Hi Guys, put some new batteries in my Aux heater remote for the winter and tried it out but nothing happens really. I've never seen it run since buying the car around a year ago and have studied the owners manual. I even tried the manual activation button within the car but nothing happens. Any thoughts on fault finding?

The car is a Dec 06 3.6 V8 Diesel Vogue.

Many thanks in advance!

I believe aux heating only activates over 15 degrees ambient. Is it the original fob? They do need pairing with the car and even if original may have lost pairing at some change of battery etc.

Not sure about the manual function other than the 15 degree bit above.

just a thought. 405 AB exec seats Baltic and Cirrus

89 Classic Cairngorm Brown

Park heating will only come in if ambient is less than 16 C. Cooling only if over 16 C. If you have changed the battery then, as suggested, you may well have to pair the remote again. First thing to try.

A forum search will explain how to.

Okay, the latest is I have put new batteries in the remote, waiting until the temp was below 16 deg C, pulled the fuse to resync but the result is nothing happens with the heating. I get a green light on the remote for a few seconds and then that's it.

Is there anything else I can do to get the system working? Nothing happens when I press the manual activation of the system in the car either

Thanks in advance!

Pulling the fuse doesn't seem to work on post 2006 cars , so find the receiver unit in the right rear where you will find it on the back of the mounting bracket and sync your remote by pulling out the power lead . 2008 MY Supercharged

Thanks Axle, but how do I find out if the FBH itself is faulty?

Have you tried running it from the display screen? John

Just re-read your first post. Suggests your FBH is broken.  John

Manual Button just goes green then red for a second and nothing happens..

Is there a fuse for the fbh just to check the obvious😎

Not sure if it's the same for your MY but on mine fuse 59, 20 amp.

PS. Passenger compartment fuse box. John

Just checked and fuse is fine Have no idea where to fault find next!

Update, pulled fuse 56 and then did system reset diagnostic test and now the fans are running when I press manual and via the remote. Does the fbh not turn on unless ambient temp is colder?
