AC Relay Location

The AC relay in a 2017 Honda CR-V is located in the engine compartment fuse box. This fuse box is positioned on the left side of the engine bay, near the brake fluid reservoir. To access the AC relay:

1. Open the hood of your Honda CR-V

2. Locate the main fuse box on the driver's side of the engine compartment

3. Remove the fuse box cover by pressing the tabs and lifting it off

Once you've opened the fuse box, you'll notice that the relays are not clearly labeled. However, the AC relay can be identified by looking for a relay with a snowflake or ice crystal symbol on it. This symbol represents the air conditioning system.

Identifying the AC Relay

The AC relay is crucial for the proper functioning of your vehicle's air conditioning system. It controls the power supply to the AC compressor. If you're experiencing issues with your AC, checking this relay is a good starting point for troubleshooting.

To help you locate the AC relay more easily, look for these characteristics:

  • A cube-shaped component
  • Typically larger than fuses
  • Often has a plastic housing
  • Located among other relays in the fuse box

Additional AC-Related Components

While checking the AC relay, it's worth noting other AC-related fuses and components:

  • Fuse #23: This 10A fuse is responsible for the A/C Compressor and Upper Shutter Grille
  • Fuse #9: A 10A fuse in the interior fuse box that controls the air conditioning system

If you're experiencing AC issues, checking these fuses along with the relay can help diagnose the problem.

Replacing the AC Relay

If you determine that the AC relay needs replacement:

1. Ensure the vehicle is turned off and the key is removed

2. Carefully pull the old relay straight out of its socket

3. Insert the new relay, making sure it's oriented correctly and fully seated

Always consult your vehicle's manual or a professional mechanic if you're unsure about performing any maintenance tasks.
