Electrical switch in steering post .reset 3x Lost head lights and directional lights Looking for electrical diagram with pictures for this problem. Subaru legacy wagon 1991 Thank you

Did you view wiring diagrams then test the electrical circuit's using a DVOM - digital volt ohmmeter ? Looking at factory service repair info. , reading how the headlamp's work - battery voltage supply & ground circuits an testing . Going to ALLDATAdiy com Leading Source of Factory Automotive Repair Information , an buy a year service repair info. for your vehicle . Then learn how to test automotive electrical systems .

The Trainer 29 Understanding How Electrical CIrcuits Work and How to Test...


This is how a professional technician does it .

Without testing we'd only be guessing . You need to look at a wiring diagram to see what all is involved in making the head lamps work . Then using a DVOM - digital volt ohm meter to test for B+ voltage in different parts of the headlamp electrical circuit's till the problem is found. Looking at the wiring diagram for the head lamps on your vehicle I see a lot of thing's that could have gone bad , one being the Light control module (electronic's) , Plus the headlamp / park lamp switch , headlamp dimmer switch , twilight sentinel control etc...... Your best bet , take it to a qualified repair shop , unless you know how to diagnose automotive electrical systems . Free wiring diagrams here http://www.bbbind.com/free-tsb Enter vehicle info. Year , make , model an engine . Under system click on lighting , then under subsystem click on headlamp's . Click the search button then the blue link's . Let me know if you think you can decipher what the diagram is showing .

Yea , an what would you like to know ? You have a direct short to ground on that circuit . Looking at a electrical distribution diagram to see what all that fuse powers should be your first step . Do you know how to trouble shoot a short circuit . Fuse # 26 7.5 amp powers light switch & multifunction switch . Free wiring diagrams here http://www.bbbind.com/free-tsb enter vehicle info. year , make , model an engine size . Under system click on lighting ,then under subsystem click on headlamps . Click the search button them the blue link. Study the wiring diagram ,get a DMM - digital multi-meter an test the electrical circuits . Could be anyone of these switchs , wiring etc....

Alas, a problem for the shop. A bad wiring harness might be involved. But I would be overcome with the urge to check the fuses.

That sounds like the multifunction switch is the fault. The flasher on this vehicle is part of the hazzard switch. It recieves power for turn flashing from the turn signal switch. It is very common for the turnsignal (multifunction) switch to become worn and supply partial power to the flasher (hazzard switch) when not on which results in this fast clicking without any lights on. To be certian without taking out any tools whatsoever the next time the clicking happens jiggle the turn signal switch and see if it goes away or changes at all. If it does you need the turn signal switch. I'm going to include replacement instructions for that below because I am confident that is what you will need. Please ask if you have any further questions.



Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.
Disconnect the negative battery cable.
Disable the supplemental inflatable restraints (SIR).




Remove the tilt lever.
Remove the 3 Torx® head screws from the lower column shroud (3).
Remove the upper column shroud (1) tilting up and unsnapping from the lower column shroud hinges (3).
Remove the lower column shroud (3) from the steering column (2).
Remove the Torx® head screws (1) from the multifunction switch (2).

Hope helps.

SOUND LIKE WIRE PROBLEM.YOU NEED A WIRE DIAGRAM TO CHECK THE TURN SIGNAL SWITCH WIRING DONT PLUG A WIRE IF YOU DONT KNOW WHERE IT GOES COULD CAUSE ELECTRICAL BLOW OUT.TRY TO GO ON LINE LOOK FOR AUTODATA DIY COM LOOK FOR ELECTRICAL DIAGRAM.

From looking at a wiring diagram i would say the headlamp dimmer switch is bad . Testing the electrical circuit would be the way to tell for sure ! Not guessing an just replacing parts . Both hi an low beams receive B+ voltage from the same fuse's an HDLP relay . From there B+ voltage goes through the dimmer switch to ground . The daytime running lights are a separate system , different fuse an relay an lights . Do you know how read an use a wiring diagram for testing electrical circuits ?

The Trainer 32 How To Read An Automotive Block Wiring Diagram

Learning how to trouble shoot automotive electrical systems . This is how we fix automobiles

Code po551 is for the steering sensor. It senses steering pressure and bumps up the idle a little to compensate for lower pressure. The switch number is 5269625 and costs approx 35.00. It is threaded into the back of the steering rack and is accessible from underneath the car. Unplug the electrical connector from the switch, clean with electrical cleaner, remove and replace switch, plug in electrical connector. Disconnect the battery for a few minutes to reset the check engine light. Hope this helps.

im thinking it some how much be the head light switch shorted ????? Thinking doesn't fix electrical problems ! Learning how too does. Viewing electrical diagrams , testing the electrical circuit's with a DVOM - digital volt ohm meter , reading in a factory service repair manual how the affected circuit is suppose to work an using factory pin point testing procedures . That is what fixes electrical problems . Bet you replace the switch an it doesn't fix it . Without testing i could only guess as to what the problem could be . But an educated guess i would think a ground problem .I bet if you looked at a wiring diagram all these have same ground point near the back of the vehicle . Electrical voltage is back feeding through the circuit trying to find a good ground . But without out getting out the DVOM an testing this is just a guess. Looking at the wiring diagram all thing's your having problems with ground at the same place . G-400

>>>>FIRST disable the air bag system
You'll need to remove the upper and lower steering column covers.
Also all the trim under the drivers side, kneee bolster, etc...
The ignition switch has 2 screws holding it on.
Remove those screws and all related wiring harness.
Then the switch.
Here is the procedure from GM......

Place the multifunction lever in the center or the OFF position.
Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.

Disconnect the battery negative cable.
Disable the SIR system.
Remove the steering wheel inflator module.
Remove the horn plunger contact.
Remove the steering wheel.
Remove the tilt wheel lever.
Remove the ignition lock cylinder. Remove the upper steering column trim cover.
Couldnt find a diagram. Hope this helps.
