Question about 2004 Jeep Grand Cherokee
This is almost definitely a leaking heater, I've made that assumption on the basis that you haven't said the leak occurs during rain.
If you're lucky then a hose has come loose and may just need a hose clip to be tightened, and if unlucky the heater core needs replacing which is a huge job.
Either way, it's imperative that you get this fixed urgently as a leaky heater means that you're losing engine coolant, and if this goes too far then you'll get a truly horrific bill for major engine repairs.
If you're short of money then the heater core can be bypassed; there will be two hoses which supply it and they pass from the engine and through the bulkhead. They can usually be disconnected at the bulkhead on the engine side and the hoses from the engine can then be joined using a short length of metal tubing and two hose clips.
Whatever you do, check the engine coolant level immediately and top it up as necessary using the correct mix of coolant/antifreeze and water.
