Was the van in for repairs recently? Have you looked around the engine compartment at all? There are several harnesses that wrap around the engine. It's possible one of them is soaked with oil (or not) and has shorted against the block. You don't want to waist too many fuses trying to find the short. I recommend a short finder tool to locate the source. If you don't have this tool a test light will work but it will take longer. Clamp the light's lead to battery power and connect the probing side to the fuse terminal (leading to the short). Wiggle each section of each harness until you see the test light flicker of go out. This should help put you in the right direct or the source. Let me know if this helped or if there is anything else. Good luck.

SOURCE: 2002 Dodge Neon 20 amp FP/ASD fuse #21 keeps blowing

It appears that it is part of the fuel pump circuit, so I would concentrate on wiring harness & connector at fuel pump, clean it real good, and apply dielectric grease to the connection, as well as the fuel pump relay, connector & harness.

SOURCE: 20 amp ignition fuse keeps blowing

I'm curious, does this vehicle have an alarm/remote starter? If so I expect the installer didn't wire it correctly ... it was an all too frequent issue, with inexperienced installers we had .... I would first suspect any add-on device first (if any) ... In answer to your question ... I know it does have a relay (Starter solenoid is a relay and built onto the starter) As far as it being a relay or the IGN switch ... I'm skeptical.

SOURCE: Wiper fuse keeps blowing intermittently.

It looks like the wire circuit for the wiper motor is touching the car body when shaken so the only thing you can do is shake the wires and terminals yourself while engine is running then maybe you can pinpoint where the earthing is.

hmm. lt look like there are poor joints in your wiring specially the groung wire. check the diagram of your auto. check the unit diagram for which the fuse blows. usually the fuse blow when there is a short circuit. if you look around you will find it.
good luck

SOURCE: am2 30 amp fuse blowing

check the battery cables for wear and make sure they aren't grounding out on the frame you have a direct short and that is more than likely where it is

20 amp ignition fuse keeps blowing on my 2003 dodge stratus


SOunds like a closed short in the ignition system. The actual ignition could be at fault. The starter may be at fault. Pinched or exposed wiring touching the chassis or another live wire may be the cause. Check your manual to be sure the 20 amp fuse is the proper fuse for the ignition system. It may just be to low of an amp and may be a 25 to 60 amp fuse or more. Only use the recommended size of fuse as using too high a amperage in a fuse can cause bigger problems if the fuse does not blow in time. These fuses serve a purpose to save the electrical and electronic parts form unnecessary damage.

2002 chrysler sebring fuse keeps blowing for ignition wont start untill you replace fuse. what amp fuse should be in it. or what could be causeing it??


For your ignition you should use a 20-30 amp fuse. However, it sounds like you have a short somewhere. If you have a short it is not going to matter how big of a fuse you use it will keep blowing out. You best bet would be to take your car into the shop and tell them you have a short and to find and fix it. I must warn you though, shorts are very often times very hard to find, and take alot of time to find. Therefore most of the time they are expensive to fix. I know that probably was not what you wanted to here, But I hope it gives you a place to start out at. Hopefully this helps you out.
