I am trying to sell my truck and I finally have to address this issue. I have a 1998 Chevy S10 with a broken odometer (used to flash "matrix" style, now is just blank), broken speedometer (always 10-15mph slower than actual speed), and all the gauge warning lights go on and off randomly (the "Service 4WD" light is on most of the time even though the truck is 2WD). Any suggestions on an easy fix for this? I have heard that it could be cluster which would be expensive. I am hoping to get this fixed relatively inexpensively. Thanks!
