Ok. I’m super over how these HVAC temperature controls operate.

While not on auto and temperature set on a constant, this stupid system constantly is changing the temperature. As you all know, it will go from blowing ice cold air to liquid magma as it pleases.

Even changing the temp 1 or 2 degrees can make it going from one extreme to the other. I’m over it.

What I’d like to know is how can we fix this issue on our cars? I just want the “temperature” dial to be like cars have been since 1932, 0% heat flap to 100% heat flap.

I’m assuming this will take some BCM tuning, which I’m ok with. But I know I’m not the only person who this annoys. Other options I can think of are disabling temperature sensors, but I don’t know how that would impact the actual operation of the system. If it goes to a default then that’s perfect.

May want to hook the car up to scan tool that will read the HVAC module and see if you have any trouble codes. I don’t know how well the 14’s controls the output, but I am well satisfied how the 11-13’s work. If they keep working for another 15 years, I will really be impressed.

i have a 12 and no issues

I second getting a scan tool or taking it to a dealer that can read commanded and actual actuator positions. Sounds like you have a screwed up temp actuator.

My 2011 doesn't do this either

There is nothing wrong with the car, the HVAC is just programmed like shit.

I guess that I should say that I’m looking for 14+ owners and their input.


Are any other 14+ owners who want to have their HVAC programming fixed or know how to trick the system?
