The top button on the DIC does not work, replaced the buttons and still the same. Sometimes intermittently it will work, especially after a car wash the display will change and I can cycle it a couple times.

My thoughts were a bad ground?

Wish I knew.

There is a wiring junction point under the dash, center, near the floor, may be in there.

But would it get wet.

Any wet areas under the hood after a wash?

There is also a ground point under the drivers side sill plate.
