Thanks. Good pics. Wiring intact. So next step is new cam.Check the wiring in the trunk. There's a plug that may work loose.

Nope. But good suggestion. I'll look up the pin outs and check for voltage. What would block the voltage from getting there. Fuse is good. Screen pops up. Backup lights comeon. Is there a switch/relay that turns on the cam somewhere ??Is it getting voltage?
Ok I'll do that soon. My "nope" from previous post meant I haven't checked for voltage yet. Still looking for proper pinout/wireing for the camera plug. Can't find any specific to a CTS. Found two other caddy cameras but the pin outs were different it seemed. I'll figure it out soon enough.Check the pin connection, if it has voltage than check the camara plug. If no voltage there, probe the meter lead into the camera wire itself to check for voltage. Maybe the camara plug is corroded.
Also make sure it's getting a good ground.
Thanks what I'm leaning towards now. I'll know tomorrow once I check for voltage. Going to swap cams anyway. I've heard the replacement cams are better than the original.You can probe all the pins and see if voltage appears on anyone of them in the correct mode.
If the backup lights work and voltage appears, then you might have a video break/bad switch in the display.
Got my car back yesterday from the dealer. I gave up trcking the issue down. Turns out it was a combination of the harness and the camera. They replaced both. The difference from the original and the new camera is like watching 720p and 4k. The color and sharpness is drastically different.
According to my bill the part number was 23171840. Not sure if that is an upgrade or an improved version of the original cam. But it's definitely a much better cam. The part number you listed is the wagon cam.Did they provide you with a part number for the camera they used? I am wondering if P/N 22922659 is still the correct upgrade.
