If the fan doesn't work, before pointing the finger at the blower motor, check fuses for the motor to make sure they're still good. 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.
Yes, a blown fuse can cause a car heater not to work. The car's heating system relies on various electrical components, including the blower motor, which circulates air through the heater core.
You need to use a multimeter and check for continuity from end to end of each fuse. If you have continuity, it's good. If it's open/no continuity, it's bad.
Ac clutch is fuse 25 and is a 10 amp fuse. Blower motor is fuse 35 and is a 40 amp. You could test them with a meter or visually look to see if they're blown, then take it to a shop if they blow after replacing them.
Either it's not getting electrical power or, more likely, the motor itself has simply burned out. A blower motor in an older vehicle is likely to burn out over time, and may need replacement.
Electrical Issues: Circuit Breakers, Fuses, and Wiring Problems. Within a furnace system, electrical problems and circuit issues rank among the most common causes of fan failure.
In many modern cars, electricity even powers the A/C's compressor. So, if one of those fuses blows, you may experience other issues, like weak airflow, warm air, and poor ventilation. If you notice any of these signs, it's possible that a blown A/C fuse is to blame.
Engine fuse boxes are typically situated near the battery. In this vehicle, the battery is on the driver's side, and there is a fuse box right above it with a black plastic cover to protect the fuses. On the passenger side, there is also a battery, and the fuse box is located nearby.
The average cost for a Blower Motor Replacement is between $342 and $362. Labor costs are estimated between $68 and $86 while parts are priced between $274 and $276. This range does not include taxes and fees, and does not factor in your unique location. Related repairs may also be needed.
The blower motor is responsible for circulating the air through the AC system. If the blower motor is not working, the air will not be circulated properly, which will cause warm air to be blown into your car.
This could happen for a wide variety of reasons, such as a faulty wire, broken switch, or blown fuse. Another common reason is your compressor not turning on because it doesn't have enough refrigerant. Most compressors won't turn on if they go below a certain refrigerant level.
Strange Rattling, Clanking, or Screeching
One of the first signs you may notice when there's an issue with the blower motor is a strange noise coming from the indoor unit or air handler.
Step 1: Prepare the vehicle
Start by disconnecting the negative battery terminal, and set it aside someplace where it isn't touching metal. If applicable, remove the passenger-side floor mat. Typically there is a plastic cover underneath your glove box.
Air conditioners can stop working if there is a blown fuse. Replacing that fuse can fix the problem, though it's important to have a certified car AC service technician check your electrical system.
To check fuses and see if there are any easy-to-reach short circuits: Remove a fuse at random and connect your test light to the terminals for the fuse socket (the place where the fuse connects to the electrical system). The test light will light up if an electrical current is detected.
Luckily, AutoZone provides you with top-quality fuses, fusible links and circuit breakers at the best price on the market. Fuses and circuit breakers vary depending on your vehicle's year, make and model.
In most newer systems, the button is often directly next to the blower motor, while in older systems, it may be harder to spot as it is sometimes underneath or behind the motor. The reset button is often made of yellow or red plastic and marked with a large “R ” to make it easier to spot.
The thermostat is what tells these separate systems to work together. In normal operation, when your thermostat is set to "auto," it will tell the blower fan plus the heating or cooling components to turn on and off at the same time when the desired temperature is reached.
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.
You can reasonably expect to find replacement blower motors at Parts Geek from $20 to $120, while the majority of these motors cost between $190 - $275 when you buy them from other parts stores. Costs for this part depend on several factors: Compactness of design. Levels of blower precision.
