Question about 1997 Mercury Villager
Engine temp is normal,double checked for air or low coolant and checked fine.Seems to be intermittant,but mostly just blows cold air.
Your heater core may be getting blocked up, or the thermostat may be stuck open at times. you have a few options here, option 1 and 2 cost about the same, option 1: have the thermostat replaced just so you know its working properly, a 97 will most likely not have a telltale way of knowing if the thermostat is bad or going bad. option 2. have the cooling system flushed at a shop. this will try to clear out and debris in the cooling system that may be blocking passages or the heater core. option 3 is the most expensive. have the heater core replaced, the heater core is what provides heat to the hvac system in the dash. a few other things to check would be vacuum lines/actuator/temperature door on your hvac system.
