My Tarus is acting up again. Don't want to warm up takes it forever for heater to get warm never gets hot. Driving down the road it will cool down at times til it is blowing cold air. Running at Interstate speeds it will stay barely warm. Thermostat junk?? Always just stuck on me when they went bad and cause thing to overheat. I guess this is better if it has to act up but a heater would be nice......
