Window Motor Replacement

Jeremy,

The Mondial 8 has a nice feature,, in the passenger door, rainwater drips right on the window motor.

The Motors are easy to take apart and clean.
The after-market motors have stronger windings.

IMO, you need to Check your grease in the gear unit.
use zip ties to hold the cable on the spool.

good luck,
Edwardo

Years ago I rebuilt both door window systems on the Mondial 8 that I used to own. I remember the grease in the gear drive assembly had hardened to the consistency of plastic. It took a lot of solvent to clean it all out. My motors worked fine after that, however, the car was only 14 years old at the time. The aftermarket motors sound like a perfect upgrade.

 

Must be for cooling purposes.

 

I just recently replaced both of my window motors, using a pair from ebay as well. I replaced only the motor units, and had to take apart the gearing to remove the fossilized grease...once I did that they seemed to work much better.

One thing I did notice as I reinstalled the motors - it is a pain to get the gearing and cablewinding just right. When I installed the drive cables back in per the Ferrari workshop manual then I found my windows didnt go all the way to the top. I've been playing around with the routing, getting the cable tensions correct, etc and still have not been able to get the windows to go the full travel up and down using the original routing diagram.

If anyone has any suggestions on getting this routing correct after motor replacement then it would be great!

 

What did you search on ebay; Ferrari Mondial window motors?

 

My drivers window isn't operating.

I managed to remove the panels and get access to the window motor. I'm unsure about the best way to proceed from here on. Preferably I would like to remove the motor itself from the rest of the unit. Any advice is greatly appreciated.

When I had to replace the window motor of the rear window someone sold me the appropriate part from a FIAT for just 20 EUR. Maybe it's possible to identify a used FIAT or Lancia motor again, if I'm able to seperate the motor from the whole unit.

I've been investigating the motors.

For the QV, as well as 3.2, 328, and 348 it appears that Bosch part numbers 0 130 821 069 (left) and 0 130 821 070 (right) are specified, as they are mentioned in various cross-reference threads. These part numbers refer to the complete motor assembly, not just the part that is technically the motor. I believe my motors (QV) were made by SPAL Automotive Srl in Italy. I don't know if the Bosch part is exactly equivalent.

I've looked at a lot of Fiat, Alfa and Lancia motors and haven't found a match. I've investigated many other Bosch part numbers without success.

Other cars that use the Bosch 069 and 070 include MB Gelandewagen models, as well as TVR Chimaera and Griffith (TVR use the -069 part). (See HELP PSE - WANTED - Electric Window Parts | G-Wagen Owners' Association for a discussion of the Gelandewagen application.) I haven't found other cars that use these, so this information is of little help, and let's face it, MB G-class and TVRs are not exactly abundant.

Price for the Bosch part seems to be around €200 in Europe and much less expensive in the USA.

In my research I found repeated references to the Bosch part numbers in association with a company called "Electric Life". Looking at Electric Life I see that they sell window motor kits, and Bosch motors as well. They do not provide the part numbers, but some of their window motor assemblies look remarkably similar to what we have.

I'm sorry I can't help you with the other issues regarding removal and reassembly, though there are many good threads here regarding those procedures.

It seems that hardened grease in the reduction gear is one of the primary reasons for slow motors, and the various ideas of cleaning electrical connections, installing relays and improving electrical grounds may only be a partial solution. Of course, the motors may weaken with age, especially if they're subjected to years of abuse due to other problems.

Best of luck and let us know if you make any discoveries in your research.

 

Having a Bosch part# is a big step forward, thanks a lot! The window motors are around 150 EUR over here.

 

AR! It seems that the motor itself may interchange with many Bosch units. This thread on fourtitude (Audi site) suggests that BMW and Saab, as well as some VW use it. Fourtitude.com - Power window regulator

There's also a link there for a site selling the "Electric Life" Bosch part for 75USD.

 

Last year my windows were running real slow almost stopping. I read about the low voltage at the motors so I removed my door panels and checked it, it was at 11 volts car not running and 13 volts car started. Then read about hard grease in the gears. This is the part that might not be for everyone. I took a 1/8" drill bit, put a depth stop on it to 3/16", a right angle drill and drilled a hole in the top of the gear housing with out removing any thing from the door. Sprayed penetrating oil in the hole while running the window up and down. Every time they got faster. Put some electrical putty over the whole. The speed going up went from 8 sec. to 4 sec. And are still working great.

 

Cleaning and re-lubing the motor and regulator is a good way to maintain everything in working order. Also, adding a window accelerator helps and making sure you have a good ground wire. I think the front motors are a piece of cake compared to what you have to deal with in the cabrio rear windows from a working space perspective. My rear windows failed shortly after I bought my car and hasn't worked in 2.5 years, I only drive the car top down anyways but do have custom plexi-glass I made in case it rains. Will be finding a solution using the volvo mechanism as an fchat member suggested. The original Ferrari design is a total failure IMHO, it forces a rod to loop into a figure 8 when the window glass goes down in a tube full of dried up grease. Try having that lil motor do that after 20 + years and you will see why they all go bad. Last week, I just changed my mom's E-class rear window regulator and that design was smart and easy to get in, replace, and got it working in 30 minutes. Maybe after Palooza, I'll find a permanent working solution once and for all that doesn't involve a SHOTGUN to the thing! errgh!

Rear Mondial windows stuck

My drivers side back window only works with a helping hand. And I fill lucky after ready about the problems others have. I've looked in the space were the the rear window motor is and can't even see a way to get in there!!!! LOL

 

Consider yourself lucky but I'm afraid its on its way out. But at least its moving, mine are totally dead. And yes, almost impossible to get the rear window assembly out, but I was able to do it without breaking anything. Not looking forward to taking out the other side. I hear it's every Ferrari mechanics nightmare to work on rear windows because of the spacing issue and that's why they charge you a hefty sum to work on them.

 

I think I'm going to spray some penetrating catalyst on that driver side rear window rod thing. May be it will help.

 

As to the rear window motor: I had to replace one of mine three years ago. My mechanic managed to remove and reassemble the whole unit (I think he used the access from the rear axis wheel well ... not sure about the right word in English). I replaced the broken motor.

In Post #12 is a photo of the unit:

I realize this is an old thread, but it still has a lot of good information. Rutlands has 308 Window Regulator/Motor Assemblies for $575 per pair. That's a lot more than the 2 or 3 year old prices in this thread. Rutlands says they are a new, more powerful design. Has anyone used these new ones?

 

Is it possible to just replace the cable? I have another window motor assy. and can not see any way to remove just the cable?

 

re hard grease, a ferrari mechanic once taught me a trick. you can spray solvent (i forget which one maybe wd40 I would not try lacquer thinners as that stuff eats plastic) into the emergency window wind socket and it will soften up the grease. 10 minutes instead of 10 hours.

 

How do you take the window gear out to clean?

 

It ain't easy. But here is a link to an thread I posted some years back when my mechanically adept friend helped me with my windows. There are some pics and I pretty much give the step by step he used to get it done. There is also a reference to a post on the 308 page that we used to guide us. Hope this helps.
