Honda Odyssey 2004 has not got fan belt. It has got 3 ( three ) belts - timing, power steering and alternator A/C belt.
Sounds like you need to replace your blower motor resistor.
The cooling fan relay is in the fuse block under the hood on passager side
Very carefully
You cant replace it, it's all in one piece.
To fix a noisy bathroom fan, you can try cleaning the fan blades and housing to remove any dust or debris that may be causing the noise. You can also check if the fan is properly secured to the ceiling or wall, as loose mounting can cause vibrations and noise. If these steps do not resolve the issue, you may need to replace the fan motor or the entire fan unit.
The heater in the CRV Honda is not working . How do I fix this
Not enough info - which fan? The passenger cabin blower fan, or the engine radiator cooling fan?
It sounds like your blower fan resistor is not working correctly. Eventually it will stop working all together. I suggest that you get a replacement.
theres no fan belt on front wheel drive motors. only a fan motor
Your bathroom fan may be noisy due to a build-up of dust and debris, a loose fan blade, or a worn-out motor. Regular cleaning and maintenance can help reduce the noise level of your fan.
To reduce noise from a noisy fan, you can try cleaning the fan blades, tightening any loose screws, placing rubber pads between the fan and its mounting surface, or replacing the fan with a quieter model.
