Light Problems like crazy

Make: Ford
Model: Mustang
Year: 1966

Symptoms: First and foremost, at times the left turn signal light within in the car wont come on and you will hear the flasher unit ticking. I checked outside of the car and the back left turn signal comes on, but the front left turn signal doesn't. At times, the turn signal flasher will not tick... when this occurs, the back left brake light doesn't come on.

Among other problems, When I pull the switch for my parking lights, I hear a crackling coming from the light switch and the front turn signals (parking lights) come on.. but then dim and flicker. When I pull the switch for the lights to come on, I still hear the persistent crackling eradicating from behind the dash (where the light switch is) The headlights flicker and cause all electrical items in the car to flicker as well (radio/radio light)... on top of that I dont have any tail lights or dash lights.

Somebody please post... I honestly need all of my lights to work especially tail and dash.... they are honestly becoming a great liability for me to take.

I have checked fuses... all good.

I took the car into a shop to get the dash lights fixed and much to my suprise all they did was replace a light switch and a fuse. A week or so afterwards the dash lights went out. Then all these electrical problems.

Someone please post... i'm itching to know whats wrong -- i'm gonna buy a new light switch pretty soon

thanks -- shawn 66 mustang enthusiast

I suppose so

I thought that was what the problem might be... just needed a second opinion.

Any other ideas would be greatly appreciated

also could 1 or 2 light bulbs that are blown throw the whole light system off??

such as a burned out license plate light??? and 1 dash light bulb being out?

Electrical gremlins can be a nightmare to most of us, but a fun puzzle to others. The noise you hear behind the das, near the light switch is most probably the built in circuit breatker that is cycling because of a circuit shorting. I would guess it to be between the switch and the front of the car and in the wire feeding the left running light or in the light socket since the left turn signal is not working (one element/wire) and the running light/headlights position cause the cycling circuit breaker. The first place I would look is where the two wires enter the light socket and then trace back from there to the switch if you did not find the problem.

The first thing to do is pull the battery cable off. Go and buy new bulbs if you don't know whether they are blown or not. Bulbs are cheap and probably could use new ones anyhow. CLEAN ALL of your sockets and make sure all of your grounds and contacts are good and clean. Go to someplace like Radio Shack and get some contact cleaner. Also use something like a small screwdriver and make sure the contacts are clean down in the sockets. Once this is done spray it down with contact cleaner again and replace the bulbs. Connect the battery and go from there. Also the clicking you hear from the small silver box is your turn signal relay or signal stat. If it is clicking it is working. A blown dash light will only show that something is not working whether it is working or not because the lamp will not light up to tell you otherwise. Replace your dash lamps if in doubt. Probably for less than $20 you can have all your lamps replaced except for the headlights. And if they look dim to you then replace them also.

Ponybuster,
Please see my reply to your other post as I had not read this one prior to replying to the other. I have experienced similar problems with my Galaxie.
Good luck, Skidmark
