Howell, thanks for the offer of help. The weird thing is that when the "bang" happened, I was going ~90 MPH, and the window did not come down then, and is still fully intact and not cracked/broken as much as I can see of it. I reached my destination, and when I tried to put the window down, it came down with a lot of noise, so I let go of the switch, paused, and tried to put it back up, but it wouldn't. At that point, the window was held up with friction, I guess. When I parked for the night, I pulled the window up all the way up, but it the morning, it had come down by half on its own. I drove back 470 miles with wind noise because it never stayed flush with the top. Yes, now I hear noise when I operate the switch, but the window does not move. I understand that even if the motor is working, it is sometimes integrated with the crank mechanism and so the whole thing may have to be replaced. I'd do the job myself, but I'm a bit of a clutz, and taking off the door panel and putting it back on scares me more than replacing the power window mechanism itself!
Mercutio, it always amazes me how some vehicles run for so long. Statistically, maybe that one car ended up with perfect mechanicals at the factory, and if properly taken care of, is more durable than vehicles not so lucky to get a perfect fit. Prior to this car, I had a Honda Civic for 8 years that I put 175k miles on. While mechanically it was falling apart fast, its body was ok. This Camry now is the opposite; it still beats the pants off my wife's 1999 Civic with 13k miles on it. But I was shocked to find rust spots on the roof above the passenger area. I thought contemporary cars (especially the non-cheapo ones) had better metal pre-treatment and paint. The car has been garaged all its life, except for the year I was away when it sat in a vacant lot with a good quality car cover on it.
Incidentally, when I got back, I had the car towed to the nearest dealer (the battery was d-e-a-d, and I was sure the engine oil had turned back into crude). On the way, the tow truck took the freeway at 65 MPH. Later, the dealership called to tell me "Honest, when we popped the good open, a hare jumped out and ran off. He's chewed up most of the hoses in the engine compartment". The poor guy made his home in the engine compartment, and got the ride of his life! He also got separated from his family. Dumb me, I didn't think to pop the hood open and make noises to scare off anything that may have been inside. But you'd think with people standing around talking, a noisy diesel-engine tow truck and all that, he would have taken off on his own.
