The speed part of the speedometer still works. The mileage part has stopped working. Also the trip part. Do I need to replace the complete speedometer or just the cable?

Hello and thanks for donating

Does your Cougar have the standard or the electronic instrument cluster?

The instrument cluster is standard analog.

Thank You

The speedometer and odometer/trip use the same sensor to work, it is the speed sensor mounted on the transmission. I find it hard to believe that this would be the cause here since your speedo is still working. The odometer/trip is inoperative but leaving the speedometer operative, that would point more towards a wiring issue at the back of the cluster assembly or a faulty cluster assembly itself.
