Hi all

I am looking for some help I have an electrical fault on my focus 1.6 titanium it is an automatic and the following faults are showing,

The rear heated screen stays on

When I put the car in reverse I get a transmittion and engine fault appear even though the working fine

Stereo cuts out or won't come on

Screen wash pump won't work

Fog lights don't work

Alarm triggers but does not sound

Central locking can be tempramental and appears to short the system at times

I have been advised that it sounds like a gem module problem and is a matter of basically rewiring the car does this sound familiar to anyone and if so does anyone have a wiring diagram to assist with this?

Thanks

Gem module is the actual fuse box inside the car. It's simply a case of unplug old one and fit new one. Plugs are easy fit and keyed so easy to do

might be worth popping on the gem module and looking for any sign of water, if nothing then reseat all the connectors back in to GEM.

there is too much going on that points to GEM for it to be a coincidence. course there might be shorts but one thing at a time :)

Check fuse F12 (40A) and also check that it has 12v going to it.

Also check F25 (10A) is good.

If all above is good try replacing relay R8

And check all the grounds...
