Thanks very much. And WD40 on the window switch - just squirt from on top, or do I need to take it apart?

forgive my ignorance - do you mean taking off the internal door cover, or just opening the windows a bit and squirting down the edges of the windows?
And silicone - do you recommend anything particular? Google came up with http://www.cleaningsupplies4u.com/product/ptfe-silicone-grease-480ml/?gclid ...

Hi dext924 - where precisely did you squirt the WD40? Into the driver's switch? My windows are somewhat intermittent, though normally waiting a minute seems to work. But I'm nervous it is the motors as both windows sometimes look as if they are really struggling to get up.
Cheers!
