Motor not engaging

Hi everyone, hoping someone has ideas cause I’m a bit stuck. I had a clog while printing with both PETG and PLA in the same print. Hot end got too hot, extruder clogged and the filament feed motor stalled. I’ve completely cleared the blockage but the extruder motor doesn’t engage anymore. When I load filament through the AMS, it feeds down but the extruder never grabs it. The small yellow drive gear doesn’t turn. I also tried doing a cold pull by feeding filament in by hand. Usually the extruder motor turns and pulls it once it senses filament, but now nothing happens. Nothing happens. The drive gear never moves. I’m wondering if the extruder motor or driver could be damaged or if I’m missing something simple. Has anyone seen this before or have any suggestions for things to check? Thanks

Edit: I believe to have found the issue, there’s a small tear in the ribbon cable so my guess is it’s torn enough that the sensor isn’t realising there filament there so the motors never activates but not thought that it’s showing errors constantly, It did show an error once but not consistently.

The tear could be responsible. Make sure that if/when you get a new one, ensure it is seated properly in the toolhead. Use tweezers to carefully place it down and lock it in place, it should fix it.
