What Causes the Power Window Regulator of the Buick LaCrosse to Fail to Operate?
2 Answers
The failure of the power window regulator in the Buick LaCrosse to operate is caused by damage to the window lift motor components. Below is relevant information: 1. Body Dimensions: The Buick LaCrosse has a length of 5026mm, a width of 1866mm, and a height of 1459mm. 2. Example: Taking the 2021 Buick LaCrosse as an example, it belongs to the midsize car category with a wheelbase of 2905mm, a fuel tank capacity of 55 liters, and a curb weight of 1535kg. 3. Configuration: The 2021 Buick LaCrosse features a MacPherson strut front suspension and a multi-link rear suspension. It is equipped with a 1.5L turbocharged engine delivering a maximum horsepower of 169ps, a maximum power of 124kw, and a maximum torque of 250nm, paired with a 9-speed automatic transmission.
The other day, the passenger window of my old LaCrosse suddenly got stuck. I've looked into this issue. It's most likely due to a burnt-out window motor or poor switch contact, which often happens after summer rainstorms. First, check if the other windows are working normally—if none of them move, it might be a blown door fuse. Wiring degradation is common in older cars; last year, mine had a similar issue due to oxidized wiring connectors causing the passenger window to fail. Another possibility is grit in the window tracks or hardened weatherstripping jamming the glass. As a temporary fix, try tapping the door—some car owners say it works. But for a permanent solution, you'll need to remove the door panel for inspection. Last time, I had to replace the window track seals to restore smooth operation. Don't delay fixing this—imagine the hassle if it rains and you can't close the window.
