I didn't find anything like; "left/counterclockwise for up, clockwise/right for down) in the Workshop Manual. But here are the instructions for height and lateral adjustment of the window.

 

Still a great help never the less Swiss, thanks for these! I can now actually visualise what is going on in there!!

Problem: Wind noise heard inside the cabin when driving at motorway speeds and/or on windy days.
Cause: Windows are not sitting high enough when in the fully closed position
Fix: Use window adjusters to raise the windows

Difficulty: Easy
Tools Required:

• Long 5mm Allen/Hex Key with ball end. (Mine is 160mm long, 120mm may work)[/*]
• Torch[/*]

Disclaimer 1: This post is a description of how I adjusted the windows on my car and does not constitute advice. Follow at your own risk.
Disclaimer 2: Adjusting your windows will increase the pressure on the window regulators and motors. If they are already on their way out, then this increase in pressure may mean they fail sooner than they otherwise would.

Note: There is no need to remove the door card for this process.

Step 1: Sit inside your car with the door shut and window all the way up. Press on the top of the window all the way along to see how much give there is, and how it varies from front to back.
If the problem is only affecting one window you should do this on the good side too to give you a guage for how much give is normal.

Step 2: Wind window all the way down. (IMPORTANT: if the window isn't all the way down you will waste a long time trying to find the adjuster!)

Step 3: Remove the rubber cap(s) from the bottom of the door. There are only two, both are for the window adjusters.
(If you found that your window was only loose at one end, then you may only need to adjust one end of the window and thus remove one cap.)

Step 4: Insert allen key into adjuster access hole, seat into window adjuster and turn clockwise.
Use the torch to help you locate the adjuster.
They are pretty tough to turn, and I'd suggest only doing a half turn at a time then rechecking.

Step 5: Repeat steps 1-4 as necessary until the window feels firm across the whole length front to back.
It is normal for there to be a bit more give in the centre and being frameless, you will always be able to move the glass slightly if you apply enough pressure, but during adjustment you should get a feel for what is normal and what is not.

Step 6: Take it for a test drive.

 

You might want to check the 'Window Regulator' topic in the stickies post section (page 37) for more detail on what the 'drivers' look like and the relationship of the adjusting screws.

Thanks guys!! Brilliant stuff. I have just picked up my new XL allen key and I am all set to go!!

 

It's probably a good idea to re-set your windows so you have a known starting postion before you start making any adjustments.

Thanks Swiss,

So some tinkering has revealed that the rear window clamp might have come loose. Basically if I pull up on the window I can raise it enough so that when I close the door it is in the correct position (only the rear 'half' of the window has dropped). If I then drive around for a day or so then the window drops back down again. I think I am going to have to take the door card off to have a look and make sure the clamp is tight enough.. I believe however that as they are clamping glass one has to be rather careful not to shatter anything.

thanks

 

Yes that'll most likely be the cause.

You'll find when the door card is off that the bolt and bracket that the glass is secured to will offer LOTS of adjustment of the window. There's really no need to go and start a turning those bolts under the door.

The torque spec for that glass bolt is 7NM. Of is you haven't got that sort of torque wrench then a firm turn of the normal socket ratchet half way down the shaft would do.

 

Thanks qooqiiu,

Love this forum, by far the most friendly and helpful of all the forums I have been a member of! Time to get my trim removal tools (which I purchased to fix a dodgy seat on my old BMW 1er) out for the second time ever!!

 

I have now resolved this, as suspected the rear clamp that holds the window in place was loose causing the passenger window to drop. Took all of 20 mins to take everything apart and re-fit.

As a side note, the car had the passenger regulator replaced just before I purchased it last year and boy the the garage who did it do a shocking job. Turns out they broke the speaker grill, broke 3 of the trim fastenings holding the door panel on and failed to correctly refit the door panel of inspection hatch beneath the panel. Shocking stuff!
