there is a holding tank in the bottom of the unit, on the front right by the floor is a rubber cap that plugs this tank. water evaporates from there, if the tank gets too full, the power button will flash red and the unit will not turn on. put pan under, pull plug and drain if this happens. if it doesnt happen, don't worry about exhausting the water as its not a problem.

It could be out of refrigerant, but these units don't come with service valves and most AC service companies don't work on them(window units). My experience with this particular brand has not been good

You should start by checking the breakers for the unit ( both the inside and outside unit). Then look for any fuses that may be blown. There is also a force on button somewhere on the side of the indoor unit. After you make sure it has power use that button to try and start it and make sure everything runs. Let me know what you come up with.

need to check the back side of the ac connector where the harness plugs in remove the heater control unit assy and u will see the ac button connector with it still pluged in start the car and turn the ac button on wiggle the ac connector if the light comes on and off it's a loose connection in the harness/connector at the ac button try to jamb a folded over zip tie about 4inches long in between the ac button connector and the plastic frame basicly just make sure that the connector staitionary not wiggling around I had the same problem on my 95 prelude vtec push the ac button sometimes comes on or hitting the dash just got old hope this helps

The button on the plug is a GFI. Ground fault interuppter. Like on your hair dryer. When the unit is running, or has just tripped out, feel the plug and the well receptical. If either feel warm or hot, do not continue to run the A/c unit. Get an electrician to check for a faulty/ worn/improperly wired outlet. The units tripping out for a reason.

the flashing snowflake is it telling you its in % min delay if it doesnt stop flashing within 5min it may be a bad tstat. if it goes solid and the unit is still not working its probably not the stat

tried to remove battery and ac for a little while?

if that doesnt work, remove battery and ac-power.
remove the ram
put ac-power back and try to boot without ram
(do you get a beep/error?)
remove the ac again
insert the ram
insert battery
insert ac
try to boot up again.

if that doesnt work its probably a mainboard error and you need to take the computer to repair.
