Car Forum / Honda Cars / August 2004power window problem
My wife's 2000 Civic has powered windows. When the windows are mover past the half way down point the motor struggles to move the window up. I unhooked the window and the motor seems to move fine, but with eh window attached it really struggles. I have oiled the slide and cable that is used to move the window. Has anyone had this problem and what does it take to fix it. George Taylor sanddollar3@att.net > My wife's 2000 Civic has powered windows.

It sounds as if there is something binding the drive mechanism that with the additional weight of the window it has a hard time handling (a gear or coupling or the track itself). It could also be the motor. Most small DC drive motors are of the brushed type (at least the lower cost ones). If the brushes get worn (or are defective) or if the interior of it gets a lot of dust from the brushes or other sources it can weaken the field that is used to drive the motor windings. > My wife's 2000 Civic has powered windows.

I [quoted text clipped - 4 lines] > George Taylor > sanddollar3@att.net I agree with the intelligent poster that said the window might be binding on something. I just wanted to add that this could also mean that the motor is about ready to stop working. In many cases--with electric motors--they run poorly prior to the point where they stop working. In many cases, it's cheaper to replace the motor than it is to pay someone to repair the motor. If you have to replace the motor, your best option is to go to a auto junk yard and buy it. If you can install it yourself, you will save lots of money. Don't bother buying a replacement motor until you determine whether or not the window now in the door is binding. If it is binding, a different motor will not solve the problem.  SignatureNEWSGROUP SUBSCRIBERS MOTTO We respect those subscribers that ask for advice or provide advice.

If it is a brushed motor, and you can get the motor manufacturer and model number, replacement brushes are only a few dollars (usually <$10, even for some of the 40-50HP DC drives I've worked with) and can be ordered from industrial companies like Dodge Newark. My own experience w/dragging PW motors (bogging down under load) was that the armature contacts were loaded up with grease and hence the brushes couldn't achieve good contact. Dunno what you could use today, but 10 years ago a couple good shots of Blue Shower (1.1.1 TriChlorethane) would flush out the goo. WD40 as a cleaning/flushing agent (not as a lubricant) might work. >> In article >> <OuPOc.360441$Gx4.292349@bgtnsc04-news.ops.worldnet.att.net>, "george [quoted text clipped - 25 lines] >some of the 40-50HP DC drives I've worked with) and can be ordered from >industrial companies like Dodge Newark.
