Many years ago while working at a Volvo dealer, the owner took one of these in for repair. I called Volvo dealer support and they said there was no parts or literature available from them, but gave me 2 phone numbers to dealers that might still have parts. I called the one on the east coast and got a parts woman who was fantastic. Set me up with everything I needed and gave me some tips. You might want to call Volvo and see if they still have those numbers.
