Angry HELP!!Headlights stay in when car is off and Cluster fuse keeps blowing

hey,

I Have s4 tII and i have a few problems.

-my headlights stay on when the car is off, hey act as if the car was in accessory mode, but in any other mode (accessory, start, on) they don't work

now im not sure if this has anything to do with it but also my clusters fuse keeps blowing (7.5W) i can't seem to see what the problem is, i've been through the wiring diagrams over and over..just don't know, even pull out the dash to see if everything was plugged in..

also my signals don't work, all i get when i try them is that clicking sound as if there burnt (i checked the there not) and nothing to the rear lights work, but im guess there is something not connected right back there.


my car runs, but im having these problems with my lights and cluster...it's a pain in the neck..i search the forum and anything that might of help, people never finished or respond on them..

Any help would be great or even more material on the wiring of my car..all i have is the Haynes manual and random stuff i find on the internet (those don't help much)

Thanks for taking the time to read this

Pull the plug off the headlight switch and put in a new Meter fuse. When you do this do you still have the blown Meter fuse and do the headlights still stay on with headlight switch off?

Headlights have noting to do with the engine running or the key beiing in the ignition.

You turn the headlight switch to ON. That puts a ground on the headlight relay in the front of the car which pulls in and makes the lights come on. Either there is a defect in the headlight harness/switch/connector or you might have a factory THEFT problem of some sort which I won't ever address.

ya when the switch to the head lights is pulled, my cluster fuse doesn't blow...now i translated all the engine bay stuff from another car, if that car had a ani-Theft module and i didn't put that in my car could that be the problem with my head lights?

So the METER fuse does not blow with the plug off the headlight sw. That's fine.

About the headlights themselves. Do they now stay off with the key OFF?

Maybe the headlight sw your using came off that other car and the other car is series?? five?

yup it was the meter 7.5W taht was going and no the other car is a s4, what if the lights i have on this car are s5 would that make a difference, cuz i got another set of relays form a na s5 last week, cuz one of the relays i had broke, (like i would shake it and i could hear peaces rattling in side it) tomorrow i'll take a video off what happens and post it up..

You have series five headlight assys on your series four car. The whole complete headlight assys with the retract motors??????

I don't see how a headlight problem can cause a Meter fuse to blow.

All you do on a series four car if you want to turn on the headlights...............is turn the **** to ON. When you do that the switch assy puts a GROUND on the headlight relay waaay up in the front of the car. That relay already has power going to it and is just looking for that ground signal from the headlight switch to pull that headlight relay in and cause the headlights to come on. No meter fuse involved in anyway at all for headlights coming on.

As far as how the retract motors work.........they depend on the Retract fuse in the engine bay and the Headlight fuse in the engine bay.........no meter fuse involved at all.

The wire leaving the METER fuse is colored black/yellow and the headlight swtich has no black/yellow wire in it. So I'm puzzled about that and why pulling that plug results in no blowing of the meter fuse. No connection that I can see there.

Headlight assys themselves use no meter fuse power whatsoever.

Usually it's the ILLUMINATION fuse that would blow if you had a bad headlight swtich or bad headlight switch harness. That's a fifteen amp fuse though.

IF the fuse blew when you put the car in reverse I could see how the 7.5a ROOM fuse could blow. But Meter fuse??/ I can't see it blowing.

I'll let someone else figure this one out

well, you seem to be right, i'm thinking that the headlights might not have anything thing to do with it, it could just be a different none retailed problem... so i tried some different stuff and found that the fuse blows regardless of anything add or removed, it always goes the second the key is turned to acc mode.. ive disconnected everything that sees power through that fuse except the cluster.. and it just blow.. no idea why...

Another problem when i turn my signals on my cpu makes a clicking sound, should it be doing that?

Something is miswires on your car and I can't tell you what 'cause I was not there when someone miswired the car.

FACT: When you go to ACC you feed power from the ignition switch to a row of fuses on the inerior fuse box. You feed the lower row of fuses where the CIGAR and AUDIO fuses are.

FACT: When you go to ACC the row of fuse with PWR STEER, ENGINE, METER, TURN, PWR WINDOW do NOT get power put on them. No power means you can't blow any of those fuses on that row.

The two facts above mean there's no reason for the METER FUSE to blow if you go to ACC alone.

The two facts above mean to me that something is miswired. I'd suggest unplugging the radioa and all associated with the radio and see if you still have the blown METER fuse problem. Most problems happen when someone wires in a radio, safc, bafc, dowadiddy bob thingamajig device and...........scew up the install.

Jpg of the interior fuse box attached. The top two rows are a batt bus and have power 24/7 as long as the BTN fuse in the engine bay is good.

The third row of fuses with the Meter, engine etc fuses is powered only if the key is put to ON or even while the key is HELD to start.

The fourth row of fuses has power if the key is to ON but loses power if the key is put to Start and Held to Start.

The fifth row of fuses is ACC and has power with the key to ON or if the key is put to ACC.

One other thing might have cause the meter fuse to blow.....but I dont see how if your in ACC. The METER fuse also powers the backup lights thru a switch on the transmission. Sooooo you might disconnect the wires to the transmission and see what happens. Although that black/yellow wire at the transmission revers switch should not have power in ACC. So this idea does not make rational sense........but something is miswired so it does not have to make sense that being the case.

Thanks big time, that give me some more ideas on stuff to look for...i'm thinking my reverse lights are just not connected to the tranny or the wire is bad..
but the radio i don't have on in the car, but i'm guessing an exposed wire some where is grounding out and makes these problems

I'll get back to you in a few days, moving my girlfriend this weekend..so wont be near the car till sunday

not the ECU, the CPU, it's right beside the fuse box inside the car
