I have a problem with my 2001 Jeep Grand Cherokee LTD in the sense that the blower only blows cold air, no matter if I turn the temperature all the way to "Hi". The A/C works fine and the cooling process seems to work ok. I have contacted Jeep and they have said that it appears to be a "very expensive" fault. Since I am not very mechanically inclinded, I wonder if there is anybody that can shed some light as to what this problem could be.
I have checked the previous threads, I have done the diagnistic check ("done") and I have performed the core heater check (No mist or smell present).
Any advise would be greatly appreciated.
