Hi,

I've got a Mk2 Focus RS. 2010 plate.

I started my car the other day - and noticed that the Sat Nav/Stereo/Camera didn't switch on. no power to it nothing - this includes the Power supply to the climate control as it's all built in.

I initially thought a fuse could have gone - so i checked them and nothing - all metered and correct. then i noticed that the interior lights aren't working either - little confused as to why they'd be on the same circuit...

Has anyone got any ideas? or experience in this issue? I'm thinking it could be a relay of some sort - but not sure if the relay would be replaceable or not...

Neither of them come on when the car is started = which there are no problems doing - runs fine - everything else works fine (headlights/speed/turbo gauge/indicators) just the stereo system and interior lights....

Any ideas would be greatly appreciated.

Thanks.

Bump.

It could be the battery saver relay or the power to it.

Check for 12v at fuse location F104, if no 12v here check F4 near the battery is good (60A fuse).

Do you know where the battery saver relay is? what happens when the ignition is on - i'm assuming the ignition would by-pass the relay?

The relay is shown as an internal component of the passenger junction box (not replaceable). If it was replaceable it would be shown with a relay number and connectors, it is just drawn as part of a circuit so its internal.

The ignition does not by-pass the relay.

From checking the wiring diagram all power you have missing comes through this relay, either the relay is not switching, there is a bad connector from the junction box to the wiring harness or the 12v feed is missing.
