Need help with my 03 Acura TL

Other day I'm driving home and my instument pannel goes dead, all gauges. Check battery, its fine, check the fuse for the dash and its blown, go out and replace the fuse, turn the car on, dash works but engine malfunction light is on and airbags are off. Get about halfway home and the instument pannel dies when i go over a big bump (after like 5 minutes of driving). Get home, replace the fuse again, this time nothing happens? Anyone have any ideas?
 
It sounds to me like a wiring harness under the dash has either come loose or the wiring is rubbing the
metal chassis and shorting out, blowing the fuse. A careful look should turn up something. Or possibly
the engine computer is bad, as a lot of cars drive the instruments thru the engine computer circuits.

Was the fuse blown again?

If so, you've got an ugly problem. Tracing circuits in a modern car is time consuming and/or expensive, to say nothing about the price of the wiring harness the dealer is going to want to put in.

I'd start having a OBD codes read. Maybe it will point at something.
 
If the fuse is blowing, there's probably a short somewhere. Have fun.

For these sorts of automotive problems, I usually recommend alcohol in large amounts.

This.

Unfortunately.
 
That is what I figured. Fuckin eh. I just wanted a second opinion before I fully realize that I hate my life.
 
Yeah, you're probably going to have to get under that dash and start looking for bare wires or wires with cracked insulation or maybe a ground that has come loose. It's not gonna be easy though.
One easy thing to check first would be all the under hood fuses and the other fuses in the fuse panel. If another fuse wired in paralell melted but didn't blow that could be causing the problem. However from what you described after going over the bump and the fuse popping again, that sounds like a shorted wire.
 
Yea this morning I went out to get something from my car and just for the shit of it I jiggled a bunch of wires around and put a new fuse it. Before the fuses were blowing immediatly, but this time the dash came right up. Weird shit. Oh well its due into the dealership tommorow at 7. Any reason I shouldn't be driving it (just to work, which is 5 minutes away)?
 
You should be OK, that is why they make fuses, as long as you don't overfuse it.

Reminds me of the two good ole boys out in their pickup poaching deer one night. All of a sudden their headlights went out, and after basic trouble shooting they found out the headlight fuse was blown. With no extra fuses, one of the rocket scientists figured out he could use a .22 cal. round laying on the floor as a substitute. Everything was fine for about 5 minutes and all of a sudden the round went off hitting the driver in the the nuts......no one died.

That story was just an urban myth, although it was based somewhat on a true story which involved the driver getting shot in the knee.

996GT2, totally urban myth, but humorous none the less

Moral of the story?.....Don't over fuse your electrical system

No?
