Climate control system question

Hey y'all.

 

Just a quick question - on my 2015 Silverado with Dual zone climate control - each and every time I want to turn it on, either by pressing the button in the center of the fan control knob, or by rotating the fan control knob, the system automatically turns my A/C on, whether I want it on or not!

 

I don't want the extra drag of the A/C compressor running when I want heat out of my truck, so my question is this, is there any way I can stop the system from automatically and constantly turning on my A/C every time I turn on the HVAC system? As it stands I have to turn it on, then manually turn off the A/C EACH TIME, which is annoying.

 

Any help would be appreciated, if I have to live with it as-is I will, but it's annoying to have to constantly turn off the A/C each time I turn the HVAC system on.

 

Thanks,

G

The auto system turns the light on but it is not constantly running as you would expect. GM is not the only auto climate that does this as most do the same exact thing. Safe to say, just because it is on does not mean it's running. The computer will only cycle the compressor when cooling or de-humidification are required.

 

I thought the same thing as you but did some research and it put my mind at ease.

The system should only turn on the AC light when the compressor is running. That would seem like a lot better way to handle things. I guess as long as that compressor is off, it is OK though.

Ok thanks guys. Yes it's very annoying so I'll probably just keep manually turning it off.

      The Peckish Synapse

      You're better read than that Atlas. 😏   British science fiction writer Arthur C. Clarke formulated three adages that are known as Clarke's three laws, of which the third law – that "any sufficiently advanced technology is indistinguishable from magic" – is the best known and most widely cited.   Stribeck and the pivotable Hersey Number isn't voodoo nor snake oil. That part is physics. It's what marketing and bean counters do with it that is snake oil and voodoo.    Stribeck is the relationship between Hersey and the Coefficient of Friction. Within the Hersey Equation if viscosity and viscosity is 'Dependent' on.......heat.......and.......viscosity index or the temperature to viscosity slope.    Specifically Hersey is the viscosity AT THE TEMPERATURE IN THAT LOCATION FOR THAT SLOPE.   Hydrodynamic lubrication exist when the film thickness in the location is 3X the Ra roughness of the surface. This is irrespective of the hardness of the substrate. To obtain that thickness X viscosity is required for Y velocity at Z load. That's a lot of moving parts. It is also impossible to maintain in an ICE but nearly possible with a turbine under constant load.    What does that mean? Error heavy and operate light. Wear is inevitable but the rate of wear and the milage obtainable are a function of prevailing conditions and HABITS. The only penalty is viscous drag and at fractions so low as to be well worth the effort. Double the life, half the manufacturing carbon foot print. Greed is the only impediment.    The materials generated by SwRI are the RESULT not an estimation or a hypothesis.    Don't delude yourself sir, EV's have as many pitfalls as ICE's. We just don't know what they are yet and it will take longer to sort as MARKETING and GREEDY CEO's have had more time to polish the turd they are selling.

      You can always count on greed to prey on ignorance and stupidity.    Friend bought a 2019 Ford Flex and asked me about using Valvoline R&P 5W30 in it. Told him give the miles on it and the fact it wasn't yet using oil that it was a good plan. He uses a Valvoline quick change shop for his oil service.   First they tell him that isn't the oil the OEM recommends. He told them he didn't care what the OEM thought. Then they floated the, "But it will void your warranty"    His reply was it's a 2019, there is no warranty and informed them their knowledge of the law was lacking.    Then they tell him 'But it will ruin your motor"!.    Mine to ruin he says. Finally they give in and charge him 150% the semi-syn price    Point it the brainwash is so embedded that even the service industry is drunk on their swill. The public is right behind them. Echoing the same lies on every forum and media platform. If the end goal is indeed EV then I'd say that ship is about built.

      Diesel hit $6.00 here today at the truck stop.   Payed $2.79 for E85 today too.
