| My 94 740IL's driver side power window will not go up or down. All the other windows work as they should. The motor is fine because I can put 12 volts directly to the motor and make it go up or down. The switch is fine because I put in another switch and got the same results. It also makes a click sound under the rear seat when I press the switch in either direction which leads me to believe the switch is good. I put a multimeter on the plug at the motor and it is getting 9 volts in either directions. Has anyone else had this problem? I'm guessing there must be some sort of voltage regulator problem? Any suggestions are appreciated. |
