Why is my instrument 10 amp fuse under hood of my 2005 Kia sedona
The fuse is used by the following :
3. Trip computer.
4. Stop Lights.
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.
