1966 Vacuum Concerns

Good morning Bill -

I have a couple of questions regarding the location of a couple of control valves on this vehicle.I am having an issue with the heater system as well as the door locks. I am looking for the location of the heater control box so I can verify lines and vacuum,and also the vacuum control valve assembly for the door lock system. I had the locks working due to open vacuum lines but now they stopped working again so I want to start from the beginning. Also, the selector valve, would that be the lock/unlock button on the door? Thanks. The service manual is not very helpful with locations of components.

Greetings Guy -

That control " Box " that you are looking for is used if your 66 is equipped with a Heater only, Heater and Manual A/C or the Automatic Climate Control. It should be located forward from the parking brake pedal, on the firewall above the headlight dimmer foot switch.

The vacuum door lock valve assembly should be located behind the left ( driver's side kick panel ) next to the parking brake pedal. The vacuum door lock control actuator is installed on each of the front doors in the center above the power window switches. Good luck with your repairs.

Sincerely,

Bill

Thank you Bill.

That must be that big square box that I saw under the dash. So the control actuator they are talking about is the switch as I thought. Thanks a lot. You guys are the best. I'm sure I will need some more things for this and when I do, I will be calling you.

Thanks for the nice reply and let me say that we certainly do appreciate your business.

1970 Lincoln Gas Tank Question

Good morning Mr. Bill!

I have a quick question; The gas tank on the 70 has a tiny leak under the strap. I want to replace the tank. I thought I read somewhere that the gas tank for a 70 is the same as the one used on all full sized Ford products for 1970, true or false?? Any direction you can give me will be appreciated. I have been looking everywhere for the data and not able to locate.

Tell the Mrs. hello for me and I hope to see you this winter.

All the best,

Carter

Hi Carter -

Hope that all is well with you. The old FoMoCo parts catalog shows that originally one of two fuel tanks were used on the these 1970 Lincolns. The first was p/n DOAZ-9002-A and was used on those with Evap Emissions. The second was p/n DOAZ-9002-B and was uses on those without Evap Emissions. These same part numbers were also used on other full sized Ford products 1969- 70 ( except stn. wagons). The difference in the part numbers was probably due to the emission venting provision at the tank. Will see you this winter.

Bill

Good morning Bill,

So ours (the dark blue 70) does NOT have emissions, correct?

Carter

Hi Carter -

I do NOT believe that your Lincoln has the evap. venting at the fuel tank as I have never seen, had to service, or look for any problems in that area on your car. It is possible that this particular vent set up was a California requirement only. Chris may be able to send you a photo from the 1970 volume two shop manual so that you can view the installation and then check yours out.

1964 Brake Light Issues

Bill -

I am in the process of finishing up my restoration myself and have found problems with previously done work (no surprise there!!)

I have been searching your blog and that of the Lincoln Owners club and can't get "relief" for my "problem". And I have been pouring over circuit diagrams in the Maintenance manual in an effort to find a solution.

So here's my "problem":

The brake lights didn't work so I replaced the brake light switch. Now when I press on the brake pedal the transmission selector dial light (on the steering column) turns on! But no brake lights. And at the same time, when I turn the headlights on, the transmission selector light does NOT turn on.

My research says that the power for the brake lights goes through the turn signal switch. Yet virtually everything else that connects to the turn signal switch works.

So I'm guessing wires are reversed in some way. But when I look at the circuit in the manual, page 15-6 FIG 1, I cannot determine where the transmission selector light wires could get "crossed" with the brake light wires. The black-blue wire that powers up the transmission selector light gets "lost" in the circuit diagram (up near the "CLOCK LIGHT" label) and of all the switches on that diagram, I don't see the headlight switch which should power that transmission light circuit when turning the headlights on.

Any thoughts you might have on this would be helpful. I am trying to avoid uncovering the turn signal relay switch since the circuit diagram does not indicate that the wires could get crossed up there.

Thanking you in advance for your help on this

Steve

Hello Steve -

Your issue as described is extremely rare as there is a multitude of wires that can be crossed or wrongly installed. You must have received this 1964 Lincoln in this condition. Your description and information on this problem is quite helpful.

There is a multi connector at the lower area of the steering column that directs the PRNDL bulb wire ( blue and black) and the Brake light wire (green) along with other wires up the column to the PRNDL bulb and the T.S. Switch. It is at this connector that these two wires could possibly have been interchanged inside of one side of the two sides of this connector. This is where I would begin to carefully examine the wiring. If all checks out ok at this connector, the feed from the B.L. switch and the PRNDL bulb can be tested with a test light at this location as well. At this time and because this exact problem is so rare, this is the best information that I can provide without further diagnosis information on your part. Good luck on a speedy repair and please keep us posted.
Sincerely
Bill

THANK YOU SO MUCH!!!!. I have been pouring over circuit diagrams and have been reluctant to just start tearing into "things". And this answer makes a lot of sense. And as a further check on this I turned the headlights on and virtually all the interior lights associated with "headlights on" came on EXCEPT the shift indicator light. And when I depressed the brake pedal that light also came on. But the stop lights never came on. And with head lights off, depressing the brake pedal again turned on the shift position light , but no other interior lights. So I feel pretty good about your suggestion.
A third party started restoration on this car several years ago and gave up because of the cost. I'm so close I can taste it J

Again thanks!

Steve

Bill,

You correctly assessed this problem. Everything works as it should.

Thanks so much!!!

Thanks for the update. Excellent to hear that you found the problem and in a short time also.

Bill
