Tools required

Parts

• Front power window regulator assembly × 1 — Use OEM specification
• Door panel retaining clips (if broken) × 1 — Use OEM specification
• Window run channel felt (if damaged) × 1 — Use OEM specification

Preparation

1. Disconnect negative battery cable to prevent accidental power window operation.
2. Roll window to approximately mid-position for easiest access to regulator bolts.
3. Park vehicle on level surface and ensure adequate lighting inside cab.
4. Gather all tools and replacement parts before beginning disassembly.

Procedure

1. 1

   Remove window crank handle or switch assembly
   If manual windows are present (non-power), remove window crank handle by prying out the retaining clip behind the handle with a flat-blade screwdriver. For power windows, pry out the power window switch bezel using a trim tool and disconnect the electrical connector by depressing the locking tab.
2. 2

   Remove door panel retaining screws
   Remove the 3 Phillips screws securing the door panel: one in the armrest area, one in the door pull cup, and one near the bottom rear corner of the panel. Some models may have an additional screw near the door latch.
3. 3

   Remove door panel
   Insert door panel tool or flat trim tool between panel and door frame at the bottom edge. Work around the perimeter to release the 8 retaining clips. Lift panel upward to disengage from upper door frame lip, then pull away from door. Disconnect any remaining electrical connections for courtesy lights or speakers.
4. 4

   Peel back moisture barrier
   Carefully peel back the plastic moisture barrier sheet from the door inner panel. If the barrier is glued, work slowly to avoid tearing. You may need to reapply adhesive during reassembly if original adhesive loses its bond.
5. 5

   Support window glass
   Raise window glass to the full-up position. Secure the glass in place using masking tape from the glass to the outer door frame, or have an assistant hold the glass. This prevents the glass from falling once the regulator is disconnected.
6. 6

   Disconnect power window motor
   Locate the power window motor electrical connector inside the door cavity. Depress the locking tab and disconnect the connector from the motor. On some models, you may need to access this from the rear of the door cavity.
7. 7

   Disconnect glass from regulator
   Locate the 2 bolts connecting the window glass to the regulator lift channel through the access holes in the inner door panel. These are typically 1/2" bolts. Remove both bolts and carefully slide the glass upward and out of the regulator channel. Ensure glass remains secured in the up position.
8. 8

   Remove regulator mounting bolts
   Remove the 4 bolts securing the regulator assembly to the inner door panel using a 7/16" socket. These bolts are located at the front, rear, and center mounting points of the regulator track. Note the position and orientation of any spacers or washers.
9. 9

   Remove regulator assembly
   Tilt and rotate the regulator assembly to maneuver it through the large access hole in the inner door panel. The regulator track and motor assembly must be angled carefully to clear the door frame. Remove the complete assembly from the door cavity.
10. 10

    Install new regulator assembly
    Position the new regulator assembly inside the door cavity. Angle and rotate the assembly through the access hole in the same manner used for removal. Align the regulator mounting holes with the corresponding holes in the inner door panel.
11. 11

    Install regulator mounting bolts
    Install the 4 regulator mounting bolts with any original spacers or washers in their original positions. Tighten bolts in a cross pattern to ensure even mounting pressure. Hand-tighten firmly but do not overtighten to avoid stripping the door panel threads.
12. 12

    Reconnect glass to regulator
    Remove tape or support from window glass. Lower the glass down into the door cavity and align the glass mounting holes with the regulator lift channel. Insert and tighten the 2 glass-to-regulator bolts through the access holes. Ensure glass sits squarely in the channel.
13. 13

    Reconnect power window motor
    Reconnect the electrical connector to the power window motor, ensuring the locking tab clicks into place. Temporarily reconnect the battery negative terminal to test window operation before final reassembly.

Reassembly

1. Test window operation through full up and down travel before reinstalling door panel to ensure proper regulator function and glass alignment.
2. Reposition moisture barrier sheet on door inner panel, using fresh adhesive if necessary to ensure proper seal.
3. Reinstall door panel by engaging upper lip first, then pressing firmly around perimeter to seat all retaining clips.
4. Install all door panel retaining screws and tighten securely.
5. Reconnect power window switch and install switch bezel, or reinstall window crank handle with retaining clip.
6. Test window operation one final time to verify smooth travel with no binding or unusual noise.

Verification

• Window should operate smoothly through full travel range without binding, hesitation, or abnormal noise.
• Glass should align properly with door frame and weatherstripping at full-up position with no gaps.
• Window should stop at full-up and full-down positions without motor strain or clicking.
• Door panel should be firmly seated with no rattles or loose clips.
• All electrical connections should be secure with no exposed wiring.
