Door harness interchangeability

[Nctruckman]

Having some issues with the door wiring harness on the pass front door of my 03 Trac. I understand that the harness for RKE and non RKE are different, but what other years would interchange? Wondering if a 01-03 sport or 99-01 2nd explorer would be plug and play

Curious as to why you think it's the harness? Are there signs of damage to it?

Only ask because generally harnesses don't have many issues. Corrosion would be the biggest culprit.

It's been messed with in the past. I can unsnap the switch panel, lift up on it, then the switch works. The switch has been replaced already too.
