The speedometer in my 04 cavalier has started acting up. It will jump from 50mph to 100mph and stay there. I can pull the instrument cluster fuse and it will eventually reset. And sometimes when the speedo is acting up, the cruise control will not work. anyone else having this problem???
Could have a problem with speed sensor in youre located in the rear of youre transmission. Sometimes that sensor gets dirt & gunk road grime in it, In which causes it to give improper readings.
