Default Help get furnace running, basement flooded

So, I get home from work last night to 18" of water in my basement. The sump pump didn't kick on (the float switch stuck) and it had been raining all day long. I waded through the very cold water, jiggled the float switch, and it kicked on. 3 hours later, I was down there inspecting things and trying to get the furnace running again. Part of the control board had been submerged. I'm not sure exactly how high the water got, perhaps some of the blower motor was submerged as well.

Thankfully, its not super cold out right now so I have some time to get it running.

Anyway, I'd very much appreciate some help getting this thing running again. Here is what happens, it almost works... The exhaust fan kicks on, the igniter powers up, the gas valve kicks on and it fires up. Everything is good until this point. Then I hear the relay click for the main blower fan to kick on and nothing happens. So, I assume that something in the blower motor circuit is bad. In my mind that means a bad motor, bad capacitor, or the relay that I hear click is actually not working correctly. I haven't been able to test any of the components yet. Testing the relay to make sure it is sending power to the motor will be the next step pending any additional info you guys can provide.

Here are a few pics. I think the water came up a bit beyond the bottom of the control board, but not real far up. Unfortunately, the bottom of the control board is where all the relays are.
