HELP!! Coolant Leak

I have a 2009 Dodge Caliber SXT 2.0L I have a driver side coolant leak on the inside of the car. Can any one tell me what I need to do to fix it and fix it fast?

My guess is heater core is leaking. The only quick fix is to bypass the heater core. You won't have any heat then. Look at the firewall under the hood. You'll see two hoses that run into the firewall going to your core. You pull them off the firewall and join them together using like a piece of 1/2" copper & some clamps. Whatever the inside diameter of the hoses are.
