I have a Honda Accord 2005 with a funny problem... The power window don't work except for the window of the driver... when I click the switch from the driver side, the other window click but don't go down... what can be rong?

Sounds like the window gear is slipping at the motor. The gear on the window is easy enough to replace, but with my experience on these, the motor gear is non-replaceable and the motor will have to be replaced. This type of motor has brushes and the brushes get worn and dirty. When that happens, the motor gets weak and cannot provide the torque to move the heavy glass. This can also cause the clicking, but I would check the gear set first. It is not time or cost effective to replace the brushes.
