Lift the wiper arm from the windshield, then press and hold the wiper lock pin (or button) to release it. Next, slide the wiper along the wiper arm to remove it.

As an experienced mechanic who's removed hundreds of Buick Excelle wiper blades, I know the devil's in the details. First, turn off the engine and immediately push the wiper stalk downward to activate maintenance mode - this lifts the wipers upright. Lift the wiper arm about 60 degrees until you hear a 'click' locking it in place. See that square plastic clip at the joint? Press hard on the raised center of the clip with your thumb while pulling the wiper head outward with your other hand to remove the old blade. Always lay a thick towel on the windshield - if the wiper arm slips, it could shatter the glass. Installing the new blade is simpler: insert the U-hook into the slot until you hear a 'snap' indicating it's locked. DIY wiper replacement saves big bucks - OEM blades cost over 200 yuan, while quality aftermarket ones go for just 80.

Last time I changed the wiper blades, I spent half an hour figuring it out myself, and later discovered the trick lies in the clip position. Don't rush to start after turning off the engine—first switch the wipers to maintenance mode: within 10 seconds after starting and then turning off the power, press the wiper control lever all the way down and hold for 3 seconds, and the wipers will automatically stand up and lock in place. Then, pinch the wiper blade near the connector, locate the U-shaped metal hook at the bottom. The key is to use your fingernail to press the plastic latch inside the hook while pushing the entire wiper blade toward the front of the car to unlock it. For post-2016 Excelle models, note that the connector has changed to a direct plug-in type, with the clip moved to the side. Be careful not to get the sizes wrong—26 inches for the driver side and 18 inches for the passenger side—installing them backwards will cause interference.

Just replaced the wipers on my Buick Excelle, and it was a bit challenging for a girl to operate. Found out a special technique is needed: within 30 seconds after turning off the engine, flick the wiper stalk to the single wipe position, and the wipers will stop in the vertical position. Here's the key! When removing, use your knee to brace the wiper arm to prevent it from snapping back, press the spring tab at the bottom of the metal hook with your left hand, and twist the wiper head counterclockwise about 15 degrees with your right hand. Note that the old rubber blade might be sticky—clean the bracket with an alcohol wipe when peeling it off. Don’t skimp on frameless wipers; the cheap ones I bought before started skipping in just two months. Remember to measure the original size from the end of the rubber blade when checking the dimensions.
