Frequently Asked Questions (FAQs)
1. How do I know if my blower motor relay is bad?
You can identify a bad blower motor relay through several symptoms. One common sign is when the blower motor does not function at all. Another indication is a blown AC blower motor relay circuit fuse. Additionally, a melted relay is also an indicator of a faulty blower motor relay.
2. What does a blower motor relay do in a vehicle?
The blower motor relay plays a crucial role in the vehicle's HVAC system. It activates the blower motor, allowing cold air to be released into the cabin of the car. Without the blower motor relay, the blower motor would not function properly, and cold air would not be circulated.
3. What causes a blower motor relay to fail?
Blower motor relays can fail due to exposure to high current loads. Overheating can cause the interior components and plastic housing of the relay to melt and burn, potentially damaging the fuse box or panel. This can occur when the relay develops problems or is subjected to excessive electrical stress.
4. What happens when the blower motor resistor goes out?
When the blower motor resistor fails, it can result in the inability to get air to come out of the vents. The blower motor resistor controls the power to the blower motor. When it malfunctions, it can cut off all power to the motor, preventing air pressure from being produced.
5. Is there a fuse that controls the blower motor?
Yes, there are fuses that control the blower motor. Most vehicles have two fuses for the blower motor, one in the interior fuse block and the other under the hood. It is recommended to check these fuses if the blower motor is not working properly before assuming there is a problem with the motor itself.
6. What fuse controls the blower motor?
The fuse that controls the blower motor is typically a 20-, 25-, or 30-amp fuse located in the fuse panel under the dash. The specific rating of the fuse depends on the vehicle and the power requirements of the blower motor at full speed.
