my Honda CR-V's air conditioning is not blowing cold air what to check

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the vehicle's battery to ensure safety while working on electrical components.

2. Check and Recharge Refrigerant

• Sub-steps:
  1. Connect a refrigerant gauge set to the low-pressure service port.
  2. Read the pressure; if low, proceed to recharge.
  3. Use a refrigerant canister with a recharge hose, and add refrigerant according to the manufacturer's specifications (typically R-134a for older models).
  4. Monitor the pressure while adding to avoid overcharging.

3. Inspect and Replace Components

• Sub-steps:
  1. Inspect the AC compressor for signs of wear or failure.
  2. If the compressor is not engaging, check the electrical connections and replace any damaged wiring.
  3. Replace the AC compressor if necessary, following these steps:
     • Remove the serpentine belt by loosening the tensioner.
     • Unbolt the AC compressor from its mounting bracket.
     • Disconnect the refrigerant lines (ensure system is evacuated before disconnecting).
     • Install the new compressor and reconnect refrigerant lines.
     • Reinstall the serpentine belt.

4. Replace Cabin Air Filter

• Sub-steps:
  1. Locate the cabin air filter access panel (usually behind the glove box).
  2. Remove the panel and take out the old air filter.
  3. Insert a new cabin air filter, ensuring it is oriented correctly.
  4. Reattach the access panel.
