Good place to start is up on the roof. Look way under the unit (hard to see some times) along the bottom, between where the gasket sits on the roof and metal bottom of unit. Should see small round or similar sticking down from unit. There will be a hole in the side of them. Poke around with a wire or something to open them up. If you don't see water/condensation running across your roof from unit when it's operating, (usually in 2 directions, 1 each side of unit) then yup, there plugged.

Yes.

a. Remove the cover of the thermostat.
b. Connect the RED wire from the air conditioner
to the “RC” terminal on the thermostat.
c. Connect the “YELLOW” wire from the air conditioner
to the “Y” terminal on the thermostat.
d. Connect the “BLUE” wire from the air conditioner
to the “H” terminal on the thermostat.
e. Connect the “ORANGE” wire from the air conditioner
to the “G” terminal on the thermostat.
f. Push the thermostat wires into hole in wall and
fill excess hole with insulation.
g. Mount thermostat base to the wall with screws
provided.
h. Check all thermostat wires on base to ensure
they are completely clear of the bimetal coil of
the thermostat. Adjust if necessary.
i. Replace thermostat cover.
If nothing operates on the air conditioner, remove the
return air grille assembly and verify the red, orange, yellow
and blue wires are properly connected (red-to-red,
orange-to-orange, etc.).
Next, disconnect the red wires and check for 12 volt
DC between the red wire from roof section and the orange
or blue wire from roof section. If no voltage received,
refer to Section F2. If voltage is received, the
problem lies with the thermostat or thermostat wires.
Next, disconnect all 4 wires (red, orange, yellow and
blue) from the thermostat. With the thermostat set on
COOL mode, FAN mode set on AUTO and HIGH, and
temperature selector set lower than the room temperature. Check for continuity between terminal RC (red wire)
and terminal G (orange wire); and RC (red wire) and
terminal H (blue wire). If continuity is achieved on each,
proceed with the next step.
Set fan switch to LOW. Continuity should NOT be present
between terminal RC and Terminal H, but present between
the other terminals (Y & G) and terminal RC.
If all of the previous checks are good, the thermostat is
good, do not replace it. If any one of the previous checks
are not correct, replace the thermostat.

There are several models out there. Here are a couple of manuals with wiring diagrams that I believe will help you regardless of the model number. However, if they are unable to help you, let me know the exact model number and we'll search for the wiring diagram. :-)
