I just bought a 1993 Bonneville SSEI in excellent condition. The only problem is the radio volume **** is broke and the radio is stuck on low. This wouldn't be a problem except NONE of the steering wheel controls work either. Anyone have any ideas where to start trouble shooting? I don't think fixing the buttons on wheel would help since ALL are not working, so figure its a wiring, fuse or radio malfunction. Lights on steering wheel control buttons are working and horn works ( dont know if that matters) Not sure if there is separate fuse just for steering controls or if its in panel located under steering ?

Moved to Bonneville specific forum for better visibility.

I'm new here, how do I locate that bonneville forum to look around?

found it, thanks
