I mentioned this morning when drove to work that my High Beam has reverse operation. Basically when I push the leaver forward, the High Beam indicator is ON, but the lights are actually in Low Beam. When I pull the leaver backwards, the indicator goes OFF, but High Beam is activated now in headlights.
Basically in Low Beam control position the lights are in High Beam operation and in opposite in High Beam control and light ON the headlights are in Low Beam operation.

What can be wrong?

I recently changed the bulb in the dash backlighting. Could it be bad connection in one of the gauge cluster plugs? As of the High Beam indicator and the lever position, they are aligned, just the headlights operated in reverse mode.

I washed the engine bay yesterday, but I used garden hose with low shower settings and dried the engine thoroughly before starting.

Need some help finding the mystery....
