how to fix the air conditioning not blowing cold air in Toyota Camry Seventh Generation (2012-2017)

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure vehicle is parked on a flat surface and the engine is off.
• Wear safety goggles and gloves for protection.

2. Checking Refrigerant Levels

• Connect a manifold gauge set to the low and high-pressure ports of the AC system.
• Start the engine and turn on the AC to the maximum setting.
• Check the refrigerant levels; they should be within the specified range for R134a (typically 30-40 psi on the low side, 200-250 psi on the high side).
• If the levels are low, proceed to the next step.

3. Recharge the AC System

• Purchase the correct R134a refrigerant and a recharge kit.
• Attach the recharge hose to the low-pressure service port.
• Follow the instructions on the recharge kit to add refrigerant until the correct pressure is achieved.
• Monitor the temperature from the vents; it should begin to cool.

4. Inspecting and Replacing the Cabin Air Filter

• Locate the cabin air filter compartment (usually behind the glove box).
• Remove the glove box to access the filter.
• Take out the old cabin air filter and inspect it for dirt or clogs. Replace if necessary.
• Reinstall the glove box.

5. Inspecting and Testing the AC Compressor

• Check the AC compressor for signs of damage or wear.
• Use a multimeter to test the electrical connections to the compressor.
• If the compressor is not engaging, consider replacing it with a new unit.
• Ensure that the new compressor is properly lubricated with the correct amount of oil.
