7 Easy Solutions For Jeep Wrangler Heater Not Working Problems
The most important mechanical component of a Jeep Wrangler is its heater. After a prolonged operation, a heating system can be damaged just like any other mechanical component. In the event that you discover that the heating system is malfunctioning, you must address the issue right away.
Here are some solutions which may help you to solve this issue easily.
#1- Change The Damaged Heater Core.
A heating core leakage is among the most typical issues that might affect a vehicle. The Wrangler’s heating core is a little radiator that circulates heated coolant throughout the vehicle. It operates in exactly the same manner as a radiator.
There are a number of signs that will help you figure out whether the heater core needs to be replaced. Some of these indications are:
- Constant loss of engine coolant.
- Sweet odors in the vehicle.
- The cabin has cold air.
- Fog inside the jeep.
- There is no heat.
- Přehřátí motoru.
If you have these problems, you should replace them right away. For a novice, replacing a heater core is a difficult process, but with the correct equipment and enough time, you can replace it. However, we advise you to change this with the assistance of a skilled mechanic.
Replacing the heater core for Jeep Wranglers typically costs approximately $1,000 to $1,200. While materials price will be around $400 to $450, and the labor expenses will vary between $550 and $650.
#2- Clear Blocked Vents.
The principal air passageway in the jeep is through vents. Air cannot effectively travel through the heating vents of the Jeep Wrangler if they are blocked or damaged.
To solve this issue, you have to just clean the vents properly. To clean it, you should use a soft brush. You can also use an air blower. But, if the dirt is clogged badly, you have to take out the whole vents and wash it thoroughly.
This is a simple process, and you can do it without any extensive knowledge. You can fix this issue without spending any money.
#3- Replace Or Repair A Malfunctioning Thermostat.
The thermostat is in charge of controlling the engine’s coolant flow. When the engine gets cold, it remains shut to allow for warming. Besides, it slowly opens when the engine warms up, enabling coolant to enter the radiator. The jeep heater ceased to function correctly whenever it started to fail.
A vehicle’s thermostat could be jammed because of rust or age. It is necessary to keep a few things in mind in order to prevent the car’s thermostat from malfunctioning.
One of these is making sure the coolant is changed on a regular basis and properly to prevent air from getting into the system, which might cause overheating or defective sensors. Here are a few warning signs of thermostat failure.
- Irregular temperature fluctuations.
- Temperatures that are high.
- Leaks of coolant.
- Gasoline usage has increased.
- Unusual sounds and thermal shifts.
- Both heating and cooling.
The easiest way to fix this issue is to replace the malfunctioning thermostat. Although replacing it can appear simple, there are a few delicate elements that a novice technician might damage. So, you should seek the assistance of a skilled professional.
Replacement thermostats for Jeep Wranglers typically cost around $350 to $450, and the labor expenses are expected to range from $60 to $80, while only the component prices can be around $300 to $350.
#4- Clean Out Clogged Air Filters.
The heater air filter in your car prevents debris from entering the heating system and potentially harming vital parts. Air filters should be changed between 10,000 and 15,000 miles, while they might need to be cleaned more often for vehicles operating in congested regions.
A blocked air filter might result from not changing a filthy air filter. If an air filter becomes blocked, it may malfunction, allowing impurities like dirt to enter the heating system. The heater may sustain lasting damage as a result and operate incredibly poorly.
Replacement air filters for Jeep Wranglers typically cost around $60 to $80. The cost of labor is expected to be about $20 and $30, while the cost of equipment is around $30 to $40.
#5- Fill or Change The Heater Coolant
The Jeep heater utilizes coolant, much like every other vehicle, to cool the engine down in hot weather and to circulate heated air through the heat exchanger in cold weather. The coolant normally contains antifreeze and water in a 50:50 ratio.
Although coolant might seem to be a fairly general subject, it is crucial to choose the right coolant formula for a specific Wrangler model and engine. Here are a few coolant categories which you may use in your jeep.
- IAT (technologie anorganických kyselin)
- OAT (technologie organických kyselin)
- HOAT (technologie hybridních organických kyselin)
- Dex-Cool
You should be aware that there are several kinds of coolants and antifreeze. The quality of antifreeze definitely plays an important role, especially if your engine is older. If you use the incorrect coolant, the heater system may stop working.
You have to change the coolant every 30,000 miles to get the best performance. To prevent any unwanted damage, you should change or refill it with an expert mechanic. This may cost you almost $300 to $400.
#6- Replace The Faulty Water Pump.
A water pump plays a crucial function in maintaining the coolant’s circulation, which is necessary to ensure that the engine runs at the right temperature. The engine may overheat if coolant is not circulated, which can cause excessive damage and failure. A malfunctioning water pump may potentially leak more coolant.
Water pumps are intended to endure for at least 100,000 miles, but if yours breaks down, you must change it with a premium piece of original parts. Although there are less costly replacement pumps available on the market, they can only last 30,000 miles.
You should budget somewhere between $350 to $750 for replacing it after taking all of these factors into account.
#7- Replace The Damaged Blend Door Actuator.
A blend door actuator is yet another crucial component of your Jeep’s heater system. The climate control system in your automobile is managed by these components. It appears to be a little plastic container with some inside plastic gears.
Additionally, it performs a crucial duty. The blend door actuator receives signals when you change the dial to modify the airflow or temperature. Also, it regulates ventilation and defrosters.
There are some signs that indicate that the blend door actuator is damaged. And, if you determine the main signs of its damage, you can easily solve the problem. Signs that your blend door actuator is failing.
- Neobvyklé zvuky.
- Unpredictable temperature.
- Sound of thumping or clicking underneath the dashboard.
- The temperature of the climate control outlet is incorrect.
Replace them as soon as possible if they have these issues. If not, there might be more severe harm.
Resetting this component can sometimes solve the problem quickly. However, because the precise calibration process may vary depending on the vehicle model, you should check your repair manual or maintenance database to fulfill the requirements.
You should typically budget around $200 to $500 for the service if you want to have a technician replace the blend door actuator in your vehicle.

I’ve done a lot of research, and I suppose at this point, am looking for confirmation on what I’ve found. Onto my post.
Problém: Yesterday, as far as I know, out of the blue I no longer have heat. To be fair, I really can’t remember the last time I used heat. It’s been a while, at least 2-3 months. However, the last time I needed heat, it worked fine. Currently, the Jeep just blows cold air. Not warm or hot, just cold air.
Řešení problémů: I started with quite a bit of research, and feel like the most logical reason is the drivers side blend door, but we’ll see what the troubleshooting thus far will uncover.
- Checked Coolant Level
- Checked Oil Level and condition
- Jeep warms up properly, and stays at the correct temperature while driving / sitting in traffic
- Passenger side blend actuator works fine — Cold air blows floor, vent, defrost, etc. depending on how I set the controls
- Drivers side blend door actuator does not seem to do anything — It ‘stays’ in the middle no matter where I put the temp on HVAC — poznámky: My Jeep dělá have automatic temperature control, but I have made sure in my tests that neither the blower nor the blend was set to automatic
- I pulled the coolant reservoir and found ‘stuff’ at the bottom — Photo below
- Drained coolant reservoir and tried my best to separate the good coolant and whatever crap was at the bottom — Photo below
- Cleaned out the coolant reservoir. Have not put back together — waiting on getting some distilled water
Photo of the coolant reservoir:
Picture of what was in the reservoir (Jar on the left is a mix of some coolant plus whatever ‘crap’ was at the bottom, one of the right is doing my best to only get coolant, but some of the crap fell in there as well):
Another picture, right after pouring them into jars:
Background on Jeep: My 2013 Jeep Wrangler Unlimited Rubicon 10th Anniversary is a one-owner, it has every option expect it has a manual transmission — so no remote start. It has been serviced at Jeep dealerships due to getting a maintenance package on the Jeep free with purchase. I’ve never added coolant or anything to the system. If it was ever low (not to my knowledge), it would have been the dealer adding coolant and/or water. My Jeep has 21k miles on it, and is out of the 3-year / 36k mile warranty due to time of course.
I have never had issues with heat in the past. It’s always worked, and been boarder-line melt your skin off hot. I don’t really remember any particular time when it’s not gotten that hot if I wanted it that hot, except maybe when it was ridiculously cold (Minus 10-20 degrees, with windchill of -30 or more). I have not had any other issues with the Jeep, outside the oil pressure sensor, which failed earlier this year (Out of pocket repair).
Další kroky: I am kind of torn on what is going on. I feel the issue very well could be casting sand in the coolant, which plugged the heater core. Though I feel this would have happened sooner than 4-years into ownership if this was the case, and I don’t think this problem ‘normally’ starts more or less overnight. It usually has symptoms of heat on only one side, or only Luke-warm heat. The other item that is odd to me, is the drivers side blend door, it doesn’t move. My understanding this one should control hot/cold. It doesn’t do anything, no matter what I do with the temperature switch (Currently its sitting right in the middle of the arm. The third item is that it could be the HVAC control itself.
So, questions to the experts, what is my issue:
- Casting Sand and/or clogged Heater Core
- Drivers-side Blend Actuator
- Ovladač HVAC
- Jiný?
