Heating problem
1 Answer
Check coolant level. Check water pump and radiator for flow. Replace thermostat (you can test old one for operation with a pan of boiling water and thermometer). You can also check heater core flow by removing heater hoses from engine and connecting to a hose. I don't know if yours has a heater valve or not, that would be a valve that opens to let coolant reach the heater core, the valve would be controlled by the climate switch, if it has one, check it too. Good luck.
