Help me troubleshoot my S90
 

I have a few issues with my '98 S90 which I'd like your help/advise about...

• The first thing that comes to mind is that my cruise control stopped working. I won't turn on anymore. Any ideas where to start looking for a fix?
• My car develops a terrible shimmy at speeds over 70mph specially when turning to the left. I've ordered new tires and will install them soon. Is there something else I should look for? The wheels appear to be straight and no loose components appear readily in the suspension and steering mechanism.
• Several lights in the console around the gear selector are inoperative. Where to find instructions about how to remove the panels to get to the lights?

There are other minor issues and probably more will develop in time. However, these have captured my attention for now. I've looked in the internet, google, Utube, etc. with no results I could use. I'd really appreciate your help with this.

Thanks!
