1979 Mark Headlight Switch Questions

Hi Bill....

My 79 Mark V has the autolamp system which allows for auto dimming of the headlights from high to low beam and has the delay feature for the lights to stay on after the car has been shut off. My question is do you set the flag dial to the right and left of the headlight switch with the headlights off on the car?? The reason why I ask is when I turned the lights on the other day and tried to move the flag dials they were both real loose..I am not sure if it is broken and I need to replace the whole switch..If I need to replace he switch do you have a replacement and how much are they??




Hi Bill -

Both of those AUTOLAMP adjustment tabs on the headlamp switch can be moved to a new setting at any time with no problems. This operation will be explained in the owners manual as well. You should inspect the switch to find out why these tabs are loose before purchasing a new switch. The fix could possibly be simple and easy to see and repair by yourself. If not we can repair most switch problems for you with the spare parts that we have available or we can special order a new switch if necessary.

Repairing and testing your switch would cost $125.00, and a NEW one (if needed) would be $275.00. After you or your mechanic have checked your switch for a simple fix and find that you need to have it serviced here or a new complete switch ordered please give George a call at our office. In any case, please let us know what you find and good luck with an easy repair.

Worthwhile Tip for collectible Lincoln owners...

Greetings fellow Lincoln owners -

Whether or not you are planning on doing your own maintenance and repairs, the correct FoMoCo Shop Manual and Wiring Diagram set is a must for you to have at your side. The pluses for having this information on hand cannot be over emphasized. They can save you many hours of confusion, along with saving you from replacing parts that are not faulty, etc. However if you are having a local favorite technician diagnose and repair your Lincoln, he or she will be delighted to have these manuals available as a reference as they could speed up the procedures and even save you many dollars and time wasted. Used correctly they can be the most valuable tools in your tool box.

The factory manuals have changed over the years and after approximately 1967 the detailed wiring diagrams were a separate publication and therefore needed to be obtained as a separate item by the Dealers from FoMoCo. In some years, there are even separate vacuum diagrams to aid in your repair.

If you would like more information on these manuals please contact George at our Lincoln Land office at any time...727 446 2193...
