During the summer months, there is nothing more important to a car owner than a properly working air conditioner system. Most car owners are unaware about just how many components have to work together in order for cold air to blow out of the vents. The blower motor relay is what cuts on the blower to release the cold air into the cabin of the car. When you turn on the switch in your car to activate the air conditioner, the blower relay will turn on and release the power needed to turn on the blower fan. This part of your car is only used when the air conditioner is turned on.
This relay is usually located under the hood of the car in the relay and fuse box. The heat of the engine, mixed with the ongoing use that this relay gets is what usually leads to it going bad. Nearly all of the relays on a car, including the blower motor relay are built to last for as long as the car does. While they are built to last this long, they seldom do because of the harsh conditions they are exposed to on a constant basis.
The only way that you will be able to get the cool air needed in the cabin of your car is by having a properly working blower motor relay. In some instances, the symptoms that you will notice when the relay has gone bad are the same as when the blower switch goes bad. The following are some of the signs you will notice when it is time to get your blower motor relay replaced.
- The blower function on the car’s A/C is not working
- The blower only works on occasion
- The inability to run the blower on higher settings
- The blower changes speeds without being messed with
Rather than having to deal with the heat outside without a working blower, you will have to act when the signs of a bad blower relay surfaces. Having a professional to troubleshoot the issues you are experiencing will help to ensure that the right repairs are performed and the blower motor relay is replaced if needed.
