B9 2009 secret heating function?

Well the best way to find out if you have one is to look for it, it will have a multi plug going to the end of it.

Maybe one of the others that have the heater could post a picture or give a description of where it resides.

If someone could show me where I should be looking and I don’t have to remove much to have a look that would be great.

The heater is  Item #4  in the diagram, it looks like the multiplug will connect to it on the left hand side (passenger side)

Here's a twist, I retrofitted heated mirrors to my B9. The heater control panel didn't have the heated rear screen / mirrors button but I discovered that the microswitch was actually in there and that I simply needed to modify the blank button to make it into a real button. I ran the wiring from the BSI to the doors and got the mirrors heating up.

Just a few days ago I was plodding along of a frosty morning and I remarked to myself that the van had heated up remarkably quickly with warm air coming out of the vents after only a couple of minutes. Having read another thread recently about a mystery auxiliary heater I wondered if maybe I had one that was only working intermittently or maybe was OAT triggered. I have just realised that it was the newly commissioned button for the heated mirrors that has made the difference.

So there we are! My van was built with an electric supplementary heater (that works really well) and no way to turn it on!!

It's a great piece of kit once you know it's there - and have a means to turn it on! I use mine all the time now.

at -12C i put the heater on windshield, max warm and speed 3 in about 4-5mins the ice on the windscreen had melted and i cleaned the water with a towel
very nice feature! is like having a real heated windshield!

also for a diesel engine gets at 90C (normal engine operating temp) very quickly! almost like a gasoline engine!

hi, how did you modify the blank cover, i have a 2014 enterprise van with heated mirrors fitted but i cant use them, it also would be even better if i could demist or de-ice the windscreen faster as well, thanks
