Unfortunately this is pretty common on vehicles that have switches and other components in the center console like this. 9 times out of 10 it is just the switch but the only way to know is to pull the switches out and inspect the wiring connectors and replace the switches. Assuming this was not just water, it most likely has gotten on the switch contacts and it actually prevents the switch contacts from making good contact. Soda is the worst because it leaves a residue that does not evaporate.
Let us know what you find but I don't see any other solution then to remove the switches.
