How to spray windshield washer fluid in the GL8?
2 Answers
Buick GL8's windshield wiper and washer control switch is integrated into the combination switch located behind the right side of the steering wheel. The operation modes of the wiper and washer are controlled by manipulating this combination switch. Please note: Do not operate the windshield wiper when the windshield is dry or covered with snow/ice, as this may damage the wiper blades, wiper motor, and glass. Here are some additional details: 1. Windshield washer fluid is commonly known as "glass water" in automotive terms. It is a consumable product in vehicle usage. High-quality windshield washer fluid mainly consists of water, alcohol, ethylene glycol, corrosion inhibitors, and various surfactants. 2. When the transparency of the front windshield decreases, spraying glass water can provide you with a clear and bright view. Especially during nighttime driving, dust on the glass can scatter light. In such cases, spraying glass water helps maintain the front windshield in optimal transparency.
Using the windshield washer fluid in my GL8 is incredibly simple. Having driven this car for almost half a year, I find the operation very intuitive. First, locate the control stalk on the right side of the steering wheel—the same one you use for turn signals. When parked, gently pull it toward yourself, and it will spray fluid onto the windshield while the wipers automatically swipe a few times to clear debris. I find this design quite user-friendly, especially during rainy drives when visibility gets blurry—just a quick pull and the view clears up. Remember, the washer fluid reservoir is under the hood on the driver’s side, marked by a blue cap that twists open for refilling with dedicated washer fluid. I usually check the fluid level monthly to prevent it from running dry. In summer, I use the standard type, but in winter, antifreeze fluid is a must to avoid nozzle freezing—last time I skipped it, the ice buildup caused a hassle. If the spray nozzles are misaligned, a fine needle can gently adjust their angle. This minor maintenance ensures driving safety—on highways, one spray clears away bug splatter and dirt instantly.
