I totally agree here.. You see.. It looks like they are not allowing the valve here to mix to produce heat. Maybe there is something wrong on the chrysler.If you are talking about your Nitro, Chrysler uses an electronic mixing valve, to control the temperature entering the cabin. There is a small electronic motor that moves this valve, via a plastic gear. Sometimes the motor fails, and sometimes the plastic gears can strip. If you turn your control valve from cold to hot, or hot to cold, and you hear clicking, the gears are probably stripped, not allowing the valve to mix. If you turn the heater fan down, you should be able to hear the motor - it should be on the passenger side, behind the glove box. At least, that is where it was on my Jeep. Good luck.
From a Factory & Recall perspective it was 2007, Nitros first year in production had numerous problems, but it's best sales year by far. By 2008 most issues had been addressed in production but future sales had already been damaged with Recalls, Reviews, Word-of-Mouth, from its first year. As far as design faults they remained since no real changes were ever made from the first years model through the end (2011). For myself I am still pleased I ordered my 2007 R/T, but thanks to info here it received every recall and TSB I saw, by my Dealer all under warranty. As in most cases the final year of 2011 production must have been the best year to have purchased a trouble-free new Nitro!Is it me or do the majority of nitro issues occur in 2008 models ?

When one of the speeds stops working. 9 times out of 10 it is the resistor. This happened to me on both my Jeep Liberty (2x) and my Jeep Commander.Funny you mention this, my blower fan just stopped working in hi. works okay at the other speeds. Is it the switch or this resistor you mention? are they computer controlled? another odd thing happened a couple of months ago. came out of home and popped the tailgate. the radio started playing...odd!!
