Over the last few days the fan is running full speed as soon as the engine starts. Even with the AC off it still runs at 100%. Cannot get a dealer slot for star check until at least next week. Doing a search it looks as if it could be ECU, fan speed controller, condenser sensor, or harness. With the fan on full pelt the engine takes longer to heat up and is about 80 rather the normal 85-90.

Engine
V8 petrol op is normal but think climate control is not controlling as it should, colder than normal.

Not using the car as the fan may burn out.

When it goes on star will the fault be identified to a component.

Any info would be appreciated.
