collant leaking into the passenger compartment. and windows fogging up
leak on 2002 Land Rover Freelander
It sounds like the heater core has failed. Check the engine coolant level and top it up. Have the cooling system pressurized, a repair shop use a tool that looks like a bicycle pump with a pressure gauge on it. The cooling system generates about 15psi pressure when its hot, this tool simulates that pressure so the leak can be located but it is most likely the heater core has failed.
