There are many possible causes for why your rear heat isnt working, including loose or damaged wiring, a broken fan motor, or clogged air filters. In order to get to the bottom of your rear heat issue, it is important to check each of these items in turn. This guide will walk you through the diagnostic process step-by-step and hopefully get your Durangos rear heating system up and running again in no time.

Overview

The Dodge Durango is a mid-size SUV that has been around since 1998. It is a popular vehicle and has been hailed for its dependability, power, and comfort. One of the features that makes the Durango so comfortable is the rear heat system. This system utilizes air vents to provide warmth to passengers sitting in the rear of the vehicle. Unfortunately, there are times when the rear heat may not be working properly. In this article, we will discuss what can cause this issue and how to fix it.

Common Causes

The most common cause of a malfunctioning rear heat system on a Dodge Durango is a faulty blower motor. The blower motor is responsible for circulating air throughout the cabin of the vehicle. If it is not working properly, then it can cause an inadequate amount of air to reach the rear vents which can lead to poor heat distribution in that area of the vehicle.

Another potential cause could be an obstruction blocking airflow to or from the rear vents. This could be anything from leaves or dirt that has accumulated around them, or even something as simple as a piece of tape blocking one of them off.

Troubleshooting

The first step in troubleshooting this issue should be to inspect the blower motor and make sure it is functioning properly. You can do this by turning on your vehicle’s climate control system and setting it to recirculate mode with both fan speed and temperature set to maximum values. If you do not hear any noise from your blower motor at this point, then you should replace it as soon as possible in order to get your rear heat working again.

If you hear noise from your blower motor but still do not feel any warm air coming from your rear vents, then you should check for any obstructions blocking airflow both inside and outside of your vehicle’s cabin. Make sure all vents are clear of debris and that nothing is blocking them off from air flow coming from either inside or outside your car. Once you have done this, turn on your climate control system once again and see if warm air starts flowing through all vents including those in the rear area of your car’s interior cabin space.

Conclusion

In conclusion, if you are having issues with your Dodge Durango’s rear heat not working properly then there are several things that could be causing it such as a faulty blower motor or an obstruction blocking airflow either inside or outside of your car’s cabin space near its rear vents. The best way to diagnose this problem would be to inspect both these components before attempting any other repairs or replacements on other parts related to the heating system in your vehicle.

Common Problems

The rear heat not working on a Dodge Durango is a common problem. The most likely cause is the blower motor resistor. This component is responsible for controlling the speed of the fan, and if it fails, then the blower will not work correctly. Other causes could include a faulty fuse, an open or shorted blower motor, or a bad wiring connection.

Diagnosing the Problem

The first step in diagnosing the issue is to check the fuse box and find out if any of the fuses related to the rear heat are blown. If they are, then they will need to be replaced. If they are not blown, then you can proceed to testing the blower motor resistor and wiring connections.

To test the blower motor resistor, you will need to locate it and disconnect it from its wire harness. Once disconnected, use an ohmmeter to check for continuity between each of its terminals. If there is no continuity present, then that indicates that it has failed and needs to be replaced.

Next, you should inspect all of the wiring connections for signs of corrosion or other damage. If any of them look bad then they will need to be replaced as well.

Replacing Parts

If any parts need to be replaced due to their failure, then you should do so as soon as possible. It is important that all new parts be properly installed and connected in order for them to function properly and avoid further issues down the road.

When replacing the blower motor resistor and wiring connections, you should make sure that each one is securely fastened into place and that all electrical connections are properly made before proceeding with installation of other components. This helps ensure that everything functions as intended once completed.

Conclusion

When dealing with rear heat not working on a Dodge Durango, it is important that all potential causes are investigated thoroughly in order to determine what needs to be done in order to fix it. This includes checking fuses, testing components such as blower motor resistors and inspecting wiring connections for signs of damage or corrosion. Once any faulty parts have been identified, they must be replaced with new ones in order for them to function correctly once again.

FAQ & Answers

Q: What are the possible causes for a Dodge Durango rear heat not working?
A: Possible causes for a Dodge Durango rear heat not working include a faulty or broken blend door, a malfunctioning blower motor, or a clogged heater core.

Q: What should I do if my Dodge Durango rear heat is not working?
A: If your Dodge Durango rear heat is not working, you should first check the blend door to make sure it is in good condition and functioning properly. You should also inspect the blower motor and check to see if it is running correctly. If all else fails, you may need to have your heater core flushed and checked for any blockages.

Q: How can I tell if my Dodge Durango blend door is broken?
A: You can tell if your Dodge Durango blend door is broken by inspecting the actuator that controls it. If the actuator has become disconnected or damaged, it could be the cause of the problem. You can also check to see if the door itself has become stuck or jammed in place, which could also prevent it from functioning properly.

Q: How do I replace my Dodge Durango blower motor?
A: Replacing your Dodge Durango blower motor requires removing the old one and installing a new one in its place. First, remove any screws or bolts that hold the old blower assembly in place and then carefully remove it from the dashboard. Next, install the new blower assembly by following all of the instructions included with it. Once installed, reconnect all wiring and test to make sure everything works properly.

Q: How can I flush my heater core on my Dodge Durango?
A: Flushing your heater core on your Dodge Durango requires draining out any fluid that may be inside of it and then flushing out debris with a garden hose. First, locate your heater core valve under your hood and drain out any fluid present inside of it using an appropriate container or container tube. Once drained, attach a garden hose to one end of the valve and use water pressure to flush out any debris inside of it until all clogs are removed. Once completed, replace valve cap and refill with coolant according to manufacturer specifications before testing again for proper functionality.

In conclusion, the Dodge Durango Rear Heat Not Working issue is likely caused by a faulty thermostat, a disconnected hose or a blocked heater core. If the issue persists after checking these components, it may be necessary to replace the blower motor or the entire heating system. It is also important to check for any other problems that may be causing this issue before attempting any repairs.
