Tail/Parking/Dash light issue
First of all I just wanna say this website is awesome, I have fixed quite a few issues on my own with all the awesome advise there is on here.

However, I have run into a issue that I cant find a answer too on here.

About 3 weeks ago my dash lights started flickering on a off, if I would tap on the headlight switch they would come back on. Well on my way home I got pulled over for not having my tail lights on. When the officer walked up I tapped on my headlight switch and they came back on. Well that has stopped working for me and now they don't come on at all.

Here is what I have replaced and done to find issue
-Changed all the bulbs
-Replaced the headlight switch
-tested the wires on the switch and found that red/blue wire is dead & the brown/white wire(bottom wire on the switch)

I have searched and searched for grounds but they are almost now where to be found. IF it is a ground issue where should I start looking, I pulled up the wireing diagram and it looks like japanesse.
My jeep also has a after market trailer light adapter on it and when I unplugged it I noticed that the hazards and blinkers didn't work until I plugged it back.

Any help would be awesome, Im driving my freaking Honda right now at night during the best time of the year cause I cant figure this out.

Thanks :confused:

disconnect the switch and use a multimeter to confirm you didn't get a bad switch.
as for grounds, I believe all (or most) of the dash stuff is grounded to a bracket by the e-brake pedal

Good luck

Did that and the wires that arent getting power are the red/white and the blue/red

I have looked all around the parking brake for the ground, all the black wires run throughout my dash. Is there a second place to look?

deffictive new headlight switch

It's your dimmer switch for the interior lights but i am not sure how it relates to the tail lamps. If it is a ground you should see power at the tail lamps with the meter/test light by checking it to a good chasis ground point. Post back what you see.

I will check those this afternoon, my dimmer switch is still able to turn my cab lights on when i roll it all the way up. This might be a dumb question but where should I check with my meter at the tail lamps exaclty, the wires? or the bulb housing?

Que89YJ 10-15-2013 11:52 AM

Check the bulb socket.
Also when the tail lights do not work, do the brake and turn signals also not work?
Does tapping on the light switch like you mentioned before still cuase them to flicker?
Do the guage lights always flicker with the tail lamps?

brake lights and turn signals work. taping on the switch does nothing anymore. that worked like 2 times.

Que89YJ 10-15-2013 12:56 PM

The tail lamp grounds are good then. It has to be a power issue. What about the dash lights?

bdub2 10-15-2013 01:06 PM

dash lights do not work along with the parking lights, but my turn signals up front work too

I dont have the wiring diagram for a 92 handy but the switch wiring is pretty standard. Power is fed through Fuse #8(20 amp) in the fuse panel at the drivers feet (Pink/Red wire ?) E on the Headlamp switch connector, The power feeds through the switch to power the output for the tail lamps and panel lamps on (Black/Yellow ?) A on the connector. Check power to the fuse then at the connector pin E.

the 4 wires I have that come off of the switch are, red/blue, red, red/white, tan/black, brown/white, and larger wirer that is red/orange. all of my fuses have power showing, Im not sure what connector pin e is?

Que89YJ 10-16-2013 11:15 AM

Check power on red/white. It is fed by fuse 8 and should be hot all the time. You said you only had power on one wire and that was the red orange. You said you checked all the fuses but you need to specifically check for power on both sides of fuse 8 if the red/white doesnt have power. If you do have power to the red/white then check the output on red/blue (My wiring says blue/red) with the lights on. That is the common output to both. Here is a link to a basic wiring diagram:

bdub2 10-17-2013 03:42 PM

I have no power to the red/white or the blue/red. I have power to all the other wires

bdub2 10-17-2013 04:03 PM

ok, so fuse 8 blew. I replaced it and now im good. Not sure why it blew because I checked that fuse when all this started and it was fine. But im in good working order now. Thanks QUE89JY
