RV Repair: RV air conditioner problem, rv air, sequence of events

Question
The unit doesn't blow out any air one moment then all of a sudden it begins blowing again.  No rhyme or reason or time frame. what could cause this?

Answer
Hi Chris:

I need a little more information, then I will do my best to assist you. I need the brand and model number, as there are lots of various ones. Then, I need a detailed sequence of events. You said the blower did not work, then all of a sudden it came on, how long did it continue to blow. When the fan started blowing was the air coming out, cold? When you shut it off, did it restart by itself when turned on, or did you have to wait a few minutes?
