Ok, The sound went away when before i tried the water test. So I went ahead and did it anyways and it didnt come back until today on my way between jobs. THis time it wasn't very consistent. I turned the radio OFF (took face plate off) and no HVAC was on. I did not try wd-40 yet.
Could the fuel pump make that kind of noise?
Its not loud like a cricket but its the steady chirp like sound they make.

Any other tactics to try? I'll try the wd-40 tonight after work.
