Username Post: tail lights won't turn off        (Topic#343233)

My tail lights won't turn off unless I disconnect the battery. When I pull the wire going from the light switch to the rear lights they shut off. When I connect the wire to the terminal on the light switch the tail lights turn on. Brake lights work fine. Headlights function as normal.


Is it a bad switch not turning off my lights? Is there some other wiring from another source I should check?

Is the black wire on the correct terminal? Do the front park lights work normally? Do you have 4 way flashers? Is the 4 way switch activated?

Please take a look at the picture of my wiring on my switch on the tinyurl in my signature. That might address your questions about the existing wiring.

The front park lights have never worked. 4 way flashers have never worked. Blinkers used to work, they don't now. What is or where is a 4 way switch?

It looks like you have the gray dash light wire next to the tail light wire, instead of on the dimmer post. Try taking the gray wire off the switch and see if they go out. You may have the dash lights wired wrong.
Aftermarket tilt columns have 4 way flasher switches.

I'll try taking the gray wire off the post.

The gray wire goes on one of the the three terminal posts next to your thumb in your photo.

Taking the gray wire off didn't make the tail lights turn off

The gray wire isn't the issue. The issue is that the black wire is connected to the wrong terminal on the switch. Before you do anything else, look at the drawing posted by acardon. Then remove the black wire from the terminal it is connected to now and re-connect it to the correct terminal as shown on the drawing.

Ray,

The parking lights turn on when I pull the switch one notch. The headlights turn on and the parking lights turn off when I pull the switch again.

The black wire looks to be in the same exact spot as the drawing. Keep in mind the drawing referenced shows the switch from the bottom and my pictures it from the top.

When I disconnect the black wire, the tail lights go off. I'm suspecting the switch isn't turning the rear tail lights off.

Thoughs?

Hi Paul, unless there was another change made to the circuit prior to the lights staying on I'd say you have a bad switch. Replacing it may also cure your lack of front parking lights also.

It's designed for the front parking lights to go out when the headlights are on. The headlights and parking lights use the same circuit breaker in the switch. If both were on, it would cause a overload.

Parking lights do work. I mis-spoke early in the tread. Before I attempt getting a new switch, is there any other wiring I can check? Does the black wire from the light switch go ANYWHERE under the dash before it goes to the tail lights?

Could there be a loop somewhere? I'm pretty good with electronics, and I deduce the switch is bad...but...I'm not ready to buy into a bad switch.

Actually, I should, I've replaced that switch about 4 times in the last 12 years.

Last thoughts?

If taking the wire off the switch kills the tail lights, the wire isn't picking up voltage from anyplace else. You could take the wire off the switch and measure the tail light terminal for voltage with the switch off. You could also temporiarly put the black wire on the front parking light teminal or the headlight terminal and see if they come on and off with the switch.

Paul, looks like your narrowed down. Curious, what is the gauge by your left knee & it looks like a button switch maybe above it next to the column?

My last thought would be DON'T buy a repro switch. They aren't very well made.
See if you can find an original on eBay or from someone on this site.

Where your knee would be.

Can't figure how to attach picture. It's in your picture post, a shot under the dash.

I took the headlight feed off the switch, I put the rear tail light on the lead on the terminal of the front lights. the problem is the switch. I can control the tail lights with the switch while they are connected to the headlight terminal.

I bought a replacement stock switch, it's an original unit, not a reproduction. I can't seem to pull the arm out to turn on the lights. It's jammed in there. If I try to depress the spring to pull out the rod, no luck either. Can I disassemble it?

You can take them apart.

As I remember there are little steel balls under spring tension that fly out in all directions if you are not careful. These are what make the switch click and hold when moved to the different positions.

I think what may have happened to your switch is that you are supposed to pull the headlight switch to the full on position before pressing the button to remove the knob and shaft.

If that wasn't done before and removal was forced then when the knob was put back in it became jammed when forced back in.

Take apart that POS reproduction first for practice maybe.

Good luck.
