Toyota 4Runner A/C Relays, Sensors & Switches

In the past, hot summer days could turn your time behind the wheel into hell, but everything has changed with the introduction of air conditioning. Some of the first automotive A/Cs were created in 1933, but they were installed mostly on luxury vehicles. In 1953, modern-like air conditioning systems that can make you feel fresh and comfortable on a boiling day were introduced. All you have to do is press the button, and cold and refreshing air will fill your cabin. Everybody knows that control units, compressors, and evaporators are the main parts of the A/C system in your Toyota 4Runner, but there are other small yet essential components.

A system is only as strong as its weakest link. That is why it is so important to make sure that you’re A/C relays, switches, and sensors are in top condition. A/C sensors provide your control unit with the information about the outside temperature enabling it to make appropriate adjustments of the temperature in the cabin. Relays serve as connectors between bigger components while switches allow you to control you’re A/C. Should any of these parts fail, you can replace them with our premium-quality Toyota 4Runner A/C relays, sensors, and switches by some of the most reputable brands in the industry.
