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 negative battery terminal for safety.
2. Recharge AC System
  • Tools Required: Refrigerant can, manifold gauge set, AC refrigerant recovery machine (if necessary).
  • Check refrigerant levels using the manifold gauge set. If low, proceed to recharge:
    • Connect the refrigerant can to the low-pressure service port.
    • Open the valve and allow refrigerant to enter the system until proper levels are reached (typically 30-45 psi on the low side).
    • Disconnect the refrigerant can and recheck the system pressures.
3. Inspect and Replace Components
  • Tools Required: Socket set, wrench set, screwdriver set.
  • If the compressor is not engaging:
    • Check the compressor clutch. If it’s not engaging, inspect the electrical connections and the AC relay.
    • If the relay is faulty, replace it.
    • If the compressor is damaged, it may need replacement.
4. Replace Cabin Air Filter
  • Tools Required: Flathead screwdriver (if applicable).
  • Locate the cabin air filter housing (usually under the dashboard).
    • Remove any screws or clips securing the housing.
    • Pull out the old cabin air filter and replace it with a new one.
    • Reassemble the housing and secure it with screws.
