    its not hookd to a cont power source. It just shorted out somewhere and I cant seem to figure it out. Theres either a relay melted somewhere or something. Maby even part of a fuse pannel is melted. I dnt thnk it would be melted though as I noticed right away when the short happend. Seems like it should just be as simple as replacing something somewhere but I dont k.ow what

Check your fuses, shorts blow them.

Testimonial: "yeah i did that, i also replaced the sentinel a while ago and it didnt seem to solve anything. i unhook the radio and change the fuse and everything seems to work, but everything stays on after i shut the car off. where could this problem possibly be?"

    Sounds like you have the unit hooked up to a continuious power source. Find an ignition controled power source. original sterio power, cigerete lighter, anything on your ignition accessory power circute.

    It is not a good idea to have your radio hooked up to a continuious power circuit.

    Check your wiring on the radio, only way I can see that it would stay on all the time is if you mixed up the Orange (hot at all times) and the Yellow(Hot on Acc or run) wires.

There is a body control module that may cause this issue, it has the ability to be tested, have that done first.

check for any circuit brakers near the fuse box, if theres any of them reset them by introducing a paperclip in the small hole and press, you will hear a click.

SOURCE: '91 Subaru: dash & running lights won't turn on with headlights

This is a problewm I have been researching. On the 91 Loyale there are two headlight relays. The relay for the left headlight also controls the instrument lights and the running lights. If the right relay is working and the left is not, the left headlight will be dim because of a back electrical path through the high beam indicator light on the dash, but the instrument and running lights will be out. I have been trying to find out where Subaru put these relays, but three Subaru service departments have been no help. One dealer's service department told me to remove the large bezel around the instrument panel. I did and the relays weren't there. Lots of luck.

After haveing a aftermarket radio installed, the low beam headlights and the brake lights dont work. The high beam lights will work if the high beam switch lever is held on.


Could be a wire behind the radio. I had a Camaro that had no dash lights after an aftermarket radio was installed. Almost never found the problem. And the company that installed the radio would not admit to causing the problem....even though I had a detailed description of the problem from the tech that fixed it. Wish I had better news for you.

I was installing an after market Pioneer CD Player into a 1993 Suzuki Swift. I installed it with all the right wiring and everything was working fine with the stereo. Once I turned the headlights on, that...


The adapter harness for the radio is probably not wired correctly. I'll bet you also have no tail lights. You probably wired the harness so that the illumination circuit for the factory radio is wired to the wrong terminal of the new radio, thus the problem occuring when you turned on the headlamp switch. I have seen this many times when someone is trying to wire a radio adapter harness without having access to the factory wiring harness diagrams for the vehicle...the wire colors on the adapter harnesses don't allways match the wire colors of the factory harnesses. You need to know which wire is which and wire the correct wires together regardless of what color they may be. If you wired it simply by the wire colors, it most likely is not correct.
If you are lucky, it only blew the fuse for the tail/dash lamps. It is possible that you now have some serious vehicle wiring harness damage caused by the short circuit that was created.
I would disconnect the new radio and get the car fixed first. Then you need to find out which of the wires in the factory harness is for the illumination circuit and make sure that nothing is connected to it on the adapter harness. Most aftermarket radio/stereo systems do not use this circuit at all.

The clock, speedometer, gas gauge, etc.. won't work.


No need to say you obviously created a short circuit when you installed the radio and something got fried.
Could be the dimmer, you could try to bypass that but in all honestly I think it is best left up to a pro.

Tail lights out as well as dash lights. 1995 pontiac bonneville


you need a head light switch. buy from carquest (significantly less expensive then dealership).
remove knobs (small insert on pull knob press in with a small flathead while pulling towards you, twilight knob pops right off)

take off the cover plate over steering wheel (pop out with flat head screwdriver)

then cover over instruments (small torx bit 5 screws, 2 hidden by previously removed cover).

three small bolts hold in light switch.

No dash lights or dimmer control after installing a stereo system


Check out the Dimmer Switch Assembly - it may be faulty or there may be a short. I had a simular problem - resolved by replacing.

Tail light fuse keeps blowing


Terry: It's obvious I'm not dealing with a USA spec car, however, I had lived in the U.S. Virgin Islands and am quite familiar with the Bluebirds of the past. Nissan still uses the same basic circuitry designs as far as what circuits serve what. Here are the circuits to look at.
All lights which are switched on by the headlight switch. This includes the Cigarette lighter back light, radio light power supply, automatics have shifter back lighting as well as your climate controls and all dash lights. Your side marker lights are also served by this circuit. The dash lights go through a type of dimmer switch which essentially creates resistance, thus dimming the lights. Sometimes the clocks are tied into the circuits. Start with the simple things first and work your way in. There is a type of fuse called a circuit breaker which will plug into the fuse block in place of the fuse.
Get the same rating as the one you pulled out. DO NOT USE A JUMPER WIRE AND LET THE SMOKE OUT OF THE WIRES!
If the circuit breaker blows immediately, you have a serious short!
With the circuit breaker, if the short is not real bad, the lights will burn for a little bit before the breaker blows. Once it cools, it will close and the circuit will operate again. While it is in operation, you look for the lights that operate and the ones that don't. Check the ones that don't. Although it's rare for a bulb to cause a fuse to blow, it does happen.
I often find problems are due to radio installations or other types of installations. So if you don't have a factory radio or if you have some type of accessory which has been installed in the console or dash, this would be a prime suspect. Nissan's are not really known for electrical problems unless they have been in collisions. If your car has been in a collision, look in the area where it was hit. You may find a pinched wire or damaged insulation. I am not quite sure what model your car would compare to in reference to a US car.
The Bluebird's were 510's. Are the Maxima's now? What ever model it is, unless it has no sister model imported to the
USA, the odds are that the circuits are going to be real close if not identical! I hope I have been of some assistance. Let me know.

My dash and radio lights go out when I turn on my headlights.


hi mate i owned a caprice classic on a 98 renown for electrical problems because there is so much electrical equipment on them try disconnecting the radio first and see what happens and try disconnecting the dash and see what happens failing that it could be any bulb in the car causing a short as the lioghting circuit is linked into the radio good luck

It certainly sounds like its a short in the switch or a problem in the loom that is shorting out the dash and radio ancillarys circuit.

Its not good news but for sure the right place to start is the switch I am affriad. could you get a separate switch unit to swap out and test ?
