There is a little black fan on the front of my engine that runs more than normal. Twice now it has drained my battery. The only thing I have done is pull fuse #7 to cut the power. Although this is a quik fix I would really like to know what the fan is/does and how to fix or troublshoot it.

Re: Fuse # 7 (Fan)
4cyl or 6cyl engine? Have the cooling fan switch checked. It is supposed to go on when certain temp is reached, but it apparently isn't functioning properly if it isn't turning the fan off when the temp drops.

the problem with pulling the fuse for your fan is that your fan wont come on anymore therefore it won't cool the engine and your engine will probably overheat and that is a very dangerous thing for the motor. A temporary fix would be to pull the fuse and put in a toggle switch then you could turn the fan on and off manually. You need a toggle switch that flips on and off only. There are two connections for the toggle switch. Connect two wires to the toggle switch and run one wire to one side of the fuse and the other wire to the other side of the fuse in place of the fuse itself.

"2004 Suzuki air which is fan relay which is located"
i translated it for you.
which fan, the engine Radiator fan or the passenger cooling /heating fan. there are 3 fan systems, heater blower, RAD and A/C condensor
so? ill guess RAD or A/C
ill answer for, RAD fan relay, old post
it's the relay in the PDC, marked FAN. (if car is English car !)
fuse 23, but that runs many other things besides fan.
relay 1 runs the fans.
now A/C fan at the condensor way out front.
Fuse 12, and again runs many things.
fuse box 1, next to battery has 2 relays, #1 fan #2 fan for RAD
the condenser fan and compressor relays, right there same place.
The fan is only supposed to come on when there is excess heat .. in normal driving conditions it doesn't start. When you start your car in the morning the fan won't come on because the engine is cold.
With a hot engine - and it depends how hot the engine is - the fan will only kick in to prevent overheating. In heavy slow moving traffic or a traffic jam, the fan will kick in if needed.
The air flow through the radiator is usually sufficient -in normal driving conditions - to cool the engine.
When you park up and the car has a hot engine, the fan will kick in. This is perfectly normal. It is caused by a surge of hot coolant triggering the fan sensor. Perfectly normal.
The fan then should cut out after a while .. maybe 2-3 minutes at the most. If the fan runs continuously that suggests a fault in the temperature sensor switch.
Next time - wait by the car and see how long it takes for the fan to quit after you have parked up. It should stop of its own accord after a couple of minutes.
If the fan cuts off after a short while, and your battery is becoming drained, that's probably a battery or alternator fault.
Remember: when you start the car the fan won't kick in at idle speed because the engine is COLD, and there is no reason for the fan to start up ..
The fan WILL kick in for a couple of minutes after you have parked the vehicle and the engine is hot
my battery drain indicator lamp is lit on my 2000 Toyota Camary. i checked the battery and have 12.5 volts when not running and 14.5 volts when running with lights & heater on. since all my other gauges are working ok i'm not sure if its a fuse or what fuse. can you help. altenator shows 14.5 volts when running.
94 Metros have a 'hidden' fuse in the power lead to the radiator's fan. There's a good chance it's blown. Look under the dashboard near the fusebox, but behind it (toward the firewall) in a completely separate fuse receptacle (not connected to the main fusebox). It should have a whitish color and a small plastic snap-on cap. Under the cap is a standard 30AMP fuse.
If that fuse isn't blown, then it might be the temperature sensor. You can test that by bridging the two wires that go to the sensor; if the fan comes on, the sensor is bad -MAKE ABSOLUTELY SURE YOU HAVE THE RIGHT SENSOR FIRST!!!!
Lastly, if all else fails, it might be the fan solenoid which is a little black box located under the hood near the main fuse block. You'll need a wiring diagram or a little know-how to test it.
to check the radiator fan you can look in the fuse box area and find the fan relay, pull that black relay and if the fan stops thats what it is. if it doesnt then its something else but probably the fan and should be electronically diagnosed, atleast you can check to see if it is that by pulling that fuse according to the diagram on the relay cover underside.
It's possible that the fan control relay is intermittently sticking causing the fans to run continuously. This can overheat and subsequently blow the fuse. Try replacing the relay and see if anything changes.
