Fast turn signal: It sounds like the front turn signal bulb is loose in the socket. When I had this on my car, I simply unscrewed the fixture, and jiggled the wires untill the blink was normal again. Remounted, and all was fine. Non responding window: Could be a loose wire on the switch, or perhaps even a failed motor. You'll need to perform a few more diagnostics to be sure. i.e. does the motor make a sound, but no movement? Failed speedometor: This is a non-electrical problem. I've never had an angle drive fail on me, so I honestly do know the exact symptoms. But, I had very simrlar problems like you're having when the dust cap on on my car failed to properly grip any longer (makes the connection between the angle drive input shaft, and the turning hub). My speedo wouldn't work, then all of the sudden it would bounce from like 0-60-and then back to 0 again. Most likely you'll need to remove the drivers side front wheel to inspect for tightness on the cap. -Robert vin 6585 "X"
