Immediatly blowing 7.5 fuse in engine bay when i replace it. Help!
Here is my problem. All of my interior and half of my exterior lights went out last night. This morning i checked the fuses in the engine bay and found one of the 7.5 fuses to be blowin. I replaced it with a new fuse and it immediately blew it.
So what is my best option? Do i need to check every single electronic part i installed? Any advice from you guys who have been through this would be much appreciated. thanks

First question I usually ask is; what was the last thing I did to my car, and then work backwards from there.
Also since it is immediate, it's kind of a good thing, since if you have to chase wires you'll know it when you find it, as opposed to looking for something the is and intermittent short.

which 7.5 amp blew....
What's the last thing you did to the car.... chances are it's near what the short is.
If you didn't do anything, take it to the dealer, you're under waranty.
[smart *** answer] Just plug in the largest fuse you can, and look for the smoke... that's where your short is [/smart *** answer]
PS... don't do the last suggestion

i havnt done any electrical stuff in my car for a least a couple months. This happened last night, coincidently it was the first night of hard rain this year. (dont know if that connected or not)
But i do have a v1, ebc, defi unit, and other misc electrical crap in the car. Should i rip out all my panels and chase down the positive and neg wires?
BTW its the 7.5 amp fuse in the engine bay next to another 7.5amp fuse, they are labble with a little light icon on the fuse cover.

that happen to me...the all the parking light on the right side of the car is out and the lights on the climate control is out. i replace it with another fuse and it find...but u have a short somewhere...does the fuse blow even if u dont even turn on the park lights? never check for a short by putting in a higher amperage fuse.

Here is what u need to look at cause the fuse u are blowing controls the following:
Headlight Assy(position:RH), rear combination lights, a/c-ecu, heater control unit, audio unit, clock, cigarette lighter illumination light, ashtray illumination light, combination meter, hazard switch, fog lamp switch, acd mode switch, intercooler water spray switch, headlight leveling switch, generic spare connector, spare audio connector.

+1. also if you have multiple things running on the same line, a 7.5 fuse is kind of weak. Try putting a 10 or even a 15 in there and see if the problem still happens. If you don't have anything extra tapped into that fuse line, well then i don't know what to tell you

i dont think putting in a 10 and 15amp fuse will help..cause it blew even with everything turn off..so it not overloading the fuse. just like i said before..check everything u have hookup to that circuit and if everything check out ok..then u need to trace the wire and look for a short...it better to have the wiring diagram for that circuit.

This happened to me after I pulled my cd player out to run remote, and rca wires. What had happened is that the orange (dimmer signal) had 1, yes 1 strand of wire sticking 1/16" out of the casing and was grounding out on the metal behind the cd player. Cut the end off and never blew a fuse again.
