    Same exact problem with mine although it’s not the dual climate control

    Glad I live in Texas until I get this figured out, sucks when riding my Harley in the snow is the same as riding in my truck heat wise.

    So I took mine to the dealer as my temp gun has died for good and my hands can only feel warm or cold, and not with a great degree of accuracy either. Problem is a plugged heater core. I don't have the time with work at the moment to tear it apart so they are doing that and a couple of other maintenance items that need to be done. The darn labor charge for 9+ hours for them to do is going to suck big time however. :puke:

    Replacing the heater core is a 1-day or weekend gig if you have access to a A/C shop that can evacuate your A/C system. Odds are, if your heater core is done, your Evap is probably clogged up as well or not far behind especially in a 6 yr old system. Might as well replace both while the HVAC is out for a core replacement.
