Most likely a vacuum leak. First check if the bigger ac line below/behind the drivers side wheel well is cold and the small one is hot. If that's ok its probably got a vacuum leak. Pulling the side panels will allow you to see the vac hose that operates the door that switches air flow from the heater to the ac. there is a connector on it. Pull the connector apart and suck on the hose to the actuator. If the actuator moves the door you have a vacuum leak somewhere. Good luck finding it. I havent found mine. Sucked on the hose w/ a Golf tee in my mouth and pushed into hose w/ my tongue. Kept door in ac position, but my evaporator isn't getting cold. One more thing to fix.

You can unplug the blower motor and run a jumper wire to test the blower motor. If it is grounded through the plug you'll have to run a ground wire to it also. Blower Motor tested good. The Problem was the Blower Motor Controller which was located on the firewall just below the Heater Hoses. Thanks for responses to question.
