Is yours a climate control unit, if so have you checked for codes to indicate the potential problem? Search this forum it will be most helpful
as it was for my car.
Hope this helps

Fan doesn't blow? Or you can hear the fan going, but no air from vents? I have encountered some vehicles with slightly low freon levels that freeze up the evaporator core (into a brick of ice) when running for a long period of time with the blower on a low setting. Take it somewhere and have the pressures checked.

Need more info - what are the Controls set at? Can you hear the fan running? Does jumpering the Blower Motor to the Battery get it going again? Is the Compressor engaged? Is the big line exiting the Evaporator covered in ice? Can you see any ice on the Evaporator Core (remove the blower module on the left side of the case and look inside)? Do you get a big puddle of water underneath it after it's been sitting for 5 or 6 minutes?
