Message I've done quite a bit of looking around on this issue -- having intermittent speedometer issue. Sometimes it works, sometimes not. Speed sensor should be fine -- cruise works, odometer working. It's gotten to where the speedo is always running in the 100+ area. EVERY ONCE in a while it works fine. I pulled the cluster, pulled the speedometer to check for any corroded traces -- not seeing any. I can post a pic of the back of the circuit board if needed.

Do I just need to replace the speedo at this point? Or if there are no visibly bad traces, do you think maybe it just comes down to bad harness connections?
