Ford F150 Heater Not Working? (SOLVED!)

|

If your Ford F-150’s heater isn’t working, there are a few things you can do to try to fix the problem. In this blog post, we’ll go over some of the most common reasons why your Ford F-150’s heater might not be working and what you can do to try to fix it.

1. The Most Common Reason For A Heater Not Working Is That The Coolant Level Is Low.

If your coolant level is low, it’s likely that your heater core is not getting enough coolant. To check your coolant level, open the hood and locate the coolant reservoir. The coolant level should be at or above the “full” line. If it’s not, add coolant until it reaches the “full” line.

2. Another Common Reason For A Heater Not Working Is A Blown Fuse.

If your heater is not working, check the fuse box to see if a fuse has blown. The fuse box is usually located under the hood, but it can also be located in the interior of the vehicle. If you see a blown fuse, replace it with a new fuse of the same amperage.

3. The Third Most Common Reason For A Heater Not Working Is A Faulty Heater Core.

If your coolant level is full and the fuse is not blown, the problem may be a faulty heater core. A faulty heater core can leak coolant, which can cause the engine to overheat. If you think your heater core may be leaking, take your vehicle to a mechanic to have it checked out.

4. Another Possibility Is That The Blower Motor Is Not Working.

The blower motor is responsible for blowing air through the heater core. If the blower motor is not working, the air will not be blown through the heater core and you will not feel any heat. To test the blower motor, turn on the engine and the heater. Then, put your hand in front of the vents. If you feel air coming out of the vents, the blower motor is working. If you do not feel any air coming out of the vents, the blower motor is not working and will need to be replaced.

5. The Final Possibility Is That Thermostat Is Not Working.

The thermostat is responsible for regulating the temperature of the coolant. If the thermostat is not working, the coolant will not be heated to the correct temperature and you will not feel any heat. To test the thermostat, put a thermometer in the coolant and start the engine. The temperature of the coolant should rise to the correct temperature. If it does not, the thermostat is not working and will need to be replaced.
