In my 1987 300TD I'm having some Comfort control Issues. the First being, I do not get air down by my feet, The Second thing being, my Defroster for the front is hot. the Climate wheel has no effect on it's temp when running and the fan speed selector also has no effect on it. despite this, when I have the climate control set to Floor, the Climate wheel works and adjusts the temp quite nicely, The Fan speed selector Works just fine... What could have messed up this time around?
