Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the vehicle battery to prevent electrical shock.
  • Ensure the vehicle is on a flat surface and securely positioned.
2. Inspect Cabin Air Filter
  • Remove the cabin air filter cover (usually located behind the glove box).
  • Take out the cabin air filter and inspect it for debris, discoloration, or burning.
  • If dirty or damaged, replace it with a new filter.
3. Check AC Compressor
  • Locate the AC compressor under the hood.
  • Inspect for any signs of oil leakage, physical damage, or unusual noise while the AC is running.
  • If the compressor is damaged, replace it according to the manufacturer's specifications.
4. Verify Refrigerant Levels
  • Use a manifold gauge set to check the refrigerant levels.
  • If levels are low, locate and repair any leaks, then recharge the system with the appropriate refrigerant type.
5. Inspect and Repair Wiring
  • Check all wiring connections near the AC compressor and blower motor.
  • Look for frayed wires or burnt connections. Repair or replace any damaged wiring.
6. Check Blower Motor
  • Remove the blower motor from its housing.
  • Inspect for any signs of burning or overheating.
  • If damaged, replace the blower motor, ensuring proper alignment and secure installation.
