If you look under the hood. Youll see the a/c case. Under the evaporater there is a drain there is little hose with a elbow. You need to remove it and probe the hole to clear the blockage. Then youll see all the water coming out. If you cant get it from the top youll have to put it on a lift and clear it from the bottom. If you see coolant coming out you will have to replace the heater core.
