Can a bad fan motor cause a breaker to blow?

CAUTION: If the fan fuse or fusible link is blown, or the breaker has been triggered, it is possible the fan motor itself may be bad and causing the fuses to blow. Replace the fuse or fusible link, or reset the breaker, and test the fan motor again. If the same problem appears and there’s no wire causing a short circuit, replace the fan motor.

How can I tell if my radiator fan is working?

When a radiator fan works it usually makes a whirring sound that is easily noticeable. However, the radiator fan does not always start spinning on ignition.

Why are the fans not working on my MkIV?

Why are the fans on my car not working?

It melts and this particular part sends power to the cooling fan thermal switch AND the Fan control module. The fan module also sends power to the a/c compressor. So pretty much the fans don’t work and your a/c blows warm. Check this first before checking other areas.

What to do if your a / C fan is not working?

The a/c button turns the fans on LOW only, and the fans will still work on high if the engine temperature gets too hot, above 107C actually, or 224F. The only way to fix this is to replace the defective fan.

What happens if your radiator fan is not working?

A radiator fan is important as it helps to circulate air within the engine of your vehicle and keep the engine temperature down. If the fan isn’t working, it could lead to overheating and cause damage to the engine which could prove very costly.

What are the symptoms of a bad thermo coolant fan switch?

Several symptoms may point to a bad or failing thermo coolant fan switch. 1. Engine overheating Engines generate an enormous amount of heat and as a result are subjected to very large temperature swings if this switch does not operate effectively.

When to turn on the coolant fan switch?

As engine temperature rises to a specific threshold, the switch is activated powering on the coolant fan. The coolant fan will continue to run until the engine temperature cools down to a specific predetermined level.
