Sorry to resurrect an old thread but I've just had this happen today.
No wobbles, no warning - the glass on the drivers side just decided it quite liked a particular spot on the M5 and exited at a great rate of knots giving the door a couple of 'kisses' on the way past. Fortunately there was nothing too close behind and luckily no damage other than the lost glass.
Because it's the drivers side though, it made the journey home back up the motorway a bit of a nightmare so I headed straight off to the dealership and picked up a replacement which is now fitted.
I decided it would be a good idea to check the passenger side in case that was loose too and it seems pretty mobile although still not showing any visible wobble when driving. I'm going to attach it more firmly now though before it's too late.
My question is directed at those who have used sticky pads to re-attach their glass. Does the air gap created by the thickness of the pads affect the performance of the heating element drastically?
Does anyone have a brand name for a glue that works well to avoid the air gap?
Any help and advice much appreciated.
Thanks in advance.
