Q: Blower Wire/Power Window Wire Overheating at Ignition Switch on 1993 Dodge D250

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
The Blk/Org Wire coming out of the ignition switch to the fuse box is overheating. Problem was discovered after power windows stopped working and having to jiggle the key to make it work. The wires continue to overheat when held together and operating the windows and blower motor either independently or at the same time. I changed the motor. Used a jump wire from the battery to the Blk/Org wire. Any other suggestions. This has had me baffled for over a year now. Your help would be appreciated.
All wiring connectors in that particular circuit should be replaced. Any wires and connectors which show signs of overheating, loose connections etc. will have high resistance exasperating the condition
