Turn Off the AC Unit
The first thing to do as you figure out how to clean an AC filter is to turn your air conditioner off. Leaving it on while removing and cleaning the filter can cause unfiltered air to circulate through your home.
Turn off the power to your air conditioner. Locate the evaporator coils, which are typically found inside the indoor unit or air handler. Carefully remove the access panel or cover to expose the coils. Use a vacuum cleaner with a soft brush attachment to remove dust and debris from the coils gently.
A rule of thumb is to clean them annually, but environmental factors like dust, allergens, and your AC's usage could warrant a more frequent schedule.

The quick answer is no. The rain itself cannot damage your AC unit. Outdoor units can withstand intense weather, including frequent thunderstorms. However, that doesn't mean it's free of danger.
First, check your filters and coils for dirt and debris that may be impeding airflow. Once you've cleaned the filters and coils, run the air conditioner with just the fan so that the ice accumulation can melt off. If the AC still doesn't blow cold air, it could be that refrigerant levels are too low.
Use a hose to spray down the entire unit, starting on one side and slowly going around it until all of the dirt is hosed off. Don't forget to turn off the power to the unit before you start cleaning, and turn it back on when you're finished.
The short answer: You can get away with running your AC without a filter for a short period of time. However, doing so for longer than 6-8 hours can hurt your system and decrease your home's indoor air quality.
