Peougeot boxer switch fault

[chrism1969]

Any one know what this is. I have a motorhome, eldis 155. This is on the Peugeot boxer frame. In the centre switch’s below the heater dials I have a flashing switch light even when the van is locked, empty etc. The switch is the rear screen and wing mirror demisters. I don’t have a rear screen and possible it might be linked to the wing mirrors. As it on all the time. It killing my battery. I looked for the fuse but it’s not in the box next to the steering or under the bonnet. Any one have any ideas. Is it a fault. Any advice would be appreciated

Regards

Chris

The "heated rear screen" button provides power to the heated wing mirrors even though you don't have a heated rear screen.
Does the flashing continue when engine running / driving?
If not, it could indicate there's insufficient power from the battery to operate the heated mirrors. This could be as simple as a loose / corroded connection so suggest you remove the switch panel complete with surround and disconnect / reconnect the cable connections.
If it also occurs when engine is running it could be a more serious problem.
Believe the fuse for the heated mirrors is in the engine compartment fusebox and is F30 at 15A.
