Problem for Mitsubishi 2002 Galant

FRONT LEFT WINDOW DOES NOT OPERATE




By Veerkar on Feb 02, 2009

" "
Front left window glass moves downs only about an inch and then stops. Moves up smoothly. No bind between the glass and channels. When the glass stops after going down for about an inch motor also seems to be not trying. Initially motor seemed to try to pull down but glass wont go beyond an inch or so as if there was a bind. But now even motor stops pulling down after the glass goes down an inch.
Suspect regulator. Want brief instruction to remove regulator and install a new one. Have removed the door panel, It appears that the accesst to regulator is poor and not sure if the regulator would come out through the openings provided on inside metal sheet of the door.

- Thanks a lot. I think that should help. I will give a feedback as soon as I give it a shot. Today weather here is really bad - can't venture out to work on the car. I imagined that there would be two limit switches to sense the two extreme positions of the glass to send signal to the motor to stop. But I understand that there are no switches. Circuit itself registers the extremes by sensing the overload on the motor when glass reaches its end and then "remembers" these points so that next time, drive to motor is stopped when the glass reaches the extreme point. This perhaps makes sense and explains why motor now does not drive after pulling down the glass for an inch - it must have falsely registered this as the end point by sensing overload on the motor. Do I have to do to "reset" this falsely registered end position for the glass once I replace/rework the regulator? Also for my knowledge could you tell me how the circuit remembers the end point?

i would say it is the regulator (so have a new one/or good replacement), and it will come out of the openings. once you have the bolts removed for the regulator the window should come down to a place you can remove the bolts that attach it to the regulator. After the window is unbolted side it back up and tape it up and out of the way. you will need to likly use the old motor on the new part but it just bolts to the regulator. Once you have the moter on install it in the door. Good luck

My window was experiencing the same problem, although it never worked poorly, it only quit working downwards, but went up fine. The trouble was in the switch. Disassembled the switch, re-set the pegs and springs, re-assembled and now everything works fine. I assume one of the pegs simply sprung loose, and would contact the plate when "up"position, but was too far out of reach to contact for "down". If the regulator wasn't the problem, this is much easier to check. Make sure if you do disassemble the switch to keep it upside down when you do it, so as not to loose the pegs and springs within. Hope you found a solution.
