1971 Mark III Questions

Hello Bill -

Sounds like you know your stuff - I've got one for you. My A/C is charged and ready to go, but will not blow out of upper vents. I took it to an A/C shop and they told me that I have a vacuum hose leak, is this true? How can I track this down?

Also wanted to change steering wheel out for grant wood grain steering wheel would this cause problems.

Complete loss of vacuum to the A/C controls will cause the system to default to full defrost and heat. Partial loss of vacuum will cause a drift towards defrost and heat when accelerating. You can track the problem down by reading the vacuum schematics for the A/C and performing the various tests as shown in the shop manual. You can start by looking for disconnected vacuum hoses under the hood and under the dash. In many cases this can be time consuming depending on your skills and if you have a shop manual.

Regarding your steering wheel question I have no knowledge what a grant wood steering wheel is. I would say that you should ask the steering wheel supplier that question.

Sincerely,

Bill

1965 Continental Sedan Window Issues

Hi Bill,

I'm pretty new at this so don't laugh if I ask stupid questions, ha ha. So I recently purchased a 65 Continental Sedan and even more recent, the windows stopped working. All of them. I've been reading the shop manual and it suggests a faulty 20amp circuit breaker. problem is, its not clear (at least to me) where its located. It says the located under the "cowl". whats a cowl??! haha. Either way, do you have any suggestions and or advice?? Anything would be greatly appreciated.

Congratulations on the Lincoln purchase. The cowl area where the circuit breakers are located on a 65 Lincoln should be behind the front passenger kick pad trim panel. The best way to approach this situation is with a correct wiring diagram and a 12 volt test light. The wiring diagram will show the breaker panel and wiring as well as the popular Power Window Safety Relay and how it is activated to supply power from the breaker to the power window switches. Section 17 in the factory Shop Manual also has a Power Window Diagnostic Guide that should be helpful to you. If you are performing your own repairs and have no experience in automotive electrical diagnosis you will be newly learning how to test these circuits in a logical sequence according to the wiring diagrams etc. Depending on your learning skills this will require patience and time. When you have done some of the diagnosing and have additional questions please contact us for further assistance if needed. If you do need the wiring diagram or any parts we should be able to supply your requirements.

Sincerely,

Bill

1978 Town Car Horn Issues

Hi Bill!

I'm having an issue with my 78 Continental Town Car. The horn won't work. It used to work just fine a couple weeks back, but then I took it in for an inspection (a safety for insurance) and it came out with no horn. Whenever I hop in and turn the key (to any position that activates the accessory power, including full ignition) there seems to be a slight hissing (maybe air?) from under the middle of the dash, which stops whenever I hit the horn button. But alas, no sound. I'm struggling to find where the hissing is coming from, but it seems constant. Any tips or help?

Also, just as a side note, would you happen to know anywhere where I can find replacement chrome bumpers? I've looked everywhere, but those things are hard to find for a beauty such as this!

Thanks in advance!
Tommy

Hello Tom -

You have stated that your horn became non operative after you visited a shop for a vehicle inspection. As the horn circuit can be disabled at many locations I cannot imagine what this other shop may or may not have done with your car from our location here in Florida. Therefore if the problem isn't obvious a technician in your area would need to diagnose the horn circuit beginning from square one with the use of the correct wiring diagram and a test light. It is a simple circuit but the correct wiring diagram and the ability to read it is an asset. The horn circuit is all electric and cannot cause any hissing that I can think of. To find out where the hissing sound is coming from someone with a trained ear near the source should easily be able to locate it for you. Your car has many vacuum operated accessories and many of these are located under the dash so of course I cannot pinpoint the source of the hiss with your description of " a slight hissing from under the middle of the dash". The only item that may activate and emit a hissing noise when you turn the key to acc. or "ignition" is the optional "Auto Lamp" feature if your Lincoln is so equipped. Have you considered this possibility?

George or Chris will advise you regarding the bumpers that you require.

Sincerely,

Bill

1979 Mark V Vibration

Dear Bill,

I have a 79 Mark V which I love, I am a loyal customer of Lincoln Land and I am planning a visit to sunny Clearwater at the end of this month and I can't wait to visit the showroom. My question is, when I accelerate I feel a vibration through the entire car, it gets worse at higher speeds and completely disappears when I release the accelerator pedal. There is also a "clunk" when putting the car into drive or reverse. I realize the clunk is a symptom of u-joints, can the u-joints also cause the vibration or should I be looking elsewhere?

Thanks for all your wise words over the years, Bill!


Kindly,

Sal

Greetings Sal -

We are glad that you are enjoying the blog. You are on the right track to consider "u-joints " as the cause of your vibration and clunk. A severe drive shaft out of balance and vibration issue can develop from worn u-joints. They should be carefully inspected with the car on a lift and replaced as necessary. Sometimes it is also necessary to re-balance the drive shaft. Another popular item to consider is the age and balance of the tires. Old tires can cause all sorts of vibrations. If your tires are aged, do not overlook the possibility that they may be contributing to some of the vibrations as well.

Sincerely,

Bill
