heater is only blowing cool air. Thermostat changed, after thermostat changed, still blowing cool air. Now when defroster turned on A/C ingages. After running for a while checked coolant level and topped up. Took for a short drive to test and heater worked fine. Turned on A/C to check, but it did not get cold. Turned heater back on and was blowing cool again.
