What fuse goes to the blower motor?
Fuse Protection To protect the blower motor power circuit, a 20-, 25- or 30-amp fuse is usually located in the fuse panel under the dash. The rating of the fuse will depend on the vehicle application and how much power the blower motor requires at full speed.
How do I know if my blower relay is bad?
If you have a faulty blower motor, you may experience low airflow from the vents, even when the fan is on high. There will be no air coming from the vents if your fan isn’t working due to a bad blower motor resistor.
Why is my blower fan not working properly?
Hi check the fan resistor as they get covered in dust and crap and the little coils rust and break it’s likely to be the problem. Take the clovebox out and it’s right in front of you. Thanks mate, think I will pull the fan motor out and test it as I have checked the fuses and it won’t go on any speed. Could it be in the fan speed switch?
When do I need to replace the blower fan?
The test light should light up on each and every speed, if it does then the fan motor needs replacing. If it lights up on only the high speed then the fan motor and resistor need replacing.
Is the blower fan OK on a gu 4×4?
If you can hear/feel the interior fan working on all speeds then the resistor and motor are ok. If you have a GQ then this is more then likely your problem. Nah it’s a gu 4. Might have some crap in it. It’s pretty noisy. 12v to the fan moter so i gave the fan a tap with my screwdriver handle and it started to work.
Where is the blower fan relay on a Nissan Patrol?
The wiring diagram I have shows the blower fan relay mounted in the same block as the fuse box inside the vehicle. There are 3 relays above the fuses and it is the one in the middle right at the top.
What causes a fuse to blow on a blower motor?
If the blower motor relay develops any sort of problem that hinders its ability to properly limit and distribute power, it may cause the blower motor fuse to blow. Any sort of electrical spikes or excessive current from a bad relay will blow the fuse and cut power in order to protect the system.
What causes a bad or failing blower motor relay?
Blown fuses. One of the first symptoms of a bad or failing AC blower motor relay is a blown AC blower motor relay circuit fuse. If the blower motor relay develops any sort of problem that hinders its ability to properly limit and distribute power, it may cause the blower motor fuse to blow. Any sort of electrical spikes or excessive current…
What happens if you have a bad blower motor?
The blower motor is the component responsible for pushing air through the vents of your vehicle’s heating and air conditioning systems. Without it, the AC system will not be able to circulate any heated or cooled air.
Where is the blower control switch on the dashboard?
The blower control switch on the dashboard controls the circuit flow of the blower motor to adjust the voltage from low, to medium, to medium-high, to high. When on high, the circuit bypasses the blower resistor.
