So my wife went into a ditch and bounced out. The fan had no issues prior. Now, the fan starts upon cold starting the engine but does not engage when the temperature rises. You can manually spin the fan, but it is not free spinning as there is resistance.

Good morning.

The fan clutch may have been damaged when it went off the road.

When it went into the ditch, the fan may have hit the shroud and damaged the clutch assembly.

I would replace it and make sure there is no update for the ECM. It does control the operation of the clutch.
