Learn how to diagnose and fix the AC not blowing cold air in Ford Explorer (2020-present). Step-by-step guide with tools and procedures included.

Affected Component

HVAC

Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the battery to prevent any electrical shorts.
•Wear safety goggles and gloves when handling refrigerant.

Symptoms

•AC blows warm air instead of cold
•Strange noises coming from the AC compressor
•AC compressor does not engage
•Visible refrigerant leaks around AC components
•Poor airflow from the vents
•AC system runs intermittently or cycles on and off

Diagnostic Steps

1
Scan for error codes using an OBD-II scanner to check for any fault codes related to the AC system.
2
Inspect the AC compressor for any physical damage or signs of failure, such as leaks or unusual noises.
3
Check the refrigerant levels using a manifold gauge set to ensure they are within manufacturer specifications.
4
Test the AC system's electrical components, including fuses and relays, to ensure they are functioning properly.
5
Inspect the cabin air filter for clogs or debris that may restrict airflow.
6
Check for any blockages or restrictions in the AC lines or evaporator core.

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

Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery to prevent any electrical shorts.

2. Recharge the AC System

Tools Required: Manifold gauge set, refrigerant (R-134a or R-1234yf depending on the system), safety goggles, gloves.
Connect the low and high-pressure sides of the manifold gauge set to the respective service ports.
Check the pressure readings against manufacturer specifications; if low, proceed to add refrigerant.
With the engine running and AC set to maximum, slowly add refrigerant until proper pressure is achieved.
Disconnect the manifold gauge set and recap the service ports.

3. Replace the Cabin Air Filter

Tools Required: Screwdriver or trim removal tool.
Locate the cabin air filter access panel (usually under the dashboard or behind the glove compartment).
Remove the access panel by unscrewing or unclipping it.
Take out the old cabin air filter and check the housing for debris.
Install the new cabin air filter, ensuring it's oriented correctly.
Reattach the access panel securely.

4. Inspect and Replace the AC Compressor (if needed)

Tools Required: Socket set, AC compressor clutch removal tool, torque wrench.
Remove the drive belt from the AC compressor by loosening the tensioner.
Disconnect the electrical connector and refrigerant lines from the compressor.
Remove the mounting bolts securing the compressor to the engine.
Install the new AC compressor by reversing the removal steps, ensuring to torque bolts to manufacturer specifications.
Reconnect the refrigerant lines and electrical connector, then reinstall the drive belt.
