Window Motor Overhaul

#1

Post by Mike.Lawre » Sat Oct 20, 2012 4:44 pm

If your window motor gradually stops working it may not be beyond recovery. This is worth a try before you invest in a new one. Apologies for the poor pictures ( my camera doesn't like close-ups ) :character-oldtimer:

Remove the motor ( it pays to put a cable tie round the cassette before removing to avoid the cable springing out ! If it does it's a right pig to rewind)

Undo the four screws and remove the case


Remove the shaft ( pulls out)


Check that the brushes are free to move up and down and are clean ( you can stretch the springs slightly if necessary)


Clean the grooves in the commutator with a sharp blade and clean the copper strips with emery paper


Put it back together ( being careful with the brushes) AND HOPE!

and done me out of a few being as I have both motors sat waiting to be sold lol :laughing-rollingyellow:
(joking, tbh they're the sort of thing I'll be happy to hang on to as spares for myself! :handgestures-thumbupleft: )

good write up, and in my opinion its better to try and fix first than just default to replace

My drivers window has failed after moving it Down then up to clear rain water.

Which part do I cable tie? Is it any of the parts in your pictures?

Thanks.

If you look in the top two pics you'll see a white plastic cog. That cog joins the motor to the cable cassette which is like a tin can in two parts. This is the bit you need to wrap cable ties round before separating it from the motor.

Cheers, thanks for coming back to me. I've read a lot about the springs being a pain to wind back in, but didnt know where yet were!

Thank you

Just a note, I managed to get just the motor part out by undoing the 4 screws from inside the door panel :)

Hi mark. You didn't take the window out etc like on the new tib diy's did you?

I haven't even taken the door card off yet. It's probably all very obvious when you're looking at what your dealing with!

Thanks

No, I took the black panel off near the motor and unscrewed the bolts holding the motor to the door, then it gives you a bit of movement to get access to the 4 screws, you need to do it without lookin really, I had one hand going into the door holding the motor, and my other hand with the screwdriver through the access panel. Your probably best with 2 people becaudse once the motor is out the window can move up and down, then just push really hard and wiggle it to get it back in :)

Having followed all the advise on here I felt confident enough to change my window motor today. Bought a new one from the dude in Korea. Swapped it over and even managed to avoid the old one flying apart (thanks to this forum). However...it goes down ok and comes up ok apart from the last 4 inches or so where it struggles.....any ideas anyone? thanks - H :confusion-shrug:

LUbe up the joints, give it a bit of help and get it going up and down, it might just be a bit sticky to start with.

Obviously if it really won't go, don't force it, but a little encouragement might help

Silicone spray in the runners and on the mechanism should do the trick

Has anyone replaced the brushes ?? I need some if anyone knows where to get them.
Also if you go to the trouble of pulling motors off to clean you may as well fit new brushes ,,, that is if I can get some. My motor is off and yes the window falls down after a while :icon-lol:

Just a quick one reference new brushes. I had my drivers side apart today and the brushes had gone which was why the window wouldn't work. I didn't have any that fit so as a temporary repair I removed the ones in there and turned them 90 degrees and put them back in the sliders. Maybe a temporary fix but it has made the window work again!! Didi you have any luck sourcing replacement ones as I would like to have some ready for when it packs up again. Cheers.

Try these people, I used to get brushes for my model car & boat motors along with other stuff. You can buy blanks as well and make your own up. Nowt you can't get to fit with a bit of careful filing
