Solution

1. Preparation

Gather tools and parts: OBD-II scanner, multimeter, screwdriver set, replacement fuse (if needed).
Ensure the vehicle is parked on a level surface with the ignition off.

2. Inspect and Test the Power Mirror Switch

Remove the door panel using a screwdriver to access the switch.
Disconnect the power mirror switch connector.
Use a multimeter to test for continuity in the switch. If there is no continuity, replace the switch.
Reconnect the switch.

3. Check the Wiring and Connectors

Inspect the wiring harness leading to the power mirrors for any visible damage or wear.
Ensure all connectors are securely attached and free of corrosion.
Repair any damaged wiring or replace connectors as necessary.

4. Test the Power Mirror Motor

Disconnect the mirror from the wiring harness.
Using jumper wires, connect the mirror motor directly to the battery to see if it operates.
If the motor does not work, replace the mirror assembly.

5. Check and Replace the Fuse

Locate the fuse box for the F-150.
Identify the fuse related to the power mirrors and check if it is blown.
Replace the fuse with one of the same amperage if necessary.
