Problem Statement

Learn how to diagnose and fix the AC not getting cold in Ford Explorer Fifth Generation (2011-2019). Step-by-step guide with tools and parts required.

Affected Component

HVAC

Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always disconnect the battery before working on electrical components
•Follow refrigerant handling guidelines to avoid exposure and environmental harm

Symptoms

•AC blows warm air instead of cold
•Unpleasant odors emanating from the AC vents
•Reduced airflow from the AC system
•AC compressor not engaging
•Noticeable refrigerant leaks under the vehicle
•Frequent cycling of the AC compressor

Diagnostic Steps

1
Scan for error codes using an OBD-II scanner to check for AC-related diagnostic trouble codes (DTCs)
2
Inspect the AC refrigerant level using a refrigerant gauge to determine if the system is low on refrigerant
3
Check the AC compressor operation by observing if the clutch engages when the AC is activated
4
Examine the AC condenser for blockages, debris, or damage that could impede airflow
5
Inspect the cabin air filter for clogs or restrictions that may reduce airflow into the cabin
6
Test electrical connections to the AC compressor and other related components with a multimeter to ensure proper voltage and ground

Solution

💡 Expert Tip

For complex repairs like this, consider taking photos at each step. This helps if you need to reverse a step or consult with a mechanic. Also, keep all removed parts organized - you may need to reference them during reassembly.

Verification

After completing the repair, verify that the issue has been resolved:

✓Test the affected component to ensure it functions correctly
✓Check for any error codes or warning lights
✓Monitor the vehicle for a few days to ensure the issue does not recur

Prevention Tips

To prevent this issue from occurring again:

•Follow the manufacturer's recommended maintenance schedule
•Address warning signs early before they develop into major issues
•Use quality parts and fluids recommended for your vehicle
•Keep detailed records of all repairs and maintenance

Tools & Equipment Required

•OBD-II scanner
•Refrigerant recovery machine
•Refrigerant gauge set
•Multimeter
•Socket set
•Torque wrench

Parts Required

•AC compressor (if faulty)
•Receiver-drier or accumulator
•Refrigerant (R-134a)
•O-rings and seals

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Safety: Wear safety goggles and gloves.

2. Recover Refrigerant

Connect a refrigerant recovery machine to the AC service ports.
Recover any remaining refrigerant from the system to prevent environmental contamination.

3. Inspect and Replace Components

Check the compressor:
- If the compressor is faulty, disconnect the electrical connector and remove the mounting bolts.
- Install the new compressor and torque the bolts to manufacturer specifications (typically around 18-25 ft-lbs).
Replace the receiver-drier or accumulator:
- Remove old components and replace with a new unit, ensuring all seals are lubricated and connections are tight.

4. Recharge the AC System

Using a refrigerant gauge, charge the AC system with the correct type and amount of refrigerant (usually R-134a).
Monitor the low and high side pressures, ensuring they are within manufacturer specifications.

5. Test the System

Reconnect the battery and start the engine.
Turn the AC to maximum and verify that the compressor engages and cold air is produced.
