thanks.. i tried the WD40 it did not help. I will try to buy a motor and regulator off ebay and change it.
Regarding the judderiing/shaking steer wheel.. I have brought a new tyre and it seems to have cured it.. will see if it occurs again and then take it to a garage. I jacked the car up on both sides and it all looked fine to me.
I have another problem which i forgot to mention, the central locking in the car 95% of the time does not work when i use the button on the drivers side door to lock all the doors. Only 5% or less of the time if I use the button will it lock all the doors on the car, most of the time it will only lock the drivers side door. The central locking works fine if i use the remote keyfob to lock the doors though. any ideas anyone?
