Keyless Entry Finicky - Driver side

2014 Civic Si. Driver-side keyless entry / touch-sensitive handle area doesn't work most of the time.

• I have to twist / flex the door handle considerably for it to recognize that I am touching it.
• At first, when it was working more or less, it would even unlock when I got close to the door, without touching it, especially when wet.
• Clearly, there is a wiring/connector short/open problem.
• Passenger side works like new.

Has anyone else experienced this and fixed it? Needed a new door handle? Needed to just open up the door and play with wires / connectors?

Thank you.
