If you had a 5 amp fuse and fan draws 3 amps all is good.
BUT, if there is a short circuit before the fan, it will blow the fuse.
Check the wiring is not chaffed or worn between fuse box and fan, or switch to fan.
Fuses blow because of higher than normal amperage in the circuit. Not sure what circuit the blown fuse is for but if it is for the fan the fan may be shorted therefore blowing the fuse. If you put fuse in while the ac was still on try shutting off the ac then putting the fuse in. See if it blows then if it doesn't then turn the ac on and if it blows you have at the very least isolated the system at fault.
HACK! the radiator relay is probably bad, located down near radiator left lower corner,bolted to frame,have to get at it from underneath. Be sure fuse #24 (40 amp) is good. A scanner should activate the fan if the relay is good, if not its probably bad, Make sure the fan does not pull more than 20 amps when running, if it does, that could have burned up the relay.
thats normal,,, the motor is likley to have a shorted coial in it, if sit will pull far more amp's that is should and it blows the fuses, dont try fitting a biger fuse in,,,,,,you will just start a fire in the car!
Several things ... best guess, in order: 1. (very likely) Radiator fan is not blowing (turn on car and a/conditioner.
When compressor kicks in, the radiator fan must blow). If it ims not blowing,
the radiator fan motor may be burned out ($40). 2. Check / replace "cooling fan" fuse ($1) and / or "cooling fan" relay switch
($7). 3. Could be (not likely) thermostat sticking shut. Replace thermostat ($20) 4. Could be radiator hose collapse (not very likely) ($18) 5. Radiator clog or hose leak (possible) 6. Head gasket broken (not likely unless you don't fix current problem) ($150)
The more detail of the symptoms, the better we can assist you.
Hope this helps!
Blown fuse means there is an increase of current due to an increase of load or a short. You may want to check the wiring harness that has the wires of those not running that you have mentioned for open circuit, corroded insulation, loose cable, ect that needs replacement and mending.
If your cooling fan is not working you solved your own problem. The cooling fan is what helps your radiator perform its function. The radiator cools down the antifreeze mixture by separating it into small tubes separated by air fins, the fins allow a greater surface area for air. The radiators main function is to dissipate heat into the surrounding atmosphere which it can do well at highway speeds without a fan, but most modern cars need a cooling fan to help pull air across the radiator.
The wiring diagram for your vehicle suggests that there is a 5 amp fuse 4 and a 40 amp fuse 42 that run the radiator fan and control which should be located in an under hood fuse/relay box. Check them with a test light on both sides, with the light to ground you should see a positive voltage at both sides. the 40 amp would most likely be a maxi fuse, or a larger size then the regular atm fuse for the 5 amp,
Make sure you have 50/50 mix antifreeze, it will still run hot if you have 100% antifreeze. As the antifreeze get's hot, it turns in to gel and the flow slows down and the heat exchange will be reduced. Water is great in transferringheat but it will boil over so antifreeze is added to keep it from boiling over, so a 50/50 (water/antifreeze) mix is used. You can go a bit higher with the antifreeze but try not too and in the winter you can go 40/60 (water/antifreeze) if your in really cold climate area. The other thing to is do you have electric radiator fans?? Think you do, make sure it's working. When you turn on your A/C the radiator fan should come one and also when the temperature gauge hits 180 - 195 degrees the fan should come on too. If not check the fuse, relay's and wire harness to the fan. Good luck and hope this helps.
The fan may run with jumper wires but if it''s blowing the 30 Amp Maxifuse it's needs a new or used fan motor.It's pulling too many amps.I have almost never seen a fan relay concern.Only other thing you may check is the wiring down near the fan shoud I have seen the 2 wires get loose from the conduit & melt onto exhaust manifold.Hope tHis Helps
