Like the title says, climate control and display no longer working, started happening after installation of aftermarket radio. Checked all fuses and made sure all wires are connected. Aftermarket radio harness only had two clips, but original harness has 3 clips. But after hooking all clips back to stock radio, display and climate control still don't work. Buttons and backlight of mpg display still work but no numbers or controls. Can anyone shed some light on this for me please?
