Hi All
When I put the car heater on and don't use the fan, warmth comes
through the vents when on the fresh air mode. However when I put on
the fan the Air Conditioning (A/C) light comes on and I feel the loss
of power that happens when I am using the A/C. It appears that when
the fan is on, the A/C is also on and I therefore cannot opperate the
car heater with the A/C automatically comming on.

Does this sound right?

Thanks
David

In my experience it's normal for the compressor to come on when using the
defroster, but not the heater. What happens if you try to turn off the A/C
while the fan is on?

Thanks for the response Victek. I will check - perhaps it is coming on
with the defroster only and I am assuming that it is the same with the
cabin heating - I will get back

You should have a separate switch for the a/c (the button that has the a/
indicator lamp). You should be able to use this to toggle the compresso
on or off regardless of any other setting of the system, presuming th
controls work similarly to the U.S. controls

Thanks Victek and hyundaitech

It seems that the defroster is connected to the A/C as Victek
suggested. That is; when I use the defroster with the fan on then the
A/C comes on automatically - the A/C control lights up and cannot be
overridden and turned off. As soon as I change from the defroster to
the cabin heater then the A/C light goes out and the compressor
dissengages

So thanks for the info. I now know more about defrosters (which we
call demisters) Here in Adelaide, South Australia, yesterday was the
coldest night in over twenty two years with the minimum temp getting
down to 1.6 degrees C (35 degrees F) which created a frost on the car
widows - My 20 year old son had never seen this before.
Thanks
