My Mk3 Golf O/S electric window has stopped working, I spoke to Euro car parts and they said, "before buying a new motor check to see if the regulator has burnt out". Problem is I dont know how to do this. Basically if I push the switch the revs drop slightly and I hear a click, but nothing happens with the window. Help please.... New regulator from Euro Car Parts: 50 + VAT New motor with regulator from Euro Car Parts: 145 + VAT
