hi to all, I need help with electrical problem on my 03 x type. the a/c and recycle, all heater flaps, rear and possible front heated screens and alarm have all stopped working. I have checked all fuses and relevant relays and they all seem ok. I have checked where possible earth connections and  seem ok. any help would be very appreciated. many thanks for reading my post.

Welcome to the club  and I think the first thing to do is  to check your battery --check its age and consider a replacement--????

Tony,

Welcome aboard!

That is quite a list - all of which, (at a first glance), are totally unrelated other than they share the same power source - your battery, (as already pointed out by Frank)!

I note that most 'modern' vehicles, (both cars and bikes), can suffer a whole host of 'esoteric' electrical problems when the battery begins to fail but it is also worth re-tightening the battery terminals as the continuity, (betwixt the battery terminals and both the earth and positive leads), can decrease, (due to both corrosion and oxidation), and this will only start to show up as the current draw on the battery increases, (ie - when the vehicle is running and when high current devices are switched on - such as your heated windscreens).

Just a thought!

Martin.

many thanks for your thoughts on my problem, I have had battery off for a good charge, it went down to half amp and showing 13 volts 24hrs later before I refitted it. I need to get to garage so they can test it properly but cant drive with screen misting in cold weather so will have to wait. by the way, both front seats heat up and move as they should and alternator is pumping over 15 volts. thanks again.
