Hey guys, i'm screwed now, I did the tricks for the Heater control and after reinstall all stuff I got some problem. I double check two times all connection and still have some issues, First I don't have any display, it is just dark, nothing at all. and the second is, all my control for A/C, defrost, etc doesn't work but i can control the speed of fan. I'm also able to cds but not load one and can't play music I don't have the beep when you press on a button.
All light on the radio are working fine. I just don't know what happen. Hope that I didn't break a wire, but it is impossible I took my time to do this. need help


Thank you
