Electric Window Motors

[Deeman]

I appreciate I should have taken a photo while I had the door cards off today (der) , but whilst fixing the inner door pull that Julie wrecked, I notice my passenger side window motor and lifter is very different to my drivers side one (much neater and newer looking). The motor is bosch. Does anyone have any photos of such stuff?. I remember a thread a few year back about the unit being off a Renault 5 but couldn't find it. The reason for asking all this, is my driver window mech and motor are ste basically. I haven't changed the felts yet, as per Joe, but wonder what arrangements fellow S owners had in their doors? Any pointers to that old thread would be good too, but I cannot find it..... Pete

This is the thread:

I thought I needed a new motor, so did loads of research using the stamped part no etc, but it turned out to be a wring fault so didn't buy one. Others have though and it seems to be the right part - just remember you need to order the wrong side - you need an offside motor for your nearside window, and vice versa.

Thanks TVRGIT - I knew it was posted somewhere. The trouble I now have is that doesn't look anything like the arrangement in my drivers side. It does resemble my passenger side. I'm gonna need to take all the door cards off again and get into this by the looks of it. The motor on the drivers side is substantial, with a large worm screw arrangement running this it....(if that's the right terminology!)

Now you have reminded me who posted it, I went through normans posts going way back. Mine is the second one in the photos

[Deeman]

Hmm - on close inspection of that photo, you are indeed right!

Hi TVRGIT,

What wiring fault did you find?
The passenger window of my S2 goes down, but won't go up. I've looked at all the wires, but can't find anything wrong. I fiddled about and suddenly, the window went up. I lowered again the window and now it won't go up.
Have you got any idea, suggestion?

Many thanks,

Best regards;

Geoffrey

This is the motor on mine...

I have the same setup as in the final picture with the Bosch motor. Mine were recently grinding to a halt halfway up, so I have stripped them all back, cleaned them up, renewed the channel felt and they race up and down pretty quickly now. Just the other side to get sorted...

Switch?
Try swapping them over.

Mine are the same. O/S was very slow downwards, but would stop halfway up. It's OK now!
There's still a lot of fore/aft play at the top of the closed glass, about 15mm, although it still engages fully with the front channel and with the seal on the pram hoop. I get the impression the window would rise more freely with less play (i.e. rocking): what do others find?

Still to do the N/S, which doesn't move at all!

So there I was feeling all smug about the fact that having changed my passenger channel felt, the window now races up and down with ease; roll on a few days and I finish the drivers side to find it hasn't made nearly as much difference and the window still struggles in the last few inches.

So any advice as to where to go now? I'm planning on getting the multimeter out over the weekend and checking it isnt a power supply issue, but short of that is it likely to be a weak motor? Window alignment doesn't seem massively adjustable (it sits pretty straight anyway) and makes little difference to the speed the window goes up.

I know rubbish windows are a 'feature' of the S, but I'd like to think I don't have to take my hands off the wheel to heave the windows up every time!

If you are happy there is no mechanical issue causing this, it sounds like crappy wiring, either corrosion in the wiring or its connections. I suggest putting 12v straight to the motor to see if it is related to the wiring or the motor/lift mechanism. If the window lifts OK with the 12v on it, I would suggest adding a relay modification to the wiring to get a decent supply to the motor.

Whatever you do, don't spray anything on the window channel felts. It is a short-term fix that attracts more dirt and crap.

Have you cleaned all the crappy old dried up grease from here and re-lubed?

[ukflyboy]

As much as I could without taking all that apart, which granted isn't much. There didn't appear to be an easy way of getting the 'chain' out to clean it. Without the weight of the glass on it it seems to glide up and down pretty smoothly, but just runs out of grunt.

I think I will take the glass off the guide rail and just push it up by hand a few times, just to make sure that there isn't some weird friction in the system that the motor is struggling with.

My nearside motor had been drowned, and had seized.
I've cleaned it and got it running, but one of the gears in the gear train must be worn: it pauses half-way up and you can hear the teeth clicking. At the top it doesn't stall the motor but keeps on clicking.

I've tried to search on here using Google, but can't find a reference to this type of motor (shown in the pictures above). It's not like the Renault 5 ones on fleabay. Please can anybody remember what it is, or point me to a thread that identifies it?

Ebay searching the part number on the bare motor tells me it belongs to a Ferrari 328 (which is not exactly good news!). There isn't a number on the sticker on the gearbox, although it does identify it as LEFT DOOR.

I think I may have fixed it!

The slipping was not in the gearbox, but between the drive 'gear' wheel and the flexible 'rack': presumably, the rack had worn in two places.

Remedy: motor the rack 'out' as far as possible (i.e. window open), grip it with a Mole Wrench close to the gearbox, and rotate it through 90 degrees. Its fixing at the other end, in the slider, is an invisible crimp which allows it to turn. So now the gear engages with a fresh bit of rack. Simples! And now there is no slip, and the motor stalls correctly at both ends.
