I think my multiplexor blew? (problem fixed)

Re: I think my multiplexor blew?

Unless you are willing to risk electrical damage or a fire. A fuse is a protection device that is designed to blow if the amp load in a circuit exceeds the "safe" limit for that circuit. When the current in a circuit exceeds the normal limit for whatever reason, the metal element in the fuse melts and opens the circuit stopping the flow of current. A short, for example, causes a runaway electrical current. If not stopped, wires can start to melt and things can catch on fire.

Under no circumstances should you ever bypass or eliminate a fuse. No electrical circuit should ever be operated without fuse protection. This is extremely dangerous, especially if you've had problems with a fuse blowing before.

^^ Yep. You NEVER want use bigger fuses than specified. I once overheard the guys at the local autozone told a customer to use bigger fuses...idiots.

It just blew out randomly yesterday on the freeway. like i've stated i did not do any electrical work for over 1 year and it just so happened very randomly. i put in a new 10 fuse and i turned on the parking light and the fuse just blew after being on for 10 seconds. I am going to retrace all the wire hacking I did years before to double check connections and make sure no wires are exposed and touching metal.

My buddy's 240 was doing the same thing, turns out it was the turn signal wires. They were bare and rubbing on the chassis so every time he turned his lights on the fuse would blow. So if I was you I would check the wiring to your your fogs, headlights, turn signals, and taillights.

The dumbest thing to ever do is bypass a fuse, like sticking a penny in there. The second dumbest would be upgrading it of course. lol

But a short could be anywhere in the wiring where the problem area is honestly. They can show up just from a spot being rubbed against due to vibration or just not being secured properly, and it's rubbed the insulation off of the wire. They can also be due to wires falling loose from a connector, or a joint coming loose. Also if you've ever ghetto rigged any joint by insulating it with electrical tape, the tape will unravel , it's just a matter of when.

Do you have a multimeter?

Guess im a idiot then . My cars been fine . I put a 15 where a 10 is. Not like im putting a 45 in where a 5 goes

unfortunately, nope. over the weekend i will go back to some wiring i did years ago and double check the electrical tape. ty for your help.

A little change like that probably won't hurt anything, but it is never an appropriate fix. It might "get you by" but you didnt actually fix the problem. Upgrading fuses is just a habit that should be avoided, because it might come back to bite you.

I hope you find the problem. Troubleshooting a circuit can be a pita sometimes.
You should pick up a multimeter, iirc you can get them for a decent price at Harbor Freight.

Re: I think my multiplexor blew?

O crap, I did swap out the bulbs at the bottom of the doors for some cheap ebay led bulbs two-three days ago.... That might be the problem...... I guess I got for what I paid for.... Hope swapping it back to oem will fix the problem.

Re: I think my multiplexor blew?

Well you don't necessarily need to swap back to filament bulbs, just some that were made properly. ...if that is the case.
It sounds weird that just door bulbs could do this, but you never know. The problem arising at the same time you put the new bulbs in makes it sound pretty likely. Let us know what happens.
