360 heater issue?

First and most probable thing to check is that your coolant level is to spec.
Then make sure that you can hear the servo motor buzzing when you move the temperature control knob from cool to warm. Check that there is no air in the coolant system either (I don't know how you can check that other than just bleeding it for good measure. The only way it should have air in it is if the level dropped very low, then fluid was added, but an air pocket remained.)

Those are the two or three most basic troubleshooting steps. If it's neither of those, then I would say that it probably needs some real diagnosing.

 

I'd second the check on the diverter flap that controls hot/cold air mix. I can hear a faint noise when switching from hot to cold in the 360. I suppose that even if you hear the motor, the flap might still not be moving all the way open/closed. This can happen in any car, not just a Ferrari. I had to get an actuator fixed in my F-150 recently for the same issue.

 

Was your coolant flushed recently?

 

Do check the coolant level. If it's okay, however, it could be the climate control unit, which is also responsible for the A/C. The unit was faulty on my scud and was replaced by the dealer who sold me the car. Before that, I was quoted $2600 for the unit by my local dealer.

Check out this thread. Although it's about the 430, it may be applicable to the 360 too:

Did this get fixed? I'm having a similar issue.
Thanks!

 

A failed re-circulation pump would also be a possibility if you're drawing a blank with the various suggestions above.

Once the ignition is turned on you should be able to hear a gentle hum from it if you crawl in under the car and put your ear close to the floor.

 

So, I get heat from the foot vents and windshield vent. Blast of cold air from the dash vents. I've been told there's valves in the boot behind the panel cover closest to the dash. The report is, these valves are somewhat problematic. Thoughts anyone?
Thanks!

 

I had the same trouble when I got my 360 Spider one year ago.
I've done 2 kind of things :
- Electrical contact cleaner on connector of the different component of the heat control module
- Multiple switch between maximum left and maximum right of the button of control panel.
and now it's working well for one year

 

Was that from the dash controls, or from the boot area? If from the boot, was it difficult to uncover the relays, etc?

Only the ones under the dash.
