1970 Mark Headlight Door Questions

Hi Bill
I am restoring a 1970 Mark III. This is the first Mark III for me so I am learning a lot about the car. My question is about the headlight doors: while the car is running the doors are closed and they operate OK when the lights are turned on and off. Are they supposed to stay closed when the engine is off?
Hi Gregg –
Your question is a very common one and is a source of concern for many Lincoln owners including myself. The answer is YES they should stay closed for a period of time after the engine is turned off. As a matter of fact Ford has advised us in the past by special “Service Letters” that these doors or covers should stay shut on their own for a minimum of 24 hours.
Check the previous posts on our blog regarding this subject and I think that some of the answers there will help you to “tighten up” your system to prevent your headlamp doors from opening immediately after engine shutdown.
If you need more information or any manuals on this subject please do not hesitate to contact us.
