    So I finally am in the tundra nation and bought a 2012 tundra crew limited with TRD supercharger. I had a nice test on a 850 mile trip back from from purchase. When I test drove the truck, everything seemed to be fine. All the modes work, all vent changes happen. On the drive home the ac was blowing cold, but my leg started to get warm from the console. Well it turned into really hot and was uncomfortable and my drink was warm. The rear vents are blowing hot air. My first thought was Ac actuator motor, but all the changes happen when going through different vent positions. Is this still the problem or would it be something else?

    Check the mag/clutch relay, they go bad frequently in Toyotas

    It’s a relay in the fuse box under the hood. I’ve had to replace it in every Toyota I’ve owned.
