Where is radiator fan fuse on 2007 chevy silverado?

Deanna, check to see if your A/C is in the on position, this could cause fan to run a lot. If this is not the case, take truck in for diagnoses at a good shop, could be a faulty heat/fan sensor or sticking relay. Check the attached links,instruction and guides, Good luck

It depends if it is a classic or new style Silverado. Both were made in 2007. If it is a classic Silveradothere is a replaceable relay in the under hood fuse block. If it is a new style Silverado the horn relay is part of the printed circuit board that is only available with UBEC (under hood bussed electrical center).

Gasoline Engines

1. Drain the cooling system.
2. Unfasten the upper fan shroud bolts and remove the upper fan shroud.
3. If equipped, remove the upper panel fasteners and the panel.
4. If equipped, remove the upper insulators and brackets.
5. Disconnect the radiator upper and lower hoses and, if applicable, the transmission coolant lines.
6. Remove the coolant recovery system line, if so equipped.
7. Remove the oil coolant lines, if equipped.
8. Remove the lower fan shroud bolts and the lower fan shroud.
9. Remove radiator from the lower brackets and insulators.

If your missing or have cut off & destroyed wiring,
you will obviously need a wiring diagram to repair
that part & restore things as the vehicle was built,
so you just mount the new fans & plug in

This sounds like a bad coolant temp sensor that give computer false reading, check the coolant temp sensor connector and if it is good with no bad wires to connector then replace coolant temp sensor , when the computer gets a signal from temp sensor that engine is hot it turns fans on high speed to cool radiator and displays a/c turned off , if this truck does not have electric cooling fans then they wont run just explaining what happens depending on engine and cooling set up. replace coolant temp sensor and check connector.

It is at the bottom driver side corner an inch or two up. It is plastic and hard to open. Can be stripped very easy. I just replaced my radiator with an all aluminum unit from BeCool because of this. Will never use another plastic radiator again if I can help it!

sounds like you have a bad temperature sensor/fan switch usaully located on the radiator. turns on fan when coolant reaches operating temperature. when moving the ram air going thru radiator is enough to cool the engine without the fan,

The bower motor is most likely what you are smelling.Replace the blower motor,and the blower resister next to the blower motor if,the blower motor has no speeds.

try checking the hoses for blockage,and if not that make sure the fan is working right as it might be the fan cluch,or your water pump may have went out,best of luck
