Dorman 42799 is a specific-fit windshield wiper arm engineered to replace the original front left arm on select Ford and Lincoln vehicles.

This part cross-references Ford OE numbers FL3Z17527A and JL1Z17527A for the same application.
Common Issues It Can Help Address
- Wiper arm that no longer holds proper tension against the windshield
- Uneven or incomplete windshield clearing on the driver side
- Corrosion, bending, or wear on the original arm
- Loose or damaged attachment at the wiper pivot
- Reduced wiping performance caused by a worn front left arm
Installation Notes
Verify the vehicle’s front left application before installation and compare the original arm’s attachment style, length, and head angle to the replacement. This part does not include adapters or an instruction manual. Confirm the hook-style blade connection and flange nut mounting point match the vehicle before final assembly.
