I know this thread is a little old, but I just wanted to say how much I LOVE THIS FREAKIN' SITE!!!
My window defroster stopped working about a week ago and I really had no idea how to fix it. I was worried that I was going to have to take the dash board apart, and maybe take the heater unit out from behind the dash. UGH!! I jumped on the site real quick to see if anyone else had had the same problem before, and during my search I ran across this thread. My issue wasn't the same as Mark's, but his picture and description of what was going on got me under the dash where I saw a little metal rod, a little higher up than his picture, that was disconnected and hanging free. Opened the shop manual to find out what the rod should have been connected to, found it, went back to the VX and reconnected the rod and now my defrost is back and I can see where I'm going.
Again, the site and it's members saved me a bunch of time and probably a bunch of money because I didn't have to bring it to someone to work on.
WOOT!!
