Technical Heater is draining the battery!

[Breakingfree24]

Help! If I don’t drive my 2012 fiat 500c for 24 hours the battery is dead! Local garage have confirmed that’s it’s either the radio or heater draining the battery. Disconnected the radio but battery still being drained so has to be the heater causing the issue. Does anyone know which fuse relates to the heater as I could remove it if the vehicle is not used for a few days? And/or does anyone know how to solve this problem?? TIA.

I think it's F08 - 30A under the cover in the engine bay.

If that solves the drain, then you could have a dicky resistor on the fan switch. They're about a tenner.

What about the Blue&Me module? It's a known source of issues in this regard.

Radio, theres the clue, Bluetooth yes? Then module faulty

My thoughts too. I doubt very much it's a heater issue, but the Blue&Me module is a hugely likely culprit.

You'll need to physically unplug the connector from the module to check this; AFAIK, there isn't a fuse that will completely disable it.

Interesting, I’ve never got to grips with how the Blue & Me works and therefore never use it!

Module is usually in the rear passenger quarter panel beside the seat, you need to remove or un clip the trim, and physically unplug the module, this should fix the drain but may leave the mileage flashing if it does then Proxi alignment will fix it( with a laptop)
