The summer season is here, and with it comes the scorching heat that makes life unbearable. As a car owner, you must be aware of the importance of maintaining your vehicle’s air conditioning system to keep you cool and comfortable while driving. However, if your car drips water when the AC is on, it can be a cause of concern. In this blog post, we will delve into the reasons behind this issue and provide you with a comprehensive guide on how to troubleshoot and fix the problem.
Car drips water when the AC is on is a common issue that many car owners face, and it can be frustrating and inconvenient. The water drip can be due to various reasons, including a faulty condenser coil, a clogged drain tube, or a malfunctioning evaporator core. In some cases, the issue may be more serious and require professional attention. Therefore, it is essential to identify the root cause of the problem and take prompt action to resolve it.

What Causes Car Drips Water When AC Is On?
The air conditioning system in your car is designed to cool the air by using a refrigerant that changes state from liquid to gas. The process involves the circulation of refrigerant through the system, which can cause condensation to occur. This condensation can result in water droplets forming inside the system, which can drip out when the AC is turned on.
Condenser Coil Issues
The condenser coil is responsible for dissipating the heat from the refrigerant as it changes state from liquid to gas. If the coil is clogged or dirty, it can cause the refrigerant to overheat, resulting in excessive condensation and water dripping from the system.
- Clogged condenser coils can be caused by debris, dirt, or rust buildup.
- A dirty condenser coil can reduce the airflow and cause the system to work harder, leading to increased condensation.
Clogged Drain Tube
The drain tube is responsible for removing condensation from the system. If the tube is clogged or blocked, it can cause water to accumulate inside the system, resulting in dripping when the AC is turned on.
- A clogged drain tube can be caused by debris, dirt, or mineral buildup.
- A blocked drain tube can cause water to back up into the system, leading to dripping and potentially causing damage to the electrical components.
Evaporator Core Malfunction
The evaporator core is responsible for cooling the air inside the car. If the core is malfunctioning or clogged, it can cause the system to produce excessive condensation, resulting in water dripping from the system.
- A malfunctioning evaporator core can be caused by a faulty thermostat, a clogged air filter, or a malfunctioning blower motor.
- A clogged evaporator core can cause the system to produce excessive condensation, leading to dripping and potentially causing damage to the electrical components.

Before attempting to fix the issue, it is essential to identify the root cause of the problem. Here are some steps you can follow to troubleshoot the issue: (See Also: Why Does My Car Ac Only Blow Hot Air? Common Causes Revealed)
Step 1: Check the Condenser Coil
Start by checking the condenser coil for any signs of damage, rust, or corrosion. If the coil is damaged, it may need to be replaced. You can also use a garden hose to spray the coil and check if it is clogged or dirty.
| Signs of Damage | Actions to Take |
|---|---|
| Rust or corrosion | Replace the condenser coil |
| Clogged or dirty | Clean the coil with a garden hose |
Step 2: Check the Drain Tube
Next, check the drain tube for any signs of blockage or clogging. You can use a flashlight and a cloth to inspect the tube and check if it is clear. If the tube is clogged, you can use a wire hanger to clear the blockage.
| Signs of Blockage | Actions to Take |
|---|---|
| Blockage or clogging | Use a wire hanger to clear the blockage |
Step 3: Check the Evaporator Core
Finally, check the evaporator core for any signs of malfunction or clogging. You can use a thermometer to check the temperature of the air coming out of the vents. If the temperature is higher than normal, it may indicate a malfunctioning evaporator core.
| Signs of Malfunction | Actions to Take |
|---|---|
| Malfunctioning or clogged | Replace the evaporator core |
How to Fix Car Drips Water When AC Is On?
Once you have identified the root cause of the problem, you can take the necessary steps to fix the issue. Here are some steps you can follow to fix the problem:
Step 1: Clean the Condenser Coil
If the condenser coil is clogged or dirty, you can clean it using a garden hose. Make sure to spray the coil from the outside and avoid spraying the coil from the inside, as this can cause damage to the electrical components.
