Heater core is Bad Sounds like your heater core is the problem. you can bypass the heater core for the summer and be okay if you do not want to spend the money (or need the heater) till winter. There is an inlet and outlet hose for the heater core in the engine compartment on the passanger side. Go to your local auto parts store an purchase the correct size hose splice and simply connect the two hoses together. This will allow coolant to circlute through everything except the heater core.
