Do any lights on the climate control flash? Any funny smells? I have not detected any odors or flashing lights. The air is cold for about 15 minutes and then nothing but warm air. Is there a way to turn the fan off completely until I figure out the problem because we have been having a bit of a hea...

I have a 2000 Cross Country V70XC. The air conditioning works fine for about 15 minutes then cuts out. The fan is on but the air is no longer cool. What, if anything am I doing wrong?
