1UZLS4001990

No, it's been removed years ago.

I have a 1990 LS400 (with CD changer) which I swapped in a double din radio system a few weeks ago, the radio works fine apart from the fact that the climate control has a mind of its own. I'm unable to turn it off or change any of the settings, it just keeps blowing cold air on medium regardless of what I do. I don't know if it has to do with the fact that I removed the negative battery terminal during the swap or because it doesn't like being unplugged. I want to enjoy my radio without the A/C constantly blowing on me, it doesn't help if I close the vents which makes it even harder to hear the radio.
