Hi All
I have managed to get the window fixed a new motor/regulator was required, if anyone should have to get this done on their westcoast you will have to have the bodywork trimmed by the window to allow the rear quarter window to come out as it comes out from the top.
A massive thank you to Wayne from Beemabuild who not only trimmed and made it good afterwards but also found a garage that would carry out the window motor replacement as it seems that some garages are put off wanting to do the work because it has the bodykit on it (we tried 2 merc garages first who would not do it).
Anyway it is now all working as it should and you can not tell that the rear wing had been trimmed and then made good again although it took about 3-4 weeks what with the other garages having the car then saying that they could/would not do it, i hold back from naming them but if you have to have this done then make sure the garage will and can do it.
