You’ll need to remove and replace the HVAC/ECAS fuse to reset the climate control in your GMC Yukon if the air conditioning system has stopped working or is blowing hot air out. 
The GMC Yukon is a seven-passenger SUV built for comfort with plenty of third-row leg room and equipped with tri-zone automatic climate control. But when that luxurious cooling system stops working and blows hot air out of the vents, the spacious cabin is anything but comfortable for you and your seven passengers.

GMC Yukon climate control reset instructions

While there are plenty of possible reasons the automatic climate control isn’t working in your GMC Yukon, the most common are electrical issues. If you noticed hot air blowing from your air vents, resetting the HVAC system is the easiest way to fix the problem.
If you have five minutes to spare, you can reset your HVAC at home by following these steps:
Step 1: Turn off your car. You don’t want to handle the fuse box while your car is running–that’s a recipe for electrocution.
Step 2: Locate the fuse box. The fuse box will either be under the hood on the driver’s side of the vehicle or in the trunk. If you aren’t sure, you can check your owner’s manual for the exact location of the fuse box.
Step 3: Find and remove the HVAC fuse. If the fuses aren’t labeled, there will be a fuse map inside the lid of the fuse box. Look for the fuse that says “climate control” or another phrase like that. 
Step 4: Pull out the fuse, wait 10 seconds, and reinstall it. You’ll want to
remove the fuse carefully
and handle it gently before reconnecting it. This is also a good time to inspect the fuse to see if it has blown.
Step 5: Start the car but don’t touch anything for a minute! After you’ve reinstalled the fuse, restart your Yukon and sit without touching anything (especially the A/C buttons!) for about a minute. 
Your GMC Yukon’s climate control system should reset itself once you complete these steps. If the air conditioning still isn’t working properly, you’ll need to do some troubleshooting.

Other reasons your 2004 Chevy Tahoe A/C isn’t working

Resetting the climate control system will fix most electrical system problems causing your A/C to malfunction but not all. You may also be dealing with a different problem altogether if the HVAC reset failed. Here are some other reasons your Yukon’s A/C is malfunctioning.   

Dirty air cabin filter

The air cabin filter is an important part of your ventilation system and if it’s dirty you’ll notice reduced airflow. It’s recommended you
change your air cabin filter
every 10,000 miles to keep this problem at bay.

Clogged condenser

Your air conditioning condenser and main engine radiator are next to each other in the front of the Yukon and are prone to grim build-up. Air won’t flow through a clogged condenser causing poor cooling. Simply cleaning your condenser will fix this problem.

Faulty blend door actuator

If you hear a clicking sound coming from under the dashboard whenever you turn on the A/C or adjust the temperature, you’re dealing with a faulty blend door actuator. The blend door actuator is an important component that controls the vents which control the airflow into the interior of your vehicle.
To get your climate control functioning properly, you’ll need to head to a mechanic to replace the bad blend actuator.

A/C compressor failure

The
A/C compressor
is a crucial part of your HVAC system, converting the coolant into a liquid that keeps your Yukon cool. If your compressor fails it will need to be swapped out for a new one. 

Refrigerant fluid leak

Leaking refrigerant fluid is one of the most common causes of a faulty Yukon air conditioning system. When you refill the refrigerant fluid and the levels drop dramatically then you have a leak
Once you’ve confirmed the leak, cover the lines with soap and look for bubbles to locate the holes and seal them.

How to diagnose a GMC Yukon climate control malfunction

When it comes to a malfunctioning climate control system, there are so many potential causes from a dirty evaporator to a bad blower motor or a blown fuse. Before you attempt any repairs, you need to properly diagnose the problem.
You can use an onboard diagnostics (OBD) scan tool to identify the source of the climate control malfunction and find the right solution. If you don’t own one, you can head to your local auto parts store to purchase one or borrow theirs.
Bringing your Yukon to a mechanic to have a professional diagnose the problem is another great option. Just be sure to check for the proper training and certifications for HVAC repairs beforehand.

How to keep GMC Yukon insurance costs low

Climate control system repairs are expensive, and with the average cost of GMC Yukon car insurance of $2,386 per year, there is no better time to shop around for new rates. 
Price comparison shopping is one of the best ways you can lower insurance costs because each company calculates insurance premiums differently, you could find savings by switching providers. 
If you’re hesitant to make the switch because you’re worried about the work involved, don’t be!
