Default Is the auto climate control lowest setting of 65 degrees F too hot for you?

My 08 WRX is the first car I have ever own with an automatically controlled climate control. For the last 6 weeks of ownership the climate control has been an annoyance that distracts my attention from the road.

It works perfectly well, when I set it to 65 deg F it keeps the cockpit near that temperature. However, I'm too warm-blooded for 65 deg F. In the winter I am wearing clothing that keeps me warm, I can't just remove my clothing when I get in the car, that would be frowned upon. With all my previous cars, I just set the temperature manually to give just enough heat that I am comfortable. I also like to keep new air circulating in the cockpit, so turning off the air flow is not an acceptable choice for me.

I want to hack this car so that the automatic temperature control dial (knob) range of 65-85 deg C is modified to have a wider range of perhaps 55-85 deg C.

I have a suspicion that the climate control is all computer controlled. There is going to be a micro-processor somewhere. Can anyone tell me where this processor is, and if there has been any work done by other members to this processor? I thought it would be prudent to ask this forum before I start ripping apart my new car.

I have a backup plan if the processor can't be modified. Plan B is to modify the temperature sensor itself so that it reads 10 deg F higher than normal. Depending on what kind of sensor subaru is using, this may be a very easy modification (adding a resistor in series) or slightly more difficult. Does anyone know what kind of sensor is used?

LOL!! Seriously I couldnt agree with you more. All that trouble because the guy is thermostatically challenged.

yep it's true at 65 it is a little warmer than I expected. I just turn it off. If you put the AC on however it blows pretty cold.

i can just picture you driving down the road sweating puddles and not even thinking about turning the heat off for a few minutes.

umm, just take it off auto. It's not the best system in the world. You can manually adjust the fan speed, where it exits, and the heat. No different than any other system

wow way to tear the guy a new one cause he asked if theres a way to mod his climate control

heaven forbid if a question was actually answered or led to some discussion which was actually helpful to someone....

anyway....on subject:
i really doubt you'll be able to modify(reprogram) the processor....your best bet would probably be to modify the sensor like you said. most likely it's just a thermistor....im not sure exactly where the sensor would be in your car....usually it's located near the control panel on the dash....underneath a little vent in the plastic...

Hey you're the first guy to add anything useful on this thread. The previous 17 people found satisfaction in adding nothing but still taking up bandwidth.

You're correct, the sensor is behind some slots near my right knee when i sit in the drivers seat. I'm hoping that with this post someone might know the sensor type. if not i'll just have to do the investigation.

And to answer all those idiotic responses: Who wants to open windows or turn the temperature control to full cold, then revert back to heat, perhaps every 5 minutes? This is annoying on a long drive. An old fashioned non-auto climate control would have worked very well in this car for me.

you could add a resistor in line with the sensor wiring, but depending on the output of the sensor, i.e. {if the temp goes up the resistance goes down (NTC) or if the temp goes up and the resistance goes up (PTC)} that would work fine if you knew that, but you could go the other way and effectively raise your operating range.
2. another way to fix your problem would be to fool/cheat the exterior temp. sensor. and make the processor think that its colder/ hotter outside then it really is, it will compensate more with the auto setting. this would be easy to do, just measure the resistance at a few different temps. then just replace the sensor with a specific resistor and you have fooled the computer. BUT your exterior temp sensor read out will show all kinds of weird readings

thats all i can think of real quick. i'll do a lil research and see what i come up with!!

Disagree...though climate control is nice, it is no good if it doesn't control it to what you want.

If I bought a brand new car, and the AC/heat didn't work, I'd be sorely pissed.
