my Ford F-150 Fourteenth Generation (2021-present) AC is blowing hot air what should I do

Solution

1. Preparation

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

2. Recharge AC System

• Tools Required: AC manifold gauge set, refrigerant (R-134a), refrigerant scale.
• Connect the low and high-pressure hoses of the AC manifold gauge set to the corresponding ports on the AC system.
• Start the engine and turn the AC to the maximum setting.
• Monitor the readings on the gauge; if the refrigerant level is low, proceed to recharge.
• Add refrigerant slowly while monitoring the pressures, ensuring not to overfill (refer to the vehicle's specifications for the correct amount).

3. Repair or Replace AC Components

• Tools Required: Socket set, wrenches, AC compressor oil.
• If the compressor is faulty, remove the serpentine belt by releasing tension from the tensioner pulley.
• Unbolt the AC compressor from its mounting brackets and disconnect the electrical connector and refrigerant lines (ensure proper recovery of refrigerant).
• Replace with a new compressor, ensuring to lubricate it with AC oil before installation.
• Reconnect all components and refill the refrigerant if necessary.

4. Inspect and Replace Cabin Air Filter

• Tools Required: None.
• Locate the cabin air filter access panel, typically found behind the glove compartment.
• Remove the filter and inspect for dirt and debris.
• Replace with a new, clean cabin air filter to ensure proper airflow.
