anyone have an 1984 Vanagon owners manual?

I have 4 sliding controls for the heat in my 84 Vanagon wagon and also an overhead set-up with a switch between 2 knobs ---anyone have an idea on what is what ?  
Then there is another switch beneath the rear window defogger---looks like a glowplug symbol on it----that one needs identification also.
Any help is appreciated.
