My car is not putting out heat, it is 19 degrees outside and the temperature gauge is going all the way to the top when I'm driving so I have to keep stopping on the side of the road to let it cool down. I am going on a 12 hour drive and it is making it very difficult
My car has 140430 miles.
My car has an automatic transmission.
Hi there. Check the coolant temperature sensor and see if it has a loose connection on the wiring harness. This will cause the gauge to fluctuate up and down as the engine is running. For the heater not working, check the heater control valve on the heater hoses and see if its working. If the hoses are cooler on the cab side and the engine side hoses are hot, then the valve is not working and it should be replaced. If you need further assistance with your heater not working, then seek out a professional, such as one from Your Mechanic, to help you.
