I have come to the conclusion that jeeps are extremely cold without there fast acting heaters! My heat/air conditioning is out.... it started with with jus my control unit, i was unable to adjust where to send the heat/ air conditioning. so i went out bought a new head unit but nothing happened. now my heat and a/c is totally gone i can't control the amount of heat jus nothing comes out. any ideas on where i should go from here? i am guessing and hoping that my ground or power source is bad so thats where i am heading so far...

thanks
