I have AZC or automatic zone control dually. But in manual mode I set temp at 74 degrees and after 20 minutes or so of driving, the output of air gets cooler and cooler to the point that I must increase temp in read-out, most on passenger side. Jeep manufacturer is giving me a song and dance routine that such is the way it works, and so is the dealer where I purchased the vehicle and others to where I have had the vehicle diagnosed. Now I get the news that some flyer from Jeep/chrysler from May of 2001 states what I have been hearing from these dealers and so on. I think that manual is manual, the air temp must remain constant no matter what. What say you regarding this problem. Other owners with whom I have talked tell me that they never had such a problem and that manual for them stays at the same temp constantly. Thank you in advance for any feedback. I will contact consumer agency and better business bureaus until I get satisfaction. Manual is manual setting, not what the so called system dually interprets it to be, IMHO.
Thank you. M.
