Welcome to Mustangsandmore.com. 
I would start by checking and/or replacing the turn signal switch. You may also have a loose connection or ground in the turn signal switch. Start with the point at which the problem occured and work your way back until the problem is fixed.
Again welcome to the M&M extended family.  Dave & Terri

Thanks Dave and Terry for the quick response...The switch assembly was new "ford" two years ago....could you explain how this would cause the headlights to not light at all?...I understand how this could possibly cause the the signals to be related....

Ogor, Welcome
I agree with Dave on the turnsignal switch, but also look at your light switch. Since the turnsignal switch is fed from the light switch, I also sounds like something might have broke inside the light switch which is causing everything to flash. One of the contact could be shorting out others. What year is the car and how old is the light switch?Mike

Thanks again for all the help...and quick to...the headlight switch is most likely the original...or an older replacement as I have had the car for 4 years and it's one of the things I never replaced....Headlights...New Halogen 10 days after the car was bought..turn signal and harness assembly...2 years ago...from Ford...Dimmer switch..last spring/summer...Until today...all systems work fine...yup..until today..coming home in the dark from a show...that stank! Hey to all helping...check out my car at mustangs68.com under specials...it's 1 of 481 lost cars..the Gold Nugget Special...great photos of a rust/bondo free car...truly a unique ride!

Are the lights is the dash bright when they flash?I would check your grounds, suspecting backfeeding. ------------------

Steve, yes, the left, right and highbeam indicators all "brighten" when I activate any turn signal. As I noted earlier, they all come on together when I pull the headlighs on...but no headlights!What grounds (and where) should be checked...wiring is not my area...but I'll learn... I have ordered a New headligh Switch as a place to start....any other suggestions is appreciated...from anyone!!

As this posting...the lighting problem is not fixed....solution (based on help) is 1. Faulty Light switch 2. Bad wire or short in column harness assembly 3. Ground short somewhere.I have a new headlight switch coming...and plan on pulling the steering wheel and checking the connection under the dash...but if i'm looking for a short or loose ground somewhere...I don't know where to look or check... How does the headlight switch short out and affect the stuff in the steering column? Help in the answer would be great!!!!
Thanks everyone...this forum seems to work!!!

My money would be on a bad headlight switch. You stated that you have Halogen lights, they pull a lot more current than standard lights and are very hard on the circuit breaker built in the headlight switch. I would change the headlight switch first, before tearing into the turnsignal switch, and see if it cures the problem.------------------

Damn! Tonight we changed out the headlight switch....it did not do the job...pulled the steering wheel...for a split second the headlights worked then went out...It really torques me because I put in a new turn signal assembly and harness not that long ago....at least not so long as to remember attaching and re-using all the wires...but it appears that this "genuine ford part" could not last 30 years! I'll spend more....buy more and install more.... Hopefully this cures the darkness... Check out my car....go to my profile and see the "survivor" one of 481 lost cars! The Gold Nugget Special....

I had something wierd going on with my wiring awhile back, similar story. Turns out I had some heavy boxes in the trunk and they mashed up against the wiring to the rear light buckets, basically rubbed a hole in the wiring insulation, and shorted out the wiring. As for finding a short, you are looking for exposed wires, broken/cut insulation, a loose connection or screw (ground). Although everything may have been fine yesterday, the last ride you took may have had enough vibration to rub something the wrong way.

Hot Damn...kinda! Today I woke up early...and started on the replacement of the turn signal assembly....It seems that the last time I put the column together ""I"" forgot the grease on the horn contact...so I cannot blame ford parts!...I did completely redo this assembly with "new" parts and greased it.....horn works!Hooked all together...and .....NO LIGHTS!!!!! In frustration...leaning over to once again disconnect the negative battery terminal...I see....frayed wire from alt....going to loose bolt on bracket to block...move wire...lights... As you can tell I know I was lucky! Yup...loose ground as advised earlier... Start with easy...and inexpensive...ideas and then work hard....to all others...this forum was great... Thanks to all who offered advise and help...keep up the good work! Bill

after you check the grounds, check the circuit breaker it may have been fried. if so then after you replace the circuit breaker, you might consider using relays to switch your lights on so as not to burn up the 30+ year old hardware that was not designed to carry the current that is demanded by the halogen headlamps.

Too cool. Funny how electrical gremlins can bite you where you least expect it.
