Yes a problem,like it doesn't work,99 Cherokee with air.The dial selector seems to work ok on all settings but defrost.When you select defrost,hot air blows out real hard from the side widow vent but nothing from the defroster vents.In fact it is really loud blowing out the side vent.The AC compressor also cycles when the outside temp is very cold. My other 99 Cherokee's AC does not cycle when the outside temp is below about 35 degrees.Just a comparison between my two Jeeps.
Obiviously something is wrong,maybe a vent flap broken? Asking for opinions before I tear into this,thanks
