Hello, I have a 1992, w124 300E, and I am wondering, are there any warm air be supply to the vent on top of the central console, as I only have cold air come out from it, what ever I set the temperature setting!!!

Beside of that, should there be any air supply to the temperature sensor hose, which mount on the interior lighting console, on the roof of the car?? and what and where is the 'supplier' of it??

and also, where is the circulating pump for the ventilation???


Thanks in advanced!!
