1969 Mark III Electrical Issues

Hi Bill,

I appreciate all you do to support Lincoln owners! I have a problem with my '69 Mark III. I purchased the car four years ago. A previous owner had disconnected the passenger side window motor from the original wiring and installed his own toggle switch and wiring. He installed it the dash ashtray where the lighter used to be. Pretty crazy but it worked!
I recently had a need to replace the front passenger side glass and decided to try to get the power window functioning with the original wiring and switches. I reconnected the motor to the original wiring. Not to surprising to see that the window would not operate with the door switches. I started pushing and pulling on various connectors. Low and behold, when I squeezed the window motor connector the motor worked using the door switches (driver and passenger switches). I unplugged the connected and adjusted the make and female connectors to improve the connection. Without squeezing the connector the window continued to function.

Once I had everything back together it no longer worked. I removed the metal trim from the door pad and wiggled the switch wires and the switch connector. Window was once again working!

Now I occasionally have a condition when it stops working. The drivers side window is also acting up but not as often. When I operate the power window switches (when the motors are not working) I do hear a click and I are the interior lights dim. I am wondering if this could all be related to a bad relay or a bad ground some where? When working, the motors raise and lower the windows quickly so they appear to be good.

Any ideas?

Thanks,

Brent

Hi Brent -

There are many things that can go wrong with power windows. You have already identified one of them. Why not repair all of those bad connections first instead of wiggling wires and hoping.

We have the wiring diagram available to you at no charge. Sign in as a 1969 Mark III once you're on our Website, go to the REFERENCE - TECH INFORMATION & PARTS DIAGRAMS section and Click on the Wiring Diagram.

Then you can move on to the switches and the other problems one at a time. It does seem from your description of the previous work that you will find much more to discover and repair.

Sincerely,

Bill

1979 Mark V Free Play In Steering

Hi Bill,

I bought a 1979 Mark V December 2016.It has an excessive amount steering wheel free play. After I bought new tiers I had the front end aligned. The only worn part was the left tie rod end, and they replaced both sides. Is there a steering box adjustment to adjust the free play? Driving down a straight road is not good because of the free play. I also have a 1957 Ford Sunliner that has an adjustment screw on top of steering box to adjust the free play. Dose my Lincoln have an an adjustment like that? I haven't been able to find one.You have a great web site.

Thanks for any help,

Lyle

Greetings Lyle,

You post that the only worn part was a tie rod end and then you state that there is free play in the steering box. Free play in the box can also be caused by worn internal parts. The adjustment on the box will not remove play that is caused by worn bushings etc. within the steering box. In my opinion you will need to visit another front end shop and explain the situation to them. The technician will then inspect your steering box very carefully after a road test and advise you. If you were at our shop at Lincoln Land we would lift your Mark and examine your steering system after road testing. The poor steering is usually caused by the sum of all of the worn parts and looseness. The initial road test by the technician is very important in order to perform correct and complete diagnosis.

Sincerely,

Bill

1959 Will Not Restart When Hot - New Engine Rebuild

Bill,

Restoring a 59 Mark IV. Had the engine professionally rebuilt, preformed break in on motor, but as the car gets warmed up, when I turn the car off - it will not crank back up until the car cools down for 15 minutes. We have replaced coil, points, condensor, temp sending switch was also replace at rebuild.

Signed,

Orlando,

When this happens ALL of the general tune up items need to be verified. As well as the items that you have already tested, checked or replaced this will include battery and all starter and ground cables, starter, spark plugs, carburetor and choke etc. Other possibilities are engine severely overheating or the crankshaft vibration damper slipping and subsequently causing you an incorrect timing reading. If all of the above is in good order it may be time to contact your rebuilder. Good rebuilders will immediately become involved in these situations.

Sincerely,

Bill

1978 Mark V High Beam Question

Hi Bill -

Is there a way to manually control the high beams with the switch on the floor in a 1978 Lincoln Mark V? I turn the auto dimmer to off and press the dip switch with my foot and nothing seems to happen. At other times all 4 head lights light up. I do not seem to be able to consistently control them. Alternatively, is there a simple way/fix way to keep them on all the time? I have to drive through some dark streets to get home and do not want to hit a deer.

Thanks in advance,

Dean

Hello Dean -

You are correct. If you rotate the H/L dimmer rheostat to the extreme position into the auto dim "off " detent position, the system should then be in the manual mode. This will be shown in the owners manual as well as the maintenance manual. There is also a 4 amp in line fuse under the dash that can be pulled as an additional test. If this does not work, the system will need to be diagnosed as per the maintenance manual. I would probably start the testing at the foot switch. We do have owners manuals and shop manuals available for shipping.

Sincerely,

Bill
