    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?

    Abc warehouse. They don't know what it is. They said its my fault because I had an aaftermarket converter for the stock radio to have a subwoofer running off it. Some thing the previous owner had installed. But it all worked before they touched it. Trying to figure it out instead of shelling out hundreds of dollars at a shop to have it fixed. I'm thinking maybe they accidentally touched some wires and shorted them out but I'm convinced it's a different aftermarket clip I need on there. But no one knows of any clips that support my third one. I'll try to post some pictures tomorrow

    time to pull the head unit and it's wiring. Check for any cut, nicked or tested wiring that was done and tape it up. Check the fuses and then see if it works. If you get it working w/o the radio, then you can reinstall it and see what is done and how it was done. When you get it in..you should have a good understanding of what is wrong.
    I drink..so consider that when reading my posts.
