I just got a new '12 Prerunner TRD Sport V6 auto, to replace my '05, which was getting way up in miles. I love the new truck, but yesterday I drove it up to the desert, and discovered a serious annoyance with the heater-A/C controls. In the '05, the hot/cold control, the compressor, and the recirculated air were all driver-controlled. With the '12, the controls look the same, but the compressor and recirc are locked "on" when you dial the temp knob to coldest (or asking for no hot water circulation). I'm a little OCD, and I have this mental picture of a little bit of hot water seeping through the heater coils when all I want is unheated/uncooled vent air from outside.
MY QUESTION: Has anyone else disliked this feature, and/or have you done any mods to change it back to how the earlier gen II had it?
I will repost here with what I do about it. I'm an electronics tech and electrician, so I'll most likely be able to figure out a mod for it without disturbing the factory harness or affecting the warranty. But if someone else has, and I missed it in the search, thank you in advance
