) to confirm each speed functions correctly
• Listen for unusual noises from the blower motor during operation
• Verify airflow is appropriate for each speed setting
• Check that the blower motor turns off completely when switched to OFF position
• Inspect the work area for any air leaks or rattles from the trim panel
