I just got a vRS and managed to knock money off because the electric windows weren't working.
I checked 3 fuses behind the panel on the drivers side of the dash, 46, 58 and 68 (If i remember correctly) and all seemed okay.
I swapped 46 and 58 for new fuses and they still didn't work. I took out 68 and gave the blades a bit of a scrape with my nail and put it back in and they both started working!
From searching here and other forums people are saying that if your car is a bit damp inside then the fuses can become corroded and this affects the contact and stops them working.
Maybe it was a coincidence i did this and they started working but might be worth a try
