Trouble with AC Button

[DangThatHurt]

New guy here. 2000 LX470. Climate control issues. The AC will not turn off. It is always on. I do not have a cooling drawer nor a cooling button to push. The "Defrost" button doesn't do anything. The recirc/fresh air is stuck on in "Auto". Any advice?

turn the HVAC console off, and then disconnect the battery for a few minutes. see if that gets it out of that stuck state

Those buttons wear out and you really gotta press them with some gentle force to react. There is a recent thread on here with a fix that requires some disassembly and touching up the backside of the button with some conductive paint.

Thank you for the input. I've tried the battery trick and it did not work. I've ordered the button repair kit. Thank you all.

I posted about CaiKote not too long ago. Not sure if it has been posted prior or since but I am still with perfectly functional buttons on the HVAC control panel. Well worth the $ and the time to complete the repair.

There is a thread. I’ll look-it’s what inspired me to remove the button silicone bits and try this conductive paint.

After 24 hours of both heated cure and overnight installed back into the vehicle, all the buttons work like new.
