1) The instrument cluster between the tach and speedo resets along with the HUD. This happens quite often, I have owned the truck for a month now and it has done it about 50 times. I did find a service bulletin: #18-NA-324. 2) The movable air control door hidden inside the dash seems like it 'sticks' and won't position itself properly for what is asked from either the touchscreen or manual controls. For instance, when I remote start the defroster is automatically set. That works fine; but in order to get ANY flow to the floor one must first select the combo defrost/middle area to 'unstick' the door. You can literally hear the door unstick and move. You can then select to the floor for air flow and it will work. 3) On a smaller note, the right rear door does close properly; it seems like it rubs on something during the closure process; I'm sure that is just a simple adjustment that I will get done at the dealer during my first service.
My 2010 Sierra Crew Cab has the automatic climate controls and a problem that may be more common than I think. The temperature on the driver side doesn't warm up no matter the temp setting while the passenger side seems to work just fine. I tried switching between Auto and Manual modes, doesn't help. I hear a click down by my feet which I assume is the blend door actuator for my side. What is involved in changing the blend door actuator? How do I know that's the problem and not the controller? Why do the fail? Do the plastic gears break or the little motor burn up? Any suggestions or diagrams of the heater box would be very helpful. Thanks.
I have a new 2015 LTZ dually with dual climate control, driver and passenger. Once in a while, without any discernible pattern, the passenger control knob will default to "HI" after starting the truck. Has anyone else ever seen this?
First time to post here... so my apologies for giving too little or too much info... Got a 2006 Sierra SLT Crew Cab Z71. Its just now getting cold enough for me to use the heat in the morning and for some reason it is acting crazy this year. No problems in the past. When my truck gets up to temperature I turned on the air and ran the digital temp number up 90 and nothing happened - air stayed cold. I turned the air off and then back on and it got hot immediately but 30-45 seconds later it returned to cold air. I repeated it a few times and it was hit or miss about 50/50 when the air would start blowing hot again (and it was hot - not warm so I don't think it has anything to do with the heater core). I have heard of the a/c being on and then going to hot but never the other way around. I do suspect that it wasn't actually going to a/c but to the ambient air outside the truck (40 degrees). It was like this on both the passenger and driver side - unlike when I hear of only one side acting crazy. Anybody ever experience this or know what is going on? How do I fix it? Can't go without heat - pretty soon I will have ice on my windshield that will need defrosting. Thanks in advance for the help!
