Why the 30 amp fuse under hood for heater fan keeps blowing

If it blows immediately after turning the fan on, there must be a short. If it takes a few seconds, the motor could need to be oiled, unrestricted (if something is stopping the squirrel-cage from turning), or possibly replaced. Don't go with a larger fuse; you'll burn up the wiring.

Why is my instrument 10 amp fuse under hood of my 2005 Kia sedona blowing

The fuse is used by the following :
1. PCM.
2. ACC.
3. Trip computer.
4. Stop Lights.
5. DRL.
7. Instrument cluster.
8. Front heater and A/C.

Any of the components could be the cause of it. Note if the fuse blows when any component relaed to it is operated, such as blower fan, applying the brakes.
PCM and trip computer would be less likely to be the cause as they uses minimal current.

Try this first. Replace the fuse. Make sure the AC & Heaters are OFF. Start your vehicle and sit there with the car running. Turn on the heater on full blast and wait. Tolerate the heat. If the fuse blows again, you have a problem with your heater circuit (fan or heater switch). If it does not blow, turn the heat off then turn on the air conditioner full blast. Tolerate the cold. If the fuse blows your problem is with the AC circuitry. If nothing blows. Turn off the heat and the air conditioning. Step on the brakes and hold it down for about 10 minutes. If the fuse pops then you have a problem with your brake light circuit (brake light bulbs may be shorted, your brake light switch may be bad, etc.). These are the easy checks. After that you need to take your vehicle into a shop that can troubleshoot electrical problems. Sorry, but that is about all you can do at this point. They will be able to tell you exactly where the problem is. However, you need to take it to a place that is experienced in troubleshooting car electronics.

My GMC Envoy keeps blowing the 10 amp fuse for the heaters.I unplugged the front blower fan but it still does it. Is the other fan in the consul?

The fuse isn't for blower motor. I saw a fuse 39 and fuse 36 both 10 amp, both for hvac. I don't know which one is blowing? One fuse is for actuator doors under the dash, the other is battery voltage to hvac control module. One is hot all the time, the other goes hot with key on.
What is model year? Does it blow as soon as you turn on the key? Any applicable hvac trouble codes? About all I can do is track wiring circuits.

2004 Ford Ranger 10 amp fuse keeps blowing no brake lights,abs, turn signals?

Fuses blow because there is an overload on the system. If the fuse blows when you step on the brakes then there may be a short in the wiring from the brake light switch to the lights, abs module or turn signal switch. If the fuse blows when you turn the key on then there is likely a short in the wiring to the brake light switch. Basically you will need a wiring schematic to check the wires at the switch and at each of the loads. Also verify that the fuse is supposed to be a 10 amp fuse. Hope this helps

The 10 amp fuse that goes to the turn signals and heater fan keeps blowing on my 1997 dodge caravan

That fuse circuit goes hot with the key on, shouldn't have voltage before you turn the key on. The fuse circuit sends voltage to several circuits, one of which is the front blower relay. Unplug the relay, see if fuse still blows? If you need to enlarge diagram, sometimes you can click on your highlited post, on that page you may be able to enlarge diagram.

2002 tracker,keeps blowing 15 amp fuse that runs heatr fan and lets car shift out of park

I looked at the wiring diagrams and those two circuits should be on two different fuses.
The shift lock solenoid is powered by the 10amp turn signal fuse and the 15amp stop light fuse. If the fuse blows when you put it in park, I would say the shift lock solenoid is the problem and the stop light fuse is the one that is blowing.
The heater fan and relay are powered by a 60amp fuse and a 15amp fuse but not the stop light fuse.
Its possible there is a short some where that has connected these two circuits.
You could disconnect the shift lock solenoid to see if the fuse still blows.

1999 Chevy Malibu 3.1 v6 the car is overheating during idle i replaced the water pump because it went bad but is still overheating. The cooling fans are not kicking on at all any ideas why? Also the turn...

what turns the fans on is the ECM and it does that by energizing a relay for the fans
that signal to the ECM to turn the fans on comes from the coolant temperature sensor unit in the coolant system
so check the fuses (2) , check the sensor , check the relay and then check that the fans will turn if they get power as for the fuse problem , the fuse should be around 5 amps but to aware that if the fuse in use is too high a capacity , then the harness will burn with a possible result of a car fire
take it to an accredited auto electrician to check the circuit out

Air condition

Check the following fuses:
10 amp GAUGE under the dash, and the 40 amp HEATER under the hood.
If both fuses are good, I suspect that you may either have a bad fan switch or a bad heater fan motor. The switches are rare to fail, I would suspect the heater motor first. Please try this: Turn the key on; turn the fan switch to high. Look under & behind the glovebox, for the bottom of the heater fan motor. Round thing with 3 screws holding it to the heater box. Using a small hammer, or something that you can tap with, tap on the bottom of the heater fan motor. You just may jar the motor enough to make it run. If it comes back on, you may need to replace it at some point in the near future. Worked for me quite a few times. Try that, repost to me what happens. Hope this helps.
