Unhappy Heat pump blower/motor/relay questions

My fiance and I are avid DO IT YOURSELFERS. We're young and just bought our first house, which was somewhat of a fixer upper. We're out in the country and have found that we can usually fix a problem ourselves for less then a professional's trip charge to come out here. I usually try to do internet research until I can find a solution...but this one has really stumped us!

This is a 2001 double wide home with a 2001 Intertherm/nordyne heat pump. We used the heat pump this winter and seemed fine. This summer when we began using the AC, we noticed a wet spot in front of the closet where the inside unit is housed. We planned to get a "snake" to clear the drain-but the next day the fan stopped turning.

(outside unit comes on and is working fine, we can hear refrigerant swishing around inside and then the coils freeze up.) Could it be possible that the drain was clogged and the drip pan filled up and dripped on the fan and motor? We took the "squirrel cage" out and cleaned all of the blades in fan. We plugged the motor itself to the wires on inside unit and it didnt spin. I think I need to check the relay/fuse next and dont know how to access it. could you explain how?

If the Relay isnt bad-do I replace the motor?? Does it sound like we are going in the right direction?

With the unit on give the indoor fan a little push and see if it will start. If it starts replace the capacitor "looks like a little tin can". If it wont move replace the motor and capacitor. If it just free spins you need to use a meter and see if it's getting voltage. Don't let the outdoor unit run without the indoor fan.

Like Matt said dont run the AC with out the blower fan on. Have to have a meter to tell if you get voltage to it.Also try and jump R to G on the tstat ,you should hear a relay close in the unit that should send power to the fan to turn it on for cool see if it works.
