Mk5 Mondeo (2014) - from time to time, the electrics pretty much shut down. Air Con; Sync/console; windows. I've also had it where the stereo was stuck ON and wouldn't accept any input from touchscreen, although the steering wheel controls managed to lower the volume. It happens a couple of times a week and my biggest concern is that without aircon (or windows!) the windscreen mists up fairly quickly.

Any ideas on how i can do some sort of reset on the electrics? Should i disconnect the battery, if so - any particular order for terminals?

Thanks in advance folk.
