HELP PSE - WANTED - Electric Window Parts
My third G over 20 years is a SWB 2-door G463 300 GE 1993 and so has electric windows. The left/passenger window has stopped working and my husband has managed to determine that 12v power is available from its switch to the motor input - then nothing! Can anyone provide or point me to an affordable replacement - I gather this means replacing the regulator mechanism as well as a new motor, even though the regulator seems fine. Xtn
Hi, I had the same problem a couple of years ago. I had to replace the motor only, not the rest of the mechanism. The motor is available from your local Bosch auto electrical garage. I replaced the drivers side window motor. The Bosch part No. was 0130821070, at a cost of £180, I am not sure if the passenger side and drivers side motors are the same. Maybe some else on the forum can comment?
Changing the motor out is a DIY job, but does take some time and is "a bit fiddly". From your post I assume the door card off already and the voltage arriving at the motor has been tested OK.
I disconnected the window from the regulator and wedged in place, then removed the whole motor / regulator assembly from the door, changed the motor and then re-installed.
One thing to note - is that it matters which way round you plug in the electrical supply to the motor, otherwise the window will go down when asked to go up etc. Important for when you test the new motor once attached to the regulator, prior to re-installing in the door. So you do not run the window holding plate off the top of the regulator mechanism - I did and it took me some time to resolve, once I had stopped cursing!

Alex

Hello xtn,
I think you will find the motors to be handed due to the gear mechanisum. £180.00 sounds a lot for a motor alone. Check with your dealer the following part number or better still ask them to look up the regulator for your chassis number and compare that with the price of the motor.
I have looked up a W463 - 300GD part number; only coming back to your thread to find out that you have a 300GE. I do not expect there to be any difference in part number but better to be safe than sorry.
For a chassis number W463 - 300GD, Chassis 463.327, Left hand side window regulator, part number is A460 720 07 46. The motor alone is not available from the dealers.
I would ask you to make a separate "earthing" for the motor, by using a bridging wire (piece of wire) and using that to earth the motor from its earth connection at the socket and another point on the body and see if that completes your circuit for the motor to work; failing that, instead of using the earth at the socket try the body of the motor to do the same. Water ingress in the motor can cause failures, check to see if anything is obvious or apparent, striping the motor.
If you could furnish me with the motor number and the gear count on the winding mechanisum and, or any printed information from the motor, it may assist me in finding you a replacement motor, hopefully at sensible prices.
If you find your motor works with a seperate "earthing", then look for a broken eath wire at the door pivot.
I know there are a number of discussions threads already in the forums about widow motors. Unfortunately, I can not get the search function to work on my work computer. But you should be able to find more information - with patience.
As an aside - looking online - the price for a regulator and motor on the American site Fourbyfourclub.com is $849. So, who knows what a Merc UK dealer would charge!

The motors are definetly handed. I purchased a new one from a Bosch dealer for over £150 5y ago. I would pull the regulator out of the door and check it before buying anything. Unbolt teh motor from the regulator and see if it works independently.
I did a write up about repairing these in the club magazine a few years ago. Motors are very strong
Guys - many thanks for all of this. Husband has got it working for now with judicious quantities of WD40 and oil - but is a bit concerned that it labours on the way up and motor feels hot - also, that it worked better on his bench - doesn't want to put the trim back until we're sure we don't need a new motor as it's been fiddly and time consuming.....!! Xtn
Hi
it will need lifting help in the "closing" mode in order to clean the spiral drive guide which is obviously very rusty and causing increased friction ...you may not be able to remedy the fault using the existing spiral drive without removing the assembly and giving it a thorough de rust and grease... even then you may have to get a new one ..sounds like the motor is ok just labouring against the resistance from the corrosion in the spiral drive guide .....
Impoved, but still not quite right--any further ideas?
We have removed whole assembly (more than once!) and there is no rust or impediment to the spiral drive mechanism--which nevertheless has been cleaned and massively lubricated.
The motor was separated from rest of mechanism and got hot, stopped with a click, but after 5-10 seconds would restart after another click (?safety cut-out).
Motor was then taken "apart" by undoing two bolts so that worm-spindle could be withdrawn from plastic cog. No signs of corrosion, fires, or interfering shards of plastic etc. It was reassembled after greasing and then it ran without stopping or getting so hot.
It was therefore reattached to rest of mechanism and whole thing reinstalled.
It was initially nursed/helped with uplift mode and now runs without cutting out--but irritatingly and unacceptably slowly, despite fiddling with/optimising alignment and bolt positioning.
So--are there other tricks or diagnostics to consider? or do we just have a tired motor? In which case, is a more sophisticated refurbishment available? Or does anyone have a motor (Bosch 0130821069) or complete mechanism at something more acceptable than M-B prices?
Yrs, in thanks and hope.
Have you tried operating the window outside of the window channel? Compare performance inside and outside the channel. If it operates fine outside, turn your attention to the channels. Try and hand operate the window glass up and down; does it freely travel, if not, clean the channel with spraying aerosol clutch and brake cleaner.
After that has dried off, apply some graphite grease along the channels or spray the channels with channel lubricants available from Wurth or see if your local motor factor has a substitute spray. The worse case scenario will be renewing the channels.
The Bosch motor part number you have supplied is valid and a replacement motor is available from Germany by next day delivery (ordered before Noon) at £211.87 plus VAT. Your local Bosch dealer can order this for you. The Mercedes-Benz price for the regulator is £413 plus VAT.
I wonder if you have tried G-Wagen International Ltd, to me it would be the first port of call for secondhand parts.
Try James Lafferty at:

From the Bosch dealer it might be worth asking them of an application list for the motor number you quoted. If they are able to provide this information and the same motor is used in another M/Benz model, it could be easier to source a reclaimed part.
In the mean time I have feelers sent out to some German sources, I am waiting on replies from them.
Cheers
Hi
Rakesh is right as usual with the MB parts side of things
MB number for Regulator and Motor is A460 720 07 46 Superceeds to A4637200846
£413.00 + VAT MB Germany have stock
I could get you 20% of the retail + VAT and post to you.
Alternatives are Ridgeway MB in Southampton have 2 in stock and may do you a deal if you call them 0844 8807979.
It also looks like the Bosch motors 0 130 821 069 LEFT and 0 130 821 070 RIGHT are used on some other cars of the era.
Long shot... Ferrari 328, 348, F355, MONDIAL QV, AND MONDIAL T!!!! + others
New ones on Ebay in the US for £135 + shipping 6 in stock Item no 150603657745
Better shot in the UK maybe Audi 80 and Quattro but you need to confirm numbers on the motors..
.i think you may need a right one from an Audi for a left G wagon.
Available on Ebay for £25 ish or local breakers
62302100 and 62302200 are possible interchangable numbers from Ferrari.
Hope this helps

Thank you so much everyone - we think we have it sorted. Message from husband is that he's not sure which part(s) of taking it all to bits, cleaning, lubricating and putting it back together again has done the trick but it is now working as well as the driver's side - so steady as we go!!

Nice to hear your hard work has paid off. But in case you are still in the market for a new regulator, I have sourced a supplier in Germany who supply one at €195.00 plus p&p.
Cheers,
Many thanks Rakesh - this is much more reasonable than MB but fingers crossed we won't need it.... Xtn

Many thanks for this Alex - yes the door is in bits and 12v is getting to the motor.
It's good to know that the whole lot may not need to be replaced. Does anyone know whether both passenger and drivers side motors are the same - would think so - can see why the regulators would be different though...
Many thanks. Xtn
