    Hi there! New to the forum and need some help. I LOVE my Tundra, but the a/c system is on the fritz. Thankfully the a/c compressor comes on when the button is pushed, but that's about it. When the system first comes on it is automatically at 72...I can change the temp numbers, but it doesn't actually do anything. It seems like all the blend doors are stuck. The air recirculation doesn't seem to do anything, nor the defrost, and while not an issue at the moment there is no heat when the temp is turned up. I got a code scanner on Amazon and here are the errors I am getting. B1497, B1424, B1421...screen shot attached. It looks like this is an issue in the 2nd gen Tundra, but I can't find squat about it on the 3rd gen. I've tried disconnecting the battery to reset the system but that didn't do anything. Oh, the truck is a 2014 Crewmax Limited. ANY HELP IS GREATLY APPRECIATED!!!

    Did you ever find out this problem. I'm having the same issues and haven't been able to find out much. Thanks
