Q: Heater not working

The heater in my vehicle doesn't work.

Hello. If the heater does not work I always check the coolant level first. If the coolant level for the engine is low then not much coolant will enter the heater core which results in little to no heat. If there is coolant and if the engine temperature is fine, then it may have a problem with the blend door under the dash. This is not too common on this vehicle. Most of the time it is a coolant issue. It can also be a clogged heater core. I check the temperature of the heater hoses when the engine is warm to see if they are hot. If there are not and the coolant is full and the heater core may be clogged. If you are going to have it fixed, consider YourMechanic, as a certified mechanic can come to your home or office to diagnose your heater and make necessary repairs.
