Screeching windows - grafen
It's probably been asked before, but how can I stop my front windows screeching against their seals when going down? The motors seem to be having a real hard time moving them in either direction. I've tried silicone spray but to no avail...

Thanks in anticipation.

Do the job properly! ;-)

Take the door trim panels and waterproof membranes out, check and adjust runner alignment if required, then lightly lubricate.

I missed a bit (in bold);

Take the door trim panels and waterproof membranes out, clean both glass and runners, check and adjust runner alignment if required, then lightly lubricate.

In the case of the car I did this too - successfully - it was easier to remove the window glass to do a pukka job than fiddle around trying to clean the runners with it in situ.

I squirt duck oil down the rubbers and get the window to go up and down a few times.
Never had to take the door card off unless water has penetrated the mechanisms and then the cables will quickly break anyway.
Remember if you live or work near a dusty environ then windows stick a lot quicker.

I forgot to say, the problem only exists when it is hot n dry - such as now. I'll try the duck oil first before I have to resort to major surgery!

Thank for the replies so far.

If it's the rubbers screeching when they are dry try giving them a light coat of talcum powder. Alot less messy than oil and doesn't attack the rubber like some oils will. It also stops door rubbers sticking in cold weather.

On a similar note:

The driver's window motor on my Z28 is playing up at the moment. It's a well known problem where the built-in overcurrent sensor becomes more and more sensitive. It gets to the point where the window will raise a couple of inches then need a minute or two to rest before it will move another couple of inches.

A few weeks ago I called GM Europe to order a replacement motor. I was told that they are only supplied complete with the regulator arms and the cost is approx £400 per door. GM USA supply the motors on their own so last week I ordered two for $39 each plus $60 air freight. Total cost £70 plus any import duty I end up paying.
The recent Rip-Off Britain report was damn right. If you don't look around you can get taken for a ride.
