Hello all! I'm new to the forum and a fairly new Nitro owner. I have a 2007 Nitro SXT Manual transmission, 3.7L and am having issues with the HVAC climate control unit. The Unit just quit working. The ac has never blown very cold. Big disappointment since I live in Central TX and summers can b triple digit and humidity, ridiculous. Only the fan or blower on the Unit works now. The blending doors are nonfunctional as well. Through process of elimination, we have narrowed the problem source down to electrical. Possibly the a/c switch, i.e.,climate control unit. According to an electrical schematic my bro found online, there is another power test point that goes to the climate control unit, S216. We have been unable to locate this point to further narrow down the problem. Any ideas?
