my Ford F-150 14th Generation (2021-2024) AC is not blowing cold air how can I fix it

Solution

1. Preparation

• Gather all necessary tools and parts.
• Ensure the vehicle is parked on a level surface.
• Disconnect the battery to prevent electrical shocks.

2. Recharge Refrigerant

• Tools Required: Manifold gauge set, refrigerant (R-134a), vacuum pump.
• Connect the high and low-pressure hoses of the manifold gauge set to the respective service ports on the AC system.
• Start the engine and turn the AC to maximum cool.
• If the pressure is low, vacuum the system for 15-30 minutes to remove any air and moisture.
• Recharge the system with the correct amount of R-134a refrigerant as specified in the owner’s manual (usually around 1.5 to 2.0 pounds).

3. Repair or Replace AC Components

• Tools Required: Socket set, wrenches, AC compressor removal tool (if needed).
• If the AC compressor is found to be defective, remove the belt and disconnect the electrical connector.
• Remove the compressor mounting bolts and take out the old compressor.
• Install the new compressor, ensuring to replace the O-rings with new ones and adding the appropriate amount of oil if required.
• Reconnect the electrical connector and install the drive belt.

4. Inspect and Test System

• Tools Required: Leak detection dye, UV light.
• After recharging or replacing components, add a leak detection dye to the system.
• Run the AC for 10-15 minutes and then use a UV light to check for any leaks in the system.
• If leaks are detected, repair the affected hoses or connections.
