Does anyone have experience with this? New to me 2010 LHD California. Now that the days are getting cooler, I tried my heater out and although you can roast marshmallows on the passenger side when set to maximum, the driver's side only blows cold air. In dual zone mode, I can adjust the air temperature coming out the right side vents by moving the passenger side dial but the driver's side dial has no effect on temperature on my side. In MONO mode, the drivers side dial controls the passenger heat (so the dial works), but does not change the driver's side temperature. Vents are open, and the problem is not one of airflow but rather just temperature. The car is up to operating temperature when I am testing this. Coolant level seems fine. I'm assuming it is a blend door or damper motor issue, but I don't know where that might be located. Coincidentally, I had something similar recently in my Nissan Titan, and that was a software fix (there was a TSB on that). Anything similar for Ferrari here? A quick search did not find anything. Does the system use only one heat exchanger and a blend door, or does each zone have its own heat exchanger? Is there anything else that I can look for (fuse, wiring connector), or is this going to be a dealer issue? Hopefully without disassembling the dash to access! Thanks for any insight you can provide to help!
In typical Ferrari fashion - two days / three drives later, it's working fine. ???????????????????????????????????? No idea what changed. Mixing door sticky perhaps. It was bad for a few days, and suddenly from the start of the drive (as soon as the engine warmed up), the heat flowed freely. The solution is obviously to post the problem and embarrass the car into submission.
