Saab: saab 1992 900 s, e mail address, saab 900 s

Question
I recently purchased a 1992 Saab 900 S. I am having trouble with the lights inside the car, the seat heat and the roof will not come down.
The light come on and then go out and I have not noticed any thing that cause's them to come on or to go back out.
The hyd. oil is empty.
Where can I get a diagram of the wiring, and where should I start looking. thank you

Answer
Paul:
I am scanning in some relevant pages regarding the wiring to the interior lighting AND the heated seat. Can you send me your DIRECT e-mail address to facilitate sending the scanned in items as enclosures? Unfortunately, I cannot give you any specific advice except that you'll need to follow logical fault finding procedures with the help of the diagrams.
Which "hyd. oil" are you referring to?
