A/C Relays, Sensors & Switches

A/C Relays, sensors and switches are some of the smallest, most delicate, links of the A/C system chain. However, a chain is only as strongest as its weakest link. So it is a best practice to replace old warn parts before they cause catastrophic failure! Some of these parts include, but are not limited to: fan relay, blower motor relay, ambient air sensors, and A/C and heat control switch.

If your ambient air temperature sensor is malfunctioning you would never know how hot or cold it is outside, and neither would your A/C control module! The same goes for your interior air sensor and humidity sensors. A lot of hard work and engineering produced these intricate climate systems. Incorrect or a complete lack of information will drastically affect performance of them. Error or fault codes on your dash can be just as irritating as uncomfortable temperatures in your vehicle, a simple sensor replacement is a quick and easy solution!

When a relay goes bad it will cut off or hinder the operation of its respective part. If a fan relay goes bad, no more fan! If a blower motor relay goes bad, no more blower motor! Why replace a possibly perfect working fan or blower motor before checking if the relay went bad? The same idea applies to switches as well. If your A/C and heat control switch is going bad it could either cause the heat to come on instead of the A/C, vice versa, or neither at all! You don’t want to be caught in the middle of summer or winter with a scenario like that!

Replacing the bigger and more expensive parts can be meaningless and time consuming if you have a faulty relay, sensor, or switch that is preventing the proper function of that particular part. There are many of these placed throughout the A/C system so one bad part could cause a chain reaction that could potentially cripple the entire system. Accurate diagnosis is an imperative step in the replacement process and should always be handled with care.
