Hi!
I have a F-type 2016 and my air condition work perfect for approx 5 minutes then only warm air comes...after I deletet fault codes it work again for some minutes then same codes comes again.I have fault codes and these are:
B1412-96 Quiescent relay box (Permanent)
U0194-00 Lost communication with the digital audio control module B (Intermittent)
B13C2-49 Windshield misting sensor (Intermittent)
I read in some forum that it could be the relay box that placed in the back luggage?
Some Ideas???

Have a good day?

The first thing to do is to fully charge the battery, to eliminate that as a possibility.

 

And if you're still on the original battery, it might be due for replacement by now!

 

Magnus: please provide information about your car: model? Model year? Engine? This information is crucial in providing any useful help.

The responses you have been given (to this point) correctly focus on battery voltage supply. The reason for this is that an overwhelming number of APPARENT defects are cause by one simple factor: insufficient battery power. Therefore for ANY problem related to any electronic part of the car, the first thing to verify is the battery condition. Insufficient power to the multiple electronic modules leads to malfunctions and fault codes.

BATTERY FIRST!

 

Hi Magnus,

One possible cause of your symptoms is undercharged (or overcharged) refrigerant. It would be worth having your system checked for proper refrigerant pressures on the high (compression) and low (suction) sides of the system. The A/C tech can also check to see if the compressor is shutting off due to an electrical issue apart from a low- or high-pressure condition.

Cheers,

Don
