I'm having issues with the lights for the icons on my climate control unit. I'm fairly certain the lights aren't burnt out because it has come on before. And because they've light up before I doubt the fuse it out. So I'm wondering if there is somewhere that I can find a wiring diagram of sorts so I can start troubleshooting the wiring. I'm planning on picking up a voltage detector and want to see whether or not it's getting the power it's supposed to.
