FAQs

Where is the fuse on a Freightliner blower motor? ›

The fuse panel is on the passenger side, in the dash, remove the cover and you will see the fuses. You will see 2 un marked fuses, a 5 amp fuse, and a 30 amp fuse. the 5 amp fuse is for the a/c controller, and the 30 amp fuse is for the blower motor.

The AC fuse on most HVAC systems is typically on the unit's control board. You'll normally find the board behind an access panel on the unit's lower compartment. While you sometimes have to unscrew areas to access the control board, others have clips.

Many vehicles have two fuses for the blower motor, one in the interior fuse block and the other under the hood. The blower motor is usually under the dashboard on the passenger side.

It is usually located inside the blower compartment on the side of the blower motor. Be cautious, as the housing may be hot. If the button is popped up, press it down.

Use voltmeter or ohmmeter to check for a blown fuse. If you find one, replace it. Start car and see if the blower motor works. If fuse blows again, check for loose circuits.

Car AC Not Blowing Cold Air: A Bad Fuse

Find the fuse associated with the A/C blower motor. If the blower motor fuse is still in-tact, your problem is located elsewhere. If the fuse is blown, simply replacing the fuse with an identical fuse of the same amperage rating could get your system working again!

For most furnaces, your blower motor will be located in the base of the unit next to the air filter. For most ACs and heat pumps, it will be located inside the air handler (i.e., the indoor unit). It's also possible that certain units may share a blower motor in the air handler—typically with an AC and furnace.

The most common reason why your blower motor won't work on any speed is that you have a bad or blown a fuse. A fuse is a small wire inside of a connector that is used to protect the motor itself from a surge of electricity.

An air conditioning fuse is an electrical safety device that protects the system's electrical circuit, other electrical components, and the air conditioner and its parts from damage caused by short circuits and electrical overloads. The fuse is typically located on the unit's control board.

Protection: Blower motor relay fuse is an important part of protecting blower motor relay circuit. It helps prevent problems such as electrical overloads or failures that can damage the circuit. If there is too much current or fault, the fuse will blow, interrupting the circuit to protect relays and other components.

Use voltmeter or ohmmeter to check for a blown fuse. If you find one, replace it. Start car and see if the blower motor works. If fuse blows again, check for loose circuits.

The blower motor relay is typically located in the HVAC system's electrical control panel or furnace control board. The exact location can vary depending on the specific system and its configuration. In some systems, it may be integrated into the control board, while in others, it may be a separate relay module.

In most vehicles, there are two fuse boxes—one located on the driver's side of the instrument panel and the other under the hood. Your owner's manual usually includes a comprehensive diagram of these boxes, clearly labeling each fuse.
