    If I turn my heat or Ac set to high and turn the vehicle off, the next day when I start the truck, everything is off. I have a remote start on the vehicle and it’d be helpful to be able to set for heat and defrost before getting out so that they turn on when I remote start in the morning. Any ideas on how to fix this?

    Nothing to fix. That's how it was designed.

    That sucks. But thanks, I’ll stop looking for blown fuses.

    It should resume to the last known setting.

    I see it’s a limited.. so you have auto climate control.

    If it isn’t or doesn’t turn on there is most likely a problem with one of the servos or a problem with the climate control ecu.

    Op here. Yes. Working properly, the climate control should retain settings. What I found was that there was a physical wire caught in the gears by the drivers right shin. The gears control the doors of the climate system and that wire jacked it all up.
    I took it apart but for the life of me can’t get the whole thing synced again. Need to take it apart and give it another go.

    Does you defrost and/or A/C retain?

    I had this issue on my 10 limited. After countless hours searching and working with a Toyota master mechanic who became very involved because he was determined to find a solution.

    The end result was the climate control ecu had malfunctioned causing the servos to move at incorrect times and bind.

    The unit extremely expensive and basically the whole dash had to be removed to access getting it out, so I passed on fixing it.

    Thanks Scree
    Can you elaborate a little?
    My 2010 Tundra Crewmax Limited has retained it's climate settings for 10 years
    I killed my battery last week leaving the bed light on
    Since restarting the truck using a battery charger I have to manually turn the climate system on each time I turn the ignition off

    Wow!
    Hope there is another reason
    So you've been manually controlling your temp after every restart?

    That's one way to solve the problem
    Hope there's a simpler way

    Need some advice
    As mentioned in previous posts, climate control not holding settings in memory
    Now both heater and AC working at the same time
    Dash vents blow cold (cool) air
    Center console vents blow hot air
    Taking off on a road trip into the heat in 2 days
    Any advice on how to deactivate the heater at least temporarily?
