If your Lexus ventilated seats are not working, it may be due to a failure in the ventilation system or a problem with the seat control module.
Ventilated seats are a luxury feature found in many high-end vehicles including Lexus RX 350. They use small fans built into the seat and backrest to move air through the seat, enhancing comfort especially in warmer climates. Unfortunately, these seats can stop working due to various reasons, leaving you without the desired cooling effect.
One common issue is Hyundai, Lexus, and Audi vehicles, where the ventilated seats stop functioning due to a problem in the fan or its connection. The fans in these seats are intricate pieces of technology that can become jammed or fail over time. Also, if the wiring connecting the fan to the power supply is damaged or disconnected, it can result in a non-working ventilated seat.
Similarly, in Mercedes, Jeep Grand Cherokee, and Ram vehicles, a malfunctioning seat control module can be the cause. The seat control module is the device that regulates the fan speed and direction, and a fault here can render the entire system inoperative.
Despite these common problems, there’s a broad spectrum of potential causes why ventilated seats might not be working. Hence, if your cooled seats stop functioning, it’s advisable to seek help from a professional. This would ensure an accurate diagnosis and appropriate remedy to get your ventilated seats up and running once again.

A malfunctioning ventilated seat can impact the comfort and luxury Lexus owners have come to expect. This can be particularly evident during hot summer months when the cooling feature becomes essential.
Mechanics Behind Lexus Ventilated Seats
Let’s take a look at how Lexus ventilated seats operate. They are comprised of an array of components that work together to deliver optimal cooling.
Functionality of Ventilated Seats
The ventilated seats work by using a series of fans within the seat itself, drawing in cool cabin air and circulating it through the seating material. This process cools down the surface of the seat, providing relief from the heat.
Key Components of Lexus Ventilated Seats
