    My driver's side window was stuck rolled down and I utilized a restart method (accessory mode, roll down, hold 5s, roll up, hold 5s, repeat once) which fixed it. However, the next time I started the car, a "Service Park Assist System" message came up on the dash, the airbag light came on, and my A/C isn't blowing whatsoever.

    I feel like it's got to be an electrical thing, so I've pulled and tested every fuse in the box in the trunk, and they've all tested as working. I've circled them all in the attached photo. My owner's manual doesn't have any info on the relays, so I'm hesitant to pull them even to test for fear of screwing something up.

    The car runs and is drivable, but I've been needing to drive older relatives for hospital visits, and I'm in a city that gets REAL hot in the summer, so transporting them without A/C doesn't feel like a great idea.

    Any help would be greatly appreciated, especially because this feels to me like a problem that should be solvable myself but a shop would absolutely hose me for.

    A Service Park Assist System message indicates a problem with the proximity detection system that helps to navigate tight parking situations safely. It uses a series of ultrasonic sensors embedded in the front and rear bumpers to detect objects in the vehicle’s path while parking. When it detects something close, it alerts you through a combination of audible beeps and a visual display that gets more urgent the closer the obstacle is.

    Since several components are affected, my guess is that you have a wiring harness issue, power supply fault, or module failure.
