Warnings

Tools required

Parts

• Front power window motor × 1 — Use OEM specification or aftermarket equivalent for 1972 F-100
• Door panel clips × 1 — Replace any broken clips during removal
• Wire connectors or butt splices × 1 — If splicing wiring
• Pop rivets × 1 — 1/8 inch aluminum rivets if motor is riveted

Preparation

1. Park vehicle on level surface and engage parking brake
2. Disconnect negative battery cable
3. Roll window to approximately halfway position before disconnecting battery if motor is functional
4. Lay out a blanket or towel to protect removed door panel

Procedure

1. 1

   Remove door panel hardware
   If a manual crank handle is present, remove it by prying out the trim clip behind it with a flat blade screwdriver and pulling the handle off. If the door uses power window switches, carefully pry the switch bezel/panel free and disconnect the switch harness instead. Remove the interior door handle escutcheon screws (typically 2 screws). Remove armrest screws if equipped (typically 2-3 screws along the bottom edge). Remove any visible screws around the perimeter of the door panel. Verified detail (No OEM power window motor part number exists for the 1972 F-100 because it had no factory power windows. Any OEM-style part reference is unverifiable; the correct part is dictated by the aftermarket retrofit kit installed.): Match the replacement motor to the aftermarket power window kit installed in this truck; no factory OEM power window motor exists for the 1972 F-100.
2. 2

   Remove door panel
   Insert a door panel trim tool or flat putty knife between the door panel and metal door frame, starting at the bottom rear corner. Gently pry outward to release the retaining clips (typically 6-8 clips around the perimeter). Work your way around the panel, releasing each clip. Once all clips are released, lift the panel upward to disengage it from the window sill channel, then pull away from door. Disconnect any electrical connectors for courtesy lights or other accessories.
3. 3

   Remove moisture barrier
   Carefully peel back the plastic moisture barrier sheeting to access the window regulator and motor assembly. Avoid tearing the barrier; you can tape it back later or replace it with new sheeting. You need access to the lower portion of the door where the motor is mounted.
4. 4

   Secure the window glass
   If the window is not already in a mid-position, manually move it to approximately halfway up. Use tape (duct tape or masking tape) to secure the window glass to the door frame in the up position to prevent it from falling when the regulator is disconnected.
5. 5

   Disconnect motor electrical connector
   Locate the power window motor electrical connector inside the door. Disconnect the connector by pressing the release tab and pulling apart. Note the wire colors and orientation for reinstallation.
6. 6

   Remove motor-to-regulator connection
   Locate where the motor drive gear connects to the window regulator mechanism. This connection may be a gear mesh or a drive cable. If it is a cable-driven system, disconnect the cable from the motor drum. If it is a gear-driven system, the motor and regulator may be bolted together as an assembly. Remove the fasteners connecting the motor to the regulator. Count and note the exact number and type of fasteners on your specific installed system, as this varies by regulator/kit.
7. 7

   Remove motor mounting fasteners
   Remove the fasteners securing the motor to the door inner panel. The motor may be attached with rivets or bolts depending on how the power window system was installed. Count and note the exact number of fasteners on your motor. If riveted, drill out the rivets using a drill bit matched to the rivet size, being careful not to enlarge the holes in the door. If bolted, use appropriate socket to remove the bolts.
8. 8

   Remove old motor
   Maneuver the power window motor out through the access hole in the door inner panel. You may need to rotate or angle the motor to clear the door structure. Inspect the regulator mechanism for wear or damage while the motor is removed.
9. 9

   Install new motor
   Position the new power window motor inside the door and align it with the mounting holes in the door panel. Ensure the motor drive gear or cable drum is oriented correctly to engage with the regulator mechanism. Secure the motor to the door panel using bolts or pop rivets. If using pop rivets, install the same number of rivets that originally secured the motor, matching the removed fastener count and size. If using bolts, thread them in by hand first, then tighten snugly.
10. 10

    Connect motor to regulator
    Engage the motor drive gear with the regulator mechanism or reconnect the drive cable to the motor drum. Install and tighten the fasteners connecting the motor to the regulator mechanism, using the same number and type of fasteners you removed during disassembly. Ensure the connection is secure and there is no binding or excessive play.
11. 11

    Connect electrical and test
    Reconnect the motor electrical connector. Temporarily reconnect the negative battery cable. Test window operation using the window switch. The window should move smoothly up and down without binding or unusual noise. If window operation is correct, disconnect the battery again before proceeding.
12. 12

    Remove window support and reassemble door
    Remove the tape securing the window glass. Reposition the moisture barrier and secure it with tape or adhesive. Position the door panel over the door frame, engaging the top edge into the window sill channel first. Press firmly around the perimeter to seat all retaining clips. Reinstall all screws for armrest, door handle escutcheon, and panel perimeter. Reinstall window crank handle and press trim clip into place.

Reassembly

1. Reconnect negative battery cable after all interior components are reassembled
2. Test window operation multiple times from both up and down positions to verify smooth operation
3. Check that all door panel clips are seated and the panel is secure
4. Verify door locks and handles operate correctly after reassembly

Verification

• Operate the power window through full up and down travel multiple times to ensure smooth operation without binding or hesitation
• Listen for any unusual noises from the motor or regulator during operation
• Verify the window seals properly at the top when fully closed
• Check that the door panel is securely attached with no rattles or loose clips
• Confirm all door functions (locks, handles, courtesy lights) work properly
