I have a 2000 Saab 9-5. I purchased it used at the beginning of the summer and absolutely love the car. There's only one thing I don't like though. The car was rebuilt after an accident by the previous owner and everything looks and works good as new, except the TCS button doesn't do anything. TCS works but that's the problem, I hate using TCS, even in the rain and snow, and wish I could disable it. Does anyone know how easy or hard of a fix this is, or should I just take it to a Saab mechanic to get it fixed?
