Hi Rushy, just had a similar problem with my V6, ie windows and locks all over the place. The water was entering the car due to blocked drains in the scuttle. these can be cleaned properly by removing the inner wheel arch covers to give you access, then using some old metal coathanger, etc, to clean them out. I also took the rubber flaps off as well. The control box printed circuit i cleaned first with wd40 and an earbud, then contact cleaning spray i bought from Maplins. Once dry it all worked ok. Re the window switches, they can be taken apart, slowly! and the contacts and circuit can be cleaned with more contact cleaner and earbuds. It worked for me, good luck. 2.8 v6 Ghia 97 :P
