Hi everyone... I have a 08 LS600hl.... just one day took it to a place to do cabin filter and at the same time did the Datasystem suspension controller.

When I took the car back, the temperature display had nothing showing.... the main screen still works... and for a couple weeks the button on the control works as well meaning if I press auto, the screen will show auto mode for AC... press the button for outside air it works... heated mirror works but only for a couple weeks.

Now everything is gone. I can still turn on the AC manually by the screen and it's cold and everything.

I have check the gate on the filter and the servo everything works.... Fuse under glove box not blown....

What can possibly be the problem? The unit itself is done?
