    Your thermostat is probably not the problem, unless you have an overheating problem as well. You could have a bad heater control valve since your air conditioning is working fine.

    Proper diagnostics should be administered first, but if it is the heater control valve, the cost: parts, labor, coolant, tax is about $238.
    We are located in South Sacramento. Off 99/Fruitridge Rd at 5681 Franklin Blvd, Ste C.
