Does anyone know if there is a plug in the engine bay or ground wire the directly effects the climate control system from working?

 

Is the climate control working despite the lack of display? Is the radio working fine?

 

it might be just the plug that goes into the back of the display.

 

The radio works fine and illuminated back light for the ac controls work just the display and the controls them selves dont work

 

Is it still the stock radio, or aftermarket?

 

I got a jdm double din and it works great

 

It's really, really are, but the JDM climate controls may have gone out. Do you have the old parts to connect up the old radio to eliminate the JDM climate controls as the problem? You do need the full radio installed, not just plugging in the climate portion of the old radio trim.

 

No I dont have the oem controls my car came with the double din setup. But maybe this weekend when I have the time and if I could get some wiring diagrams ill try trace back the problem. I read on the other threads that the climate controls and radio will work just the lights dont work or something like that?
