Hey guys,

I come from the heavy equipment world which I know is different. The electrical systems, wiring harness, and ECM's all operate on a similar theory. Would that ECM in the passenger kick panel be waterproof, and would the electrical connection be waterproof as well?

If not, maybe that is where your Christmas tree dash is coming from (water allowing unwanted voltage to jump from terminal to terminal). I would imagine the fuse panel would have protected circuits from direct shorts. I would guess the harness is fine, but needs to have the terminals dried out. Worst case scenario, maybe that ECM in the lower kick panel would need replaced assuming you can dry out the harness okay?

I just don't see how this would create electrical gremlins for the life of the vehicle. When diagnosing electronics, the issue can only come from 3 things. The sensor, wiring, or ECM. Software issue's shouldn't apply to your situation.

I know this is all armchair diagnostics, I'm just spitballin' here and sharing my thoughts.
