My 1999 ford RAnger has heat but the fan makes alot of noise and does not blow out the heat and the trucks gauge will go hot. What would the issue? Heater core or mayb just the fuse?

Diagnose Cooling Fan Clutch On engines with belt-driven cooling fans, a fan clutch is often used to save energy and reduce noise. The fan clutch disengages slows or disengages the engine's cooling fan when extra cooling isn't needed. The fan pulls air through the radiator and air conditioning condenser when the vehicle isn't moving fast enough to provide adequate airflow for cooling. A fan can eat up anywhere from a couple of horsepower up to 12 or 15 hp on a big V8, so by reducing the parasitic horsepower loss on the engine the fan clutch makes a noticeable difference in fuel economy

TWO TYPES OF FAN CLUTCHES basic types of fan clutches: thermal and non-thermal (also called "torque limiting Thermal fan clutches have a temperature-sensitive bimetal coil spring on the front that reacts to temperature changes. When the air coming through the radiator is hot, the spring expands and opens an internal valve that reduces clutch slippage. This causes the fan to spin faster for increased cooling. As the air cools, the spring contracts and closes the valve. This increases the amount of clutch slippage, allowing the fan to slow down and decrease cooling FAN CLUTCH OPERATION

The clutch consists of a fluid coupling filled with a silicone based oil. In the cutaway view at the left, the area between the teeth on the clutch plates is filled with silicone fluid. An internal valve opens and closes a passage between the main fluid cavity and a fluid reservoir. When the passage is open, fluid enters the clutch and makes the fan to turn faster. When the valve is shut, fluid flows back to the reservoir but doesn't return, causing the clutch to slip and the fan to turn more slowly.
The non-thermal (torque limiting) fan clutch doesn't have a temperature sensing capability. It reacts only to speed, slipping to limit maximum fan speed to about 1200 to 2200 rpm depending on the application.


A slipping fan clutch is often overlooked as the cause of an engine overheating problem.
As a fan clutch ages, fluid deterioration gradually causes an increase in slippage (about 200 rpm per year). After a number of years of service, the clutch may slip so badly that the fan can't keep up with the cooling needs of the engine and the engine overheats. At this point, replacement is often necessary.
Other signs of fan cluch failure would include any looseness in the clutch (check for fan wobble), or oil streaks radiating outward from the clutch hub.
If the clutch is binding, the fan may not release causing excessive cooling and noise, especially at highway speeds


A good clutch should offer a certain amount of resistance when spun by hand (engine off, of course!). But if the fan spins with little resistance (more than 1 to 1-1/2 turns), the fan clutch is slipping too much and needs to be replaced.
If the fan binds, does not turn or offers a lot of resistance, it has seized and also needs to be replaced.
Fan speed can also be checked with an optical tachometer, by marking one of the fan blades with chalk and using a timing light to observe speed changes, and/or listening for changes in fan noise as engine speed changes.
You should also try to wiggle the fan blades by hand. If there is any wobble in the fan, there is a bad bearing in the fan clutch, or a worn bearing on the water pump shaft. A bad water pump bearing will usually cause the water pump to leak and/or make noise, but not always. Remove the fan clutch and see if the play is in the water pump shaft. If it feels tight (no play or wobble), replace the fan clutch.


Many experts say it is a good idea to replace the fan clutch at the same time as the water pump if the water pump has failed. The reason is because both age at about the same rate, so if the water pump has failed, the fan clutch may also fail soon. As as we mentioned earlier, a high mileage fan clutch may be slipping excessively increasing the risk of overheating.
When you buy a replacement fan clutch, make sure you get the same type (thermal or nonthermal) as the original. You can always upgrade from a nonthermal to a more efficient thermal fan clutch, but never the reverse. Or, you can get rid of the fan and clutch altogether and install an aftermarket electric fan kit to cool the radiator.

How to troubleshoot an electrical brownout (computers)

<p>Modem router and switches <br /> <p>1. Plug the device into the outlet and see all the lights. Determine if they are all about how they should turn. <br /> <p><br /> <p>2. Disconnect the device from the device and allow to rest for five to 10 minutes you can Sun <br /> <p><br /> <p>3. Turn off the lights of the device into an outlet and a view of the screen to see where we are going. When you're gone, then the Brownout the unit is damaged and needs replacement. <br /> <p><br /> <p>Computer <br /> <p>1. Disconnect the computer from the electrical outlet and turn it so your back is turned. <br /> <p><br /> <p>2. Locate the AC adapter to the top of the PC, the rear fan. Near the fan and see if a burning smell. <br /> <p><br /> <p>3. Connect the power cable from the PC and turn on the computer. Hear the sound of the computer. If you do not hear and determine that there is a smell of burnt food, replace the power supply. <br /> <p><br /> <p>4. Open programs and working on the computer. Look to see that the freezing tissue damage your computer or network restart. <br /> <p><br /> <p>5. Listen to the fans to operate. If not the fan or the hard disc, that harm could be caused by a voltage drop. <br /> <p><br /> <p>6. Open your Internet browser and try online. If your computer is not connected to the Internet, and you're using a wired connection, unplug your computer and check the NIC light to see when it flashes. A light no flashing is an indication of a failed network card. Check the lights on the modem, router, switch and hub. If all lights are working, but the computer will not connect to the Internet, this means that the board brownouts wireless network or affected. You must replace the device failed. <br />

Fan continually runs at a high speed

There are a couple of things here. I am assuming you mean the cpu fan. Not sure if there is a vga fan. And the power supply, well, you have no choice here. Anyway, make sure the inside of the computer is lint free. If the heat sink is dirty (under the fan), then dissipating heat is a problem. Heat triggers the fan based on the tolerance temperatures set in the bios of the box...normally accessed via F2 or F12 on bootup. Yes you can increase those temps but this is overheating can cause instability and hardware failure.

Electric cooling fan bearing failed and the cooling fan needs to be replaced. Start with inspecting the cooling fan behind the radiator and determine if that is where the noise is coming from. Replace any worn or damaged parts.

the fan has (maybe - check it) a filter screen between it and the outside air... cleaning this filter will increase airflow. cooling fans are really cheap and its a good idea to replace a fan that has had a hard job in a hot environment BEFORE it fails...
sorry, I dont know how to open the door though... maybe you'll have to take the entire case off... then you'll see how the door comes off for next time anyway - if you're "servicing" the set you could do worse than get the case off and clear the dust out.

My hard drive has been making a clicking noise for a while, the computer freezes up at times, I do not think the cooling fan is working, could this cause the issue with the hard drive making noise, and if...

More than likely, your hard drive is failing. This COULD be the cause for the freezing. The other thing that could cause the freezing is if the processor is getting too hot due to the failed fan. Either way you will need to have your HD replaced before it fails completely. The clicking you are hearing is the read head hitting the case of the hard drive. It might have started from being too hot. If the parts of your computer are getting too hot, it will increase the chances that they will fail in the future.

My trailblazer (2002) was making allot of noise as i gave it gas.

should have the coolant temp sensor replace from the sound of it. if bad it will think it is cold and dump more gas to keep it running. it also runs the fans
