Username Post: No left turn signals nor any brake lights        (Topic#351473)

On my 57 Belair,i recently had my brake light switch and my Ididit blinker assy literally melt.So I replaced the entire underdash harness,the ididit blinker switch,and the ididit conversion harness from the stock harness to the ididit column and the brake switch.Now most of the lights work;however I don't have no left blinkers front nor rear,and no brake lights.It blows the orange wire hot lead fuse everytime I apply the brakes.I figure that white wire from the brake switch must have a short.Because all the assys and courtesy lamps work fine until I apply the brake switch.All the parking lights and the right side blinkes work fine.Any ideas.Thanks

Make sure the harness coming out of the column is not pinched between the column and the dash, happened on my 51, with an Ididit column. Loosen the column, let it drop down a little, see what happens.

You have a short on the pink wire going to the left side brake light. Unplug the rear harness plug near the drivers kick panel and see if it still blows. If so the problem may be in the column wire as mentioned. If it doesn't blow when the rear harness connector is disconnected, it may be the pink wire under the sill, behind the rear seat or where the wires lay on the trunk floor.

NOTE: The pink wire changes color when it goes to the Ididit column.

The reason the left turn signal doesn't work is because the short opens the flasher so it won't blow a fuse, but keeps both front and rear signals from working.

Remove all the bulbs from the courtesy lights, and check to make sure that someone didn't put a single contact bulb in a place where there should be a double contact bulb, or vice versa. When I am looking for a short, I remove all bulbs or unplug the light from the circuit to determine if it is a wiring problem, or a bulb problem. I also use a plug in circuit breaker in place of the fuse, to save wasting a lot of fuses. I also have a bulb and socket with alligator clips at the ends of the wires, that I can use in place of the fuse, and the bulb will not blow out like a fuse. Go to www.youtube.com to learn how to diagnose electrical issues in your car. Youtube has lots of videos that can help you resolve a problem simply.

Junky and Don,
Thanks you both for all the help and advice. We are very lucky to have such wonderful and knowledgeable friend hereto help us.

While we are on the subject I have a problem with stop and tail lights. The schematic from the manual shows several wires coming to and from the stop light switch. My switch has only 2 wires?

Second observation is that my fuse panel has two fuses, one marked heater. My heater is not connected. The other one is connected to an Amp/Volt after market gauge that seems to work fine. There is no fuse in the brake position and no wire connected to it either. 1956 150 sedan delivery. Any better wire diagram out there than the manual?

The diagram only shows 2 wires on the stop switch. The 2 black wires plug into a plug that supplies 12 volts to the switch and also to the glove box light (red wire) and the plug also connects the green wires for the temp sender to gauge. The white wire in the plug connects to the steering column connector and goes to the turn signal switch.
There is no fuse for the brake lights on the fuse box. The fuse labled "brake" is for a emergency brake warning light option. The brake lights are protected by the circuit breaker in the light switch on the orange wire to the plug mentioned above.
P.S.: What is the problem with the brake lights and do the turn signals work OK? They use the same wires and bulbs.

no tail or brake lights, the blinkers do work. That's one of many things I don't understand. I am going out to do more checks right now. I will see if the stop switch works or has power. Thanks for anything else you can offer, you're a champ.

additional finding was the front blinkers, one was brighter than the other. found questionable connection on two spades. Replaced them and now one blinker seems to work correctly and the other one flashes both lamps at the same time?

That sounds like a poor ground on one of the front parking light assemblies.
Do the dash lights work? They are connected to the tail lights at the switch.

Does the dome light work? The tail, brake, dash, and dome lights ALL go through one of the circuit breakers on the light switch. May be a bad switch.

Dome has never worked either. I looked inside the steering column last weekend and need to repair the connection to the collar right now. as soon as I finish putting that back together i will be back to the rear light circuit.I will start where I should have started last week, with the switch. why would I do the easy stuff first? that makes too much sense! We both know how dumb I am. Thanks and will update as I go. I really appreciate the help.

Hey Don you were absolutely correct.I went through the entire pink circuit,and I ended up all the way at the rear of the car:at the licence plate.Two months ago I installed one of those billit third brake light frames,and tied it into the left side brake light assy.Apparently where the wire came out of frame,which is a tight fit,it had shorted out against the licence plate itself,and shorted everything on that circuit.After I removed the frame everything powered right up.Thanks again for your knowledge and help.Take care.Scott

Hey Junky,thanks for the response.I ended up shorting out the wire,when I recently installed a billit lighted licence plate frame.I tied the light wire into the left side light harness,and it shorted everything on that circuit.I appreciate your help.Thanks

AIRC, that 3rd lite should be run back to the brake switch

You must be a mind reader Don, I took your advice and yes that fuse is bad. The brake and tail lights worked since 2006 and none of the others ever did. The switch has been getting hard to pull out, so I am going to get another switch right now and hope that fixes some of my issues. Thanks for all the help and sticking with me, I appreciate it.

Got new switch yesterday and put it in today.
Now, tail lights work, reconnected license plate lights and they are back too.

Still no brake lights, and the front parking light passenger is on driver is off.

question, turn signal mechanism has some broken wires inside. I just disconnected the harness at the bottom of the column, could that affect the brake lights? Thanks for any help.

Yes, the white wire comes from the brake switch and goes up the column to the turn signal switch.
If the front bulb is good, check the plug on the inner fender for a bad connection. Link to plug.

follow up. Thanks for all the help Don, I appreciate it.

So far I have replaced the head light switch, and I think that fixed the brake/tail light issue. I replaced the turn signal actuator and harness and the bushing with the horn wire connection in the steering column. I think they were both ok, until I checked them. I replaced all the turn signal hardware, except the collar the turn handle attachs to. That will be next, because I think I tweeked it. It works , but is not as smooth as it was before I touched it. The front parking/blinkers are next on the list. Passenger side has parking light, driver side does not. Neither front blinker comes on. as I mentioned earlier, none of the dash back lights work, no dome either, but those light have not worked ever since I have had the car. Thanks again for the help and I will post more as I plod through this destroying as much as I fix. I am lucky Danchuk is just up the road!
