Chrysler Pacifica climate control reset instructions

Advanced climate control systems in vehicles today are prone to electrical problems. Symptoms include feeling hot air on the driver’s side of the car while cold air is blowing out of the passenger’s side (or the reverse). 
If this sounds like your situation, don’t fret just yet—try resetting the HVAC system. The process is simple enough that most car owners find they can do it themselves without paying a professional. 
Here are the steps:
Step 1: Turn the key to the on position. You can ignore whatever temperature the AC display shows at this point. Move on to the next step.
Step 2: Turn on the auto control on the A/C. The Pacifica’s A/C system will then attempt to control the cabin’s temperature. The air may blow cold—or hot. If you find the cabin getting too warm, be sure to roll down the windows.
Step 3: Turn off your Pacifica, leaving the A/C controls on auto. You want the A/C to turn on automatically the next time you turn on the engine.
Step 4: Locate the fuse box. Consult your owner’s manual to find the fuse box. In many GM vehicles, the fuse box is located under the hood on the driver’s side, and the lid reads “Fuse and Relay box.”  
Step 5: Locate and take out the HVAC battery fuse. (Look underneath the fuse box lid, where you should find markings that indicate which fuse is which.) If the HVAC battery fuse looks blown, replace the fuse. If it looks ok, wait for about a minute or so and reinstall it.
Step 6: Start the car—but don’t touch anything! Once the fuse is reinstalled, get back in the Pacifica and start it up. Let the car run for a minute or two without touching any buttons.
When you follow these steps, your Pacifica’s climate control system should reset itself. If the air conditioning still isn’t working, it’s time to do some further troubleshooting. 

Other reasons your Chrysler Pacifica A/C isn’t working

Hopefully, you’ll discover that the climate control reset resolved the problems with your Pacifica. However, if the reset approach doesn’t work, there may be a more complex issue. Take a look at these potential problems below, roughly listed in order of severity. 

Blown HVAC fuse

Inspect the HVAC fuse when you take it out to reset the AC. If you see any corrosion or other visible signs of damage, you may need to replace the fuse with a new one before the HVAC system can come online. 

Dirty cabin air filter 

If your filter is clogged with pollen or dirt, this can reduce the airflow in the cabin and put a real strain on your A/C system. While there is no standard recommendation for changing a cabin filter, most vehicle experts recommend that you do so every 10,000 to 20,000 miles. 
If you typically drive on dry, dusty roads, you will want to change your filter more often. So, be sure to inspect your cabin filter to see if it is dirty.

or replace it yourself.

Dirty, clogged, or leaking condenser

The condenser part of your A/C system acts as a heat exchanger, cooling down the refrigerant and condensing it into a liquid state. If your condenser is dirty or leaking refrigerant, it won’t operate properly, and you’ll notice a decrease in the AC’s production of cold air. 
As you might imagine, cleaning a condenser is a bit easier than fixing a leak. A
leak detector
can diagnose the situation—and sometimes all you need to do is use a
sealer product
to seal up the leak.

A/C refrigerant (freon) leak

If your Chrysler Pacifica has been leaking refrigerant (freon) for a while, even after you fix the leak you may not notice much of a change. That is because you’ve lost too much of the freon. 
Your mechanic may recommend an A/C recharge, which will fill the system with the freon it needs. 

Bad A/C compressor relay

The relay is what sends power to the compressor, so if your A/C compressor relay is bad, the compressor won’t turn on. Your mechanic should be able to diagnose a bad compressor relay and perform an
AC compressor relay replacement
.

Bad compressor 

This is the most costly of potential HVAC problems. Your Pacifica’s compressor is at the heart of its A/C system—and it can go bad over time. 
Unfortunately, if you do need a new A/C compressor, expect to pay $1,000 or more for the repair.

How to diagnose a Chrysler Pacifica climate control malfunction

The issues mentioned above are not an exhaustive list of possible climate control problems in your Pacifica. From a loose connector to corroded wiring, you may have an issue that is interfering with the way your A/C is working. 
If you have an OBD scanner, use that to
read it to get a trouble code
, which can help you narrow down the cause of the problem. 
If a simple reset or fuse replacement doesn’t do the job—and you’re not comfortable with an OBD scanner—bring your Pacifica to a professional mechanic, who should be able to diagnose the problem. 
It may wind up being costly, but having a comfortable cabin temperature is not just a luxury you can live without. In hot weather, having a vehicle with working A/C is especially important for the elderly and children, as they can quickly become dehydrated in a hot car.

How to keep Chrysler Pacifica insurance costs low

The annual average repair costs for a Pacifica are around $480, according to RepairPal. That means that the typical Pacifica owner probably will wind up spending well over $500 annually when it comes to repairs and maintenance combined. 
With these costs in mind, it makes sense to find ways to save money, beginning with your car insurance.
