I have had troubles with the smartwheel on my HR. You can be driving down the road and the wipers will come on and won,t shut off, the horn will honk, cruise will quit etc. From the reasearch I have done you can check all the plugs in the harness in the steering colunm for loose but in most cases it is caused by the smartwheel controler box. Some are located in the outside fuse panel below driver seat, mine was in the dash behind the am/fm radio. I have seen where some others that have had problems have unplugged the controler and replugged it . I guess this reboots it. If you google smartwheel they have an informative site. Hope that helps.
