quick down/up

hello, drive the focus ghia tournament. with me on the driver side the quick down/up function is defective, i.e. the windows no longer drive automatically, but I have to hold the button. thus I can no longer close the window per fb. I was told that the engine is defective. I have now found an interesting article at ebay. however, the actuator comes from a three doorr. can I still use it? quick down/up has the focus on the driver side d Here’s the link: http://cgi.ebay.de/…1619QQihZ015QQcategoryZ38729QrdZ1QQcmdZViewIt’s just the engine, not the complete window lifter system.But as far as I know, only the motor contains this quick up/down technology, right? mfg markus
