Left rear power window stopped working, in the down position, in my cutlass ciera when I was two states away from home. And it just started raining. Took the door panel apart, put some nails in the electrical contacts, and used jumper cables (carefully!) to raise the window to the closed position.
When I got it home I read the wiring diagram, did some voltmeter tests, and decided it would be lazier to ground some wire right at the switch, disabling the driver's door controls but allowing local use.
Honorable mention goes to my dodge neon that blew a head gasket in Epsom, NH. I filled a McDonalds cup with warm sink water three times to refill its radiator, and I took one more cupful of water "to go". Temp stayed normal until I was 7 miles from home when it started creeping up, but I made it. Fixed the HG only to have the thing rot out from under me a year later.
