It’s the motor and mechanism assembly the makes a car window go up and down

Is it as much fun as I’m imagining?

That’s awesome! My parents weren’t very supportive when I wanted to do my own maintenance in high school. My first breakdown was a bad throw-out-bearing that grenaded and took out the clutch. With no experience, I was determined to do the job myself. I towed the car back to our house, jacked it up (with the one in the trunk), put it on cinder blocks (didn’t have jack stands)…and immediately gave up at the first rusty exhaust bolt.

I later did a bunch of car work in and after college while getting my mechanical engineering degree. This skill was super useful so that I could own older cars that were cheaper to buy but had some issues. I could fix them and save money.

There’s something meditative about being under a car. The whole world disappears and your only problem is this one stupid fastener. It’s immensely satisfying to finish a job and the car just works again.

Soon your kid will be noticing how a disturbing amount of parked cars are missing a lug nut. He’ll be the one to inform his friend that weird noise in their car is easily fixed but could cause big problems if not addressed. The lube tech will no longer be able to upsell him on some bullshit that his car doesn’t need.

Btw how old is he?

What car?
