How do you replace Mazda 626 wiper arm?

To replace the wiper arm on a Mazda 626, first lift the wiper arm away from the windshield until it is at a 90-degree angle. Locate the small tab or clip on the underside of the wiper arm where it attaches to the wiper motor shaft, press it to release the arm. Carefully pull the wiper arm off the shaft, then align the new wiper arm with the shaft and push it down until it clicks into place. Finally, lower the wiper arm back onto the windshield and ensure it is secure.
