The air conditioner in the 2004 Trailblazer can have several different problems. The most common problem is that the air conditioner will not blow cold air. This can be caused by a few different things.
One possibility is that the Freon levels are low. Another possibility is that the compressor is not working properly. If the compressor is not working, it will need to be replaced.
If you own a 2004 Chevrolet Trailblazer, you may have experienced problems with the air conditioner. The most common problem is that the AC will blow warm air when it is turned on. This can be caused by a variety of factors, including low refrigerant levels, leaks in the system, or faulty components.
If you are having this problem, there are a few things you can do to try to fix it yourself before taking it to a mechanic.
First, check the level of refrigerant in the system. If it is low, you will need to add more in order to get the AC working properly again.
You can buy refrigerant at any auto parts store. Be sure to follow the instructions on the can carefully so that you don’t overfill the system.
Next, check for leaks in the system.
A leaky air conditioner will not cool your car effectively and can actually make the problem worse over time. To check for leaks, put some soapy water on all of the fittings and connections and look for bubbles. If you find a leak, tighten up the fitting or connection and see if that stops the leak.
If not, you may need to replace that part ofthe system.
Finally, if your AC is still blowing warm air after checking these things, there may be an issue with one ofthe components inside ofthe unit itself such as the compressor or evaporator coil.

How Do You Reset an Ac Trailblazer?
If your AC trailblazer isn’t working properly, you may need to reset it. To do this, first make sure that the batteries are charged and that all the connections are secure. Next, press and hold the “RESET” button for three seconds.
After that, release the button and wait for the lights on the control panel to flash. Once they stop flashing, your AC trailblazer is reset and should be working properly again.
What are Signs That Your Ac Compressor is Going Out?
As the heart of your air conditioning system, your AC compressor works hard to keep you cool all summer long. But like any mechanical component, it can wear out over time. Here are some telltale signs that your AC compressor is going out and needs to be replaced:
1. Your air conditioner isn’t cooling as well as it used to. If you notice that your AC unit isn’t blowing as cold of air as it used to, or if it takes longer to cool down your home, then this could be a sign that your compressor is failing.
2. You hear strange noises coming from your AC unit.
If you start to hear loud banging, grinding, or squealing noises coming from your air conditioner, these could be signs that the compressor is failing and needs to be replaced.
3. Your energy bills have gone up unexpectedly. If you see a spike in your energy bills with no change in usage, then this could mean that your AC unit is working harder than usual due to a failed compressor.
4. The coils on your AC unit are frozen. Another sign that something is wrong with your compressor is if the coils on your AC unit become frozen over time.
What is the Common Problems for a 2004 Chevy Trailblazer?
One of the most common problems with the Chevy Trailblazer is transmission failure. This can occur for a variety of reasons, but often it is due to a buildup of sludge and debris in the transmission fluid. This can cause the transmission to slip or jerk, and eventually fail entirely.
If you notice any issues with your Trailblazer’s transmission, it’s important to have it checked out by a mechanic as soon as possible.
Another common problem with the Chevy Trailblazer is engine overheating. This can happen due to a leak in the cooling system, a failed water pump, or simply because the radiator needs to be flushed and refilled.
If your engine overheats, it’s important to pull over and turn off the engine immediately to prevent damage. Once the engine has cooled down, you’ll need to take it to a mechanic to have it inspected and repaired.
Finally, another issue that plagues many Chevy Trailblazers is electrical problems.
Everything from faulty headlights to wonky windshield wipers can be caused by electrical issues. Often times these problems are due to loose or corroded wires, so it’s important to have them checked out by a qualified mechanic if you notice any issues.

Trailblazer Ac Reset
If your Trailblazer is acting up and you need to reset the system, there are a few things you can do. First, try disconnecting the negative battery cable for about five minutes. If that doesn’t work, you can also remove the fuse for the ECM/PCM.
This will disable the engine and allow you to restart it without all of the computer systems running. You may want to consult your owner’s manual before doing either of these things.

This article will show you how to check your refrigerant level and add Freon if needed.
2002 Chevy Trailblazer Air Conditioning Problems
If your 2002 Chevy Trailblazer is having air conditioning problems, there are a few things you can do to try and fix the issue. First, check the coolant level in the radiator. If it’s low, add more until it reaches the “full” line.
Next, check the AC compressor belt to make sure it’s tight enough. If it looks loose, tighten it using the adjustment screws on either side of the belt. Finally, check the Freon level in the system using a gauge.
If it’s low, you’ll need to have someone recharge your AC system with Freon.
2004 Chevy Trailblazer Ac Pressure Switch Location
If you’re looking for the AC pressure switch on your 2004 Chevy Trailblazer, you’ll find it on the compressor. It’s a small black switch that controls the flow of refrigerant in the system. If the switch is defective, it can cause the AC compressor to overheat and fail.
How Much Freon Does a Trailblazer Hold
If your Chevy Trailblazer is low on Freon, you may be wondering how much does it hold? The short answer is that it holds about 2.5-3 pounds of Freon. Keep in mind that the amount of Freon your Chevy Trailblazer needs will vary depending on the year and model.
The first thing you need to do is locate the low pressure service port. On most models, it’ll be on the passenger side near the firewall. Once you’ve found it, unscrew the cap and use a pressure gauge to check how much Freon is in your system.
If it’s below 25 psi, then you’re low and will need to add more.
To add more Freon, simply attach the can to the low pressure service port using the provided hose. Make sure that you don’t overfill it–stop when the gauge reads between 35-45 psi.
2005 Chevy Trailblazer Ac Not Blowing Cold Air
If you’re driving a 2005 Chevy Trailblazer and your air conditioner isn’t blowing cold air, there are a few potential causes. First, check to see if the A/C compressor is engaged. If it’s not, the problem could be with the A/C clutch or fuse.
Next, check the refrigerant level. If it’s low, adding more may do the trick. Finally, if none of these solutions work, it’s possible that there’s an issue with the A/C condenser or evaporator.
2008 Trailblazer Ac Blowing Hot Air
If you own a 2008 Chevy Trailblazer, you may have noticed that the air conditioner isn’t blowing as cold as it used to. In fact, it might be blowing hot air. This is a common problem with these vehicles, and there are a few things that can cause it.
One possibility is that the Freon level is low. The Freon is what makes the air cold, so if it’s low, the air will be warm. You can check the Freon level yourself by looking at the gauge on the AC compressor; if it’s in the red zone, then it’s time to add more Freon.
Another possibility is that there could be a leak in one of the AC hoses. This would allow Freon to escape, lowering the amount available to make the air cold. A visual inspection should reveal any leaks, but you’ll likely need a professional to fix them.
Finally, another potential issue is that the compressor itself could be failing. If this is the case, then replacing the compressor will be necessary to get your AC working properly again.
If your Trailblazer’s AC isn’t blowing cold air like it used to, don’t despair!
There are a few things that could be causing the problem and they can all be fixed relatively easily (and affordably).
Conclusion
If your 2004 Chevy Trailblazer is having air conditioning problems, there are a few things you can check before taking it to a mechanic. First, make sure the air conditioner is turned on and that the temperature setting is low enough. Next, check the air conditioner’s belt to see if it needs to be tightened or replaced.
Finally, examine the Freon levels in the system and add more if necessary. If these simple steps don’t fix the problem, then it’s time to take your car to a mechanic for further diagnosis.
