When the car is parked in the sun for a period of time the odometer and speedometer will not work until the AC is on for awhile

This is a mechanical speedometer, correct? Not sure what would cause this to not operate specific to temperature. The only things i'm seeing that affect speedometer operation is the vehicle speed sensor, wiring or the cluster itself. Get to testing components when the problem is occurring.
