#2- Fix Frozen Evaporator Coil

The evaporator is among the most crucial components of the automotive air conditioner. Its main duty is to collect heat from the ambient air. 

A frozen evaporator is typically caused by the AC allowing humidity, dust, or other outside elements to enter the evaporator. Due to a malfunctioning AC evaporator, AC lines may freeze and reduce airflow. 

There are several precautions you should take in order to avoid having the AC evaporator coil freeze, and these are as follows:

  • Replace the air filter every month. 
  • Examine the vents.
  • Enhance the fan’s power.
  • Check the coolant level.
  • Examine the condensation drain regularly.

It is also simple to thaw out an already-frozen evaporator coil. If you are skilled enough, you can accomplish this at home. To defrost it, turn off the engine and allow the evaporator coils to thaw out. Additionally, you may speed up the melting of the ice by using a hair dryer. The coil will be damaged if you use a sledgehammer or any other tools to break up the ice.

The AC coil may totally defrost in two to twenty-four hours. However, this depends on the thawing procedure, the AC, as well as the thickness of the AC coils. You don’t need to waste any money on this process.

#3- Clean Dirty Evaporator Coil

An air conditioning unit in your automobile has to be maintained as a part of your regular auto maintenance. Cleaning the evaporator coil is among these AC maintenance tasks since a filthy evaporator will release airborne pollutants into the cabin of your car. This will also reduce the cold air flow into the vehicle.

The evaporator coil has to be thoroughly cleaned if you discover that it has gotten too unclean. If you take it out of its location, cleaning it can be rather simple. However, this method could take a lot of effort and time.

For this reason, we will outline a step-by-step process that might assist you in effectively cleaning it without removing it.

  • Step 1: To reach the AC evaporator coil, remove the glove box from your jeep wrangler.
  • Step 2: After that, cover the whole evaporator coil with the cleaner and make sure to complete this process thoroughly. Then immerse the evaporator coil in the cleaning solution for 20 minutes to help the cleaner to work effectively.
  • Step 3: Using fresh water and a towel, thoroughly clean the evaporator coil and wipe away any remaining moisture.
  • Step 4: Finally, gently put the glove box back in place.

#4- Clean Or Replace The Blower

The purpose of a blower mechanism is to maintain air flowing both into and out of the AC unit, but with time, dirt can accumulate on the rotors. Based on utilization and the driving condition, most blower units require removal and cleaning every three to five years.

A filthy blower unit can significantly impact your AC unit’s airflow, which might lead to an overheated heat exchanger and frozen AC coils. Additionally, it will reduce the effectiveness of the overall AC system and the ability to blow cold air.

Here are a few warning indicators of a defective Jeep Wrangler blower unit:

  • Burning odor or smoke while driving.
  • Unusual noises are coming from the AC unit.
  • The fan only blows at a specific speed.
  • The Blower motor airflow is inadequate.

You must inspect the blower unit if you discover that the AC is not blowing strongly. The first thing to do is thorough cleaning if you discover dirt within. You can complete this process without spending any money.

A blower motor may become damaged from time to time, in which case you must replace it with a new one. Unfortunately, it’s rather difficult to replace a blower motor by yourself; that’s why professional assistance is required, which may cost you around $100 to $300.

#5- Recharge The AC System

It could be required to refill the unit with fresh refrigerant if the air conditioning loses its capacity to cool effectively. Due to the fact that Jeep Wrangler employs r134a refrigerant, you may recharge the unit on your own using a recharging kit.

You can easily and quickly recharge your air conditioner by yourself at a reasonable price. This is among the quickest and simplest automobile maintenance jobs to complete, but if done wrong, it might lead to issues with the cooling system. Therefore, before moving on, thoroughly read these step by step carefully.

  • Step 1: Initially, find the service port. Normally, the line that connects the compressor and accumulator does have this port. And ensure a solid connection between the charging hose and the service port.
  • Step 2: Next, switch on the engine and maximize the air – conditioning system. Now, begin refilling the unit with coolant if the pressure is too low and continue doing so until it reaches the ideal level.
  • Step 3: Disconnect the recharging line from the service port once the air conditioner has been filled to the appropriate pressure. Keep the can connected to the recharge hose, and preserve the extra coolant in a cold, dry place.

If you hire a professional technician for this, it will often cost you between $150 and $300. However, the auto AC recharging kit would cost approximately $40 to $50 if you decide to do it yourself.

#6- Inspect And Repair Refrigerant Leak

The word “refrigerant or coolant” refers to the liquid that circulates throughout an ac system to collect and radiate heat. To function in an AC system properly, the refrigerant has to have a specific quantity. Maybe there is a leak somewhere else if your refrigerant levels are dropping after frequent refills.

In a well-sealed AC system, the coolant should theoretically never leak, but most automotive Cooling systems do lose a tiny amount of overtime because of minor flaws, and they need to be recharged every few years.

Signs of refrigerant leaks:

  • From the inside unit, there are hissing noises.
  • The air conditioning unit stops cooling.
  • The air conditioner is not blowing strongly.

Luckily, it’s not too difficult to repair an AC refrigerant leakage. In accordance with the nature of the leak, there are two methods to solve this. Sealing the leakage hole will stop minor leaks, and this might cost you around $5 to $10. 

Larger leaks require expert repair since they cannot be repaired. The compressor will probably need to be replaced in this situation. Depending on the model of your automobile, you may anticipate spending around $370 to $750 on components and labor.

#7- Examine And Repair Faulty Condenser Fan

In order for the coolant to circulate through the AC system, it must first be changed from a gas into a liquid by the AC condenser. The purpose of the AC condenser fans is to maintain the condenser’s cooling so that it may continue to effectively turn gas into a liquid and maintain the AC system’s proper operation.

A malfunctioning fan might lead to issues with the overall AC system. The temperature and pressure would increase considerably if the condenser’s fan failed to cool it, which makes the condenser more susceptible to failing. It also has an impact on the air quality of the air conditioner.

Signs of a faulty condenser fan: 

  • Although the AC is on, the fan won’t turn on.
  • After switching off the AC, the fan won’t stop.
  • When the fan is running, the condenser unit makes a rattling sound.
  • While idle, your Jeep heats up.
  • Even though the fan is running, the blades are moving extremely slowly.
  • Burning odor when the air conditioner is running.

In this case, replacing the defective fan is the recommended course of action. The cost of replacing an AC condenser fan ranges from $300 to $425 on average. Depending on the year and type of your Jeep, components price can be around $200 to $300, whereas labor costs might range from $80 to $150.
