Just bought an 89 C3500 last week.
The odometer and tripometer both don't work. The speedometer only works occasionally.
All the other gauges - oil pressure, temp, voltage, and fuel - all work fine and seem to be accurate.
What could be the cause of the odometer not working and the speedo only working sometimes? Is this likely to be a bad gauge cluster? Bad wiring/ground? Bad speed sensor?
What specifically controls the odometer that I could check?
