I just realized yesterday on my Yukon Denali 2003 that A/C in the front is cold but the rear blowing Warm or sometimes hot air. For 2-3 minutes it blows cold air in the back then back to heat or natural air. Any reason why?? It has 93K mileage

    My 2003 Trailblazer is doing the samething. Did you ever figure out what was causing your problem?
