My part Cooling Fan wires melted after accidentally sandwiched between heeatend and silicon sheathing

Hello everyone, first time around here. I was printing all happy and dandy after changing my nozzle and i realized that all of a sudden the bridging and cooling capabilities of my ender 3 v3 se printer got bad all of a sudden.

I was teying to find why it wouldn’t bridge properly so, i tried orca calibrations to no avail. I decided that this isnt software, this is hardware and took the extruder off for a check.

I tried resoldering and placing it back but it seems like nothing is happening after plugging it in and turning the fan to 255 in the control panel. Could my PCB be damaged? Or is it the fan?

I dont have a multimeter as of now so i cant really check it. Is there anyone who can help me with this? Thanks!
