Just got a used dual digital climate control unit to replace my old one which was beyond repair, and have never noticed there are two different types of recirculating buttons.
My old E36 saloon had (3rd button down on the right) a three arrows in a circle icon, and the unit I have just purchased also has the same.
The unit that is broken I have only just noticed, has two three arrow circles and two led's on the same button, the left side has an A in the circle.
When I fitted the unit, there was an extra wire/socket which the replacement unit does not have.
The replacement unit does work, but the temp operates in the opposite way ie 32.0 is cold and 16.0 is hot !
The aircon doesnt seem to work very well but it may just need re-gassing.
The fan speeds operate normally as do the top vents/middle vents/footwell vents buttons.
I cannot understand why the temp works the wrong way, surely its not just because of the extra recirculating wire/socket not connected ?
Any ideas ppl ??
