The heater core or connecting hose is broken.
Head gasket could be bad
Probably a blown or leaking head gasket.
Antifreeze? Water pump?
If you are sure it is water and not coolant, then the A/C Condenser drain line is stopped up. You will find it near the firewall on the passenger side. Look for a tube under the Jeep. If it is coolant, which will taste sweet, your heater core is leaking and must be replaced.
A smell inside is usually a bad evaporator coil.
i believe you can put the antifreeze anywhere in a jeep
That is most likely antifreeze. Have the cooling system checked for a leak.
You will need to replasce the heater core.
A 1997 Jeep uses the regular green antifreeze.
Probably brake fluid, your caliper seal may have gone bad
Heater core
A 2008 Jeep uses red, five year antifreeze.
