i have question about radio and climate control system in Lexus cars in general. If "some of the button" don't light up on your climate control or your head unit, do you have to replace the entire unit, or do you think it's just the wiring?

 

should be just the light bulb.

 

so the dealrship won't charge arm and leg, if it's just a light bulb right?

 

They might get you for labor. They might also say that we cannot open up the units, and require you replace the entire headunit.
