Window AC Unit Troubles?

We had a storm here 2 nights ago. Yesterday, the electricity shut off for about 1.5 hours. Later I noticed my window ac unit was having trouble. It works, and the air feels cold like air conditioner, but won't let me control the speed, coolness, or use "fan only"-- I've unplugged and retried. My suspicion is that it's holding too much water from the storm, though it's not its first storm. It sometimes makes a cracking sounds and goes up and down in power at its own will, but its not doing much.

Knowing nothing about an ac unit, I need to know if its broken or if I keep it running will take care of the problem on its own by using the water it seems to be holding (thats my only guess). I never turn the unit directly to off, I always run the fan first to rid the excess water so it won't smell.

Thanks!
