power window travel stop

PostPost by: rdssdi » Mon Jan 07, 2008 2:47 am

This subject was discussed earlier. It was the consensus that the pair of screws (2 BA thread) that secured the armrests acted as the side power window stop. If the window is allowed to travel completely downward it will skip off the gear and not return without manual coaxing.

I threaded in the armrest screws and ran down the window. It nearly tore out the threaded metal insert in the fiberglass. It certainly does not seem a satisfactory travel stop.

Can anyone supply photos of the interior of their door detailing the window mechanism and track? Is there a rubber bump stop at the regulator arm or at the nylon track guide?

There has to be a firmer better suited travel stop than the arm rest screws.

Thanks

I was told that the Europa windows uses a bolt as a limit stop. Apparently it contacts the actuator arm.

Can anyone confirm this for a +2

Hi Bob,

I've just about finished re-fitting the windows on an early +2 I'm working on and have had a similar problem. The passenger side works fine and stops just below the window seal. The drivers side though, drops off the gear about 1/2 an inch above the seal. Due to work, I haven't had a chance to figure out why. To my mind, the only solid way of stopping the window it to have a stop in the frame runner. If the stop was on the bracket that holds the actuating arm - a bolt etc - the the torque acting on the stop would be under too much strain.

Just an idea, but maybe the front bottom frame fixing bolt needs to be long to prject through into the frame?

It is interesting that one of your side windows will retract fully. At that position will it return without assistance?

I wonder if the windows are supposed to fully retract i.e. top of glass at or slightly below the rubber.

Can several people reply as to the normal window travel for their +2?

I will get a good look today at the shop. I printed a photo that I took before disassembly of the door. I will compare to see if I incorrectly fit the mechanism.

Thanks

Hi Bob,

The window that retracts fully does wind up and down once it has hit the bottom (passenger side). The other side won't wind up from the bottom without being lifted slightly back onto the gear.

I remember from my Fathers +2 years ago, that both windows retracted to just below the rubber seal.

The car I am working on is being re-built from various boxes from when it was stripped 10 years ago. I'm sure some bits have been lost / mixed up with other +2s at the company which originally started the re-build.

I think I may somehow have a R/H motor and mounting bracket, but with a L/H operating lever! Looking down the centre line of the lever, the operating gear is offset i.e. there are more teeth to one side than the other. This is just a theory at the moment though....

When taking the mechanism appart, beware of the coiled spring!

Both windows on my +2S stop just at the rubber strip. I haven't had them apart for 25 years so I don't recall what forms the bottom stop.

My windows and frames are rebuilt, re-chromed and assembled.

The LH marked motor goes on the right side and vice versa. At least that is the way my car was before I disassembled it.

I wonder if I assembled something wrong and the window runs out of gear at the bottom. I did not remove the arm from the plate and the motor gear is certainly not "registered" to a position on the other gear.

I will look at the car this afternoon.

Driver's side window stops slightly below rubber seal, passenger window stops around 1 inch proud, with a clonk! I always had a feeling that it was stopping on one of the armrest bolts, but have never really followed it up. Stopping slightly below the rubber seal seems more natural, looks better and helps when reaching out of the window (toll booths, parking barriers etc).

It appears that windows may halt their downward progress at position between an inch or so above the rubber seal to slightly below said seal.

If anyone has a functional window with the door panel removed, kindly look and see what and where contact is made to stop the window. A mirror may be useful.

Thanks

Bob, have just rolled my early car(chassis no. less than 300) and can report that both windows stop just below the level of the rubber seal. Removal of the door trim shows that the window stops moving when the plate attached to the glass frame contacts the stop moulded into the inner face of the door . Have taken a few photos that should make things clear.

I always thought that moulding in the door was for assembly at the factory to help lifting the door!

As one of my windows drops off the gear, I'm guessing the door glass bracket doesn't have the small plate sticking down at the rear edge - something else to check at the weekend...

Would it not be possible to reposition the motor&operating arm assembly so that the glass reaches the end stop before the gear drives off the motor??

Your findings are what I originally assumed. Although it appears that on my car that molded stop is too far from the window frame.

I will take a closer look as it is the most logical. I wonder if it is possible to reverse window sides and have the "bracket" now no where near contacting the stop.

A closer look will occupy tomorrow morning. I will take photos to compare with yours.

Thanks
