Re: cruise control and speedo
As far as the cruise, I have heard a bad clock spring behind the steering wheel can cause problems with cruise, horn and other steering wheel mounted buttons. And for the speedo try doing a gauge sweep by holding down the tripometer button and turning the key on then press it one more time and it should sweep gauges. After they sweep and go back to zero turn the key off and you should be good to go. See if that does anything for you.
