Looking for part, need help?!?
 

So recently my AC switch broke and I was not able to turn on the AC. I just keep spinning.

I got a new control switch and when I installed it I noticed the wiring harness that connects to the switch looked pretty melted. I was wondering anyone had any ideas on either:

1) what is the part number is for this
2) how easily would it be to replace it.

See attachment.. thanks ahead of time.

Thanks,
Eddy
