My van sometimes will not heat at all for over 15 miles. The temperature gauge shows correct temp. It switches from defrost to ac and all that but no heat.All of a sudden it starts heating correctly. Can you help Please
Hey there
See if you can help narrow things down for me. Feel the heater hoses like I suggest in the article, both should be hot to the touch. If one hose is hot and the other is warm/cold you probably have a blockage in the heater core itself.
If neither hose is hot, you probably have a poor circulation problem like a restricted radiator or faulty thermostat, or just low coolant in the radiator. If both heater hoses are hot, you probably have a control problem inside the dashboard somewhere.
If you suspect a blockage in the heater core and want to try and “flush” it yourself first before getting your mechanic to replace it watch this short video for tips.
