So, when I press the front defroster button, the light on the button never lights up. I took my 2013 Land Cruiser to the dealer and they diagnosed it as being a bad A/C amplifier (what the eff is an A/C amplifier?). They ordered the part, put it in today, and said that while the computer is now getting a signal from the A/C amplifier, the defroster still isn't working. They are now suspecting a wiring problem.
This is not good.
