Car Ac Cooling Fan Not Turning On

Broken or shorter signal wire.

Car ac cooling fan not turning on.

The engine of a vehicle has a combustion chamber where continuous explosions take place and as such the engine heats up very quickly. To stop the engine from overheating we take the help of coolants that flow through a radiator into the engine. Blower still does not work. Automotive air conditioning system uses an electromagnetic clutch mechanism that engages the compressor to turn the ac unit.

As for the engine coolant temp sensor if the coolant is not hot enough to make the fan come on then there is no need for the fan yet and there is no problem.
