How to replace the condenser fan relay

09.11.2022 /

The condenser fan relay controls the fan to remove heat from the motor. If it is defective, it will not allow the air conditioner to blow cold air or work at all.

The condenser fan relay and engine cooling fan relay are the same component on most vehicles. Some vehicles use separate relays for the condenser fan and radiator fan. For the purposes of this article, we will focus on a single relay that controls the operation of the cooling fan, which serves to remove excess heat from both the cooling system and the engine.

Electric cooling fans come in several configurations. Some vehicles use two separate fans. One fan is used for low airflow and both fans are used for strong airflow. Other vehicles use one fan with two speeds: low and high. These two speed fans are usually controlled by a low speed fan relay and a high speed fan relay. If the condenser fan relay fails, you may notice symptoms such as the air conditioner not blowing cold air or not working at all. In some cases, the car may overheat.

Part 1 of 1: Replacing the Condenser Fan Relay

Necessary materials

  • Relay removal pliers
  • Condenser Fan Relay Replacement
  • work light

Step 1: Locate the condenser fan relay.. Before you can replace this relay, you must first determine its location in your vehicle.

In most vehicles, this relay is located in the junction box or junction box under the hood. On some vehicles, this relay is located on the fender apron or firewall. The user manual will show you its exact location.

Step 2: Turn off the ignition key. Once you have identified the correct relay, make sure the ignition key is turned to the off position. You don't want electrical sparks to damage your car.

Step 3 Remove the condenser fan relay.. Use the relay removal pliers to firmly grasp the relay and gently pull it up, rocking the relay slightly from side to side to release it from its socket.

  • A warning: Do not use spline pliers, needle nose pliers, vise or any other pair of pliers for this task. If you don't use the right tool for the job, you will damage the relay housing when you try to remove it from the power distribution center. The relay removal pliers grip opposite corners of the relay or under the bottom edge of the relay, not the sides. This gives you more pull on the relay without damaging the sides.

Step 4: Install the new relay. Due to the terminal arrangement, an ISO relay like the one shown above can only be installed one way. Determine the relay connector terminals that match the terminals on the relay. Align the relay terminals with the relay socket and push the relay firmly until it snaps into the socket.

Replacing this relay is quite within the power of the average self-taught master. However, if you would rather have someone else do it for you, AvtoTachki certified technicians are available to replace the condenser fan relay for you.
