Not a hijack at all - the purpose of this thread is troubleshooting power window problems.

Slow motor can be lots of things:
  • Brushes/mechanical wear like Vicegrip says
  • Mechanic issues with the window mechanism itself - rust, grime, damage, etc.
  • Corrosion inside the switches - if the switch contact ends are corroded, they will offer some electrical resistance in series with the motor. Resistance x current = voltage drop (it's the law). To test this, pull the appropriate window switch out and jump across the pins to effectively remove the switch from the circuit. What pins to jumper where are explained in the first post. If the window goes up and down just fine, replace the switch. This would be the first thing I tested.
