First, thanks to those of you who assisted me with the diagrams I needed. It was exactly what the doctor ordered. I took the car to Volvo and verified that the contoller board did in fact need to be replaced, and it does. Unfortunately, three years of unemployment and total disability make it impossible for me to buy a new board ($290.00). I am selling the car and would like to fix this problem before I sell it so that the car is truly in perfect condition. Does anyone know of a wrecking yard that specializes in Volvo's? In the South Bay Area, CA or anywhere in the USA if they will mail it to me? I am desperate to take care of this problem ASAP as rent is due so any assistance you fine people can provide would be much appreciated. Thanks again for the help in diagnosing the problem.
