Yep, but not on a 2000. I just did it on my '93 Bravada. If it's the same sort of thing, there's excess grease inside the motor that heats up and drips down onto a bi-metal 'breaker', tripping it. You can't move the window again until it's cool.

I got my window motors on eBay - the place had a 2-for special (both fronts were bad). And, even with shipping, the 2 cost less than one in the local store.

I found step-by-step pictures online, specific to 1st gens, and got it done reasonably quickly. We had the help of an pneumatic die grinder to grind off the heads of the rivets, though. The rivets that hold the assembly to the door are rather beefy. The rivets that hold the motor to the regulator/track aren't and could have been drilled out with a cordless drill.

The replacement motors came with bolts & nuts to attach the motor to the regulator/track, but I had to find bolts to attach the assembly to the door.

It's not fun, but it's not terrible.
