1979 Sedan New Owner Turn Signal Issues

Hi there Bill,

So I recently bought myself a 1979 Lincoln Town Car in blue. Shes got some issues that we knew about purchasing the car such as the exhaust system and brakes. After getting the car delivered we ran her and gave her a look over of the lights, all the lights work, reverse, break, tail, head, and high beams, and also the hazards. But once we move the signal arm nothing. No response from the dashboard or the lights on the outside of the car. I have a guy loves working on 70' New Yorkers. I'm not sure if the inside of the steering columns is similar in those cars as it is the Lincolns. The arm does hold its position when it is up or down. Also another quick question to go along with the signals, when the hazards are on our left turn arrow on the dashboard also doesn't light up. What could that issue be?

Sincerely,

Jon

Hi Jon -

Congratulations on your recent Lincoln purchase. The fact that you seemingly have no knowledge of any previous repairs or testing of the turn signal circuit and have evidently not had any diagnosis performed at all by any one so far does not help me at all to pinpoint what has failed. Some common fail items though for this issue that we often see are:
Faulty T/S switch
Blown fuse
Faulty or missing T/S flasher
Disconnected wiring or damaged wiring circuit somewhere
The wiring could have been tampered with by some previous owner

If you are able to speak to the previous owner about this problem, you should ask him or her what they know about this issue. This would be a good place to begin. It is handy to have a friend that loves to work on 70 New Yorkers. New Yorkers have similar wiring circuits as Lincoln however they are probably different enough that the Factory Service Manuals and Wiring diagrams are necessary to properly diagnose and locate many electrical problems. Your New Yorker friend may even be persuaded to love working on 79 Lincoln Town Cars.

We have these manuals and wiring diagrams available when you are ready and we look forward to supplying you with any parts that you require now and in the future. We wish you good luck on an easy diagnosis and repair.

Sincerely,

Bill

1973 Headlight Warning Buzzer

Hello Bill,

My question is where can I find the headlight warning relay/buzzer for the warning system? I have the factory service books and cannot find this information in the Electrical #3 book. The bulb and the door switch checks out ok. Thank-You! Your help is appreciated!

Hi John -

It is good to hear from you as it has been quite a while. It appears from the master wiring diagram that the H/L On warning system shares the relay and buzzer with the Key Reminder system. Both the buzzer and the relay are located behind the instrument panel above the glove box. Remove the glove box assy. and look for them above and behind the the instrument panel. It looks like a complicated wiring set up so you may need a copy of this wiring diagram. Let us know if we can help you further. We should have these two parts in stock should you need them.

Sincerely,

Bill
