1964 New Owner HVAC Issue

Hi Bill.

I have a problem with my HVAC control switch. It shorts when I adjust it, the fuse doesn't blow either which is a worry... I haven't investigated it yet as my car has only recently arrived in the UK. I only seems to have one speed and it only blows cold. Should I just look into replacing the unit or is there other things to investigate first.

Thanks.

Martin

Greetings Martin -

Congratulations on your recent 64 sedan purchase.

Why do you think you have a shorted circuit? What are the symptoms of a shorted circuit that you are seeing? Having only one speed on the blower indicates a problem but does not indicate a short. To answer your question, yes, there are other things to investigate before replacing all of the parts. Diagnosis is necessary before replacing any part in order to avoid replacing expensive parts that are already in good working order. Diagnosis should be performed with the use of the proper shop manual and wiring diagram. Have you spoken to the previous owner yet to find out what he or she knows regarding this issue?

Your symptom of " seems to have only one blower speed " indicates a possible faulty blower switch or blower resistor. I would check the blower controls and wiring etc. first. Look to see also if any one has bypassed a fuse or breaker or messed at all with the original factory installation . Good luck on an easy diagnosis and repair.

Sincerely,

Bill

1968 Automatic Temp Control Question

Bill -

On a 68 with a 460, and automatic climate control should the heater fan blow before the engine warms up and the temperature is warm? My fan runs on high when it's cold. 2nd question is related, does the temperature switch do both the idiot light and the climate control or are there two sending units?

Hello Jason,

The ATC on your 68 Continental was quite a sophisticated system and operates very nicely if all is in good order. The blower motor operation will be delayed anytime that the dash control lever is in the High or Low position and the engine is cold in any weather and the system is in the automatic HEAT mode. If and when the system drives over towards the COOLING section with a cold engine the blower operation will be immediate. The blower fan motor will NOT be delayed if the mode lever is in the "defog" or "deice" position at any time. The reason for the blower delay is so that the occupants in the car will not endure a cold blast of air when heat is needed.

The atc system does not operate, control or effect the high temperature warning light and this light sensor does not operate or control the atc. There are two separate sending units that are side by side in the same switch assembly.

At the present time we at Lincoln Land do not have a right hand mirror for your 68 Continental. I notice that they have become very popular. These types of parts do show up however from time to time. Finding accessories such as these mirrors makes the car hobby even more enjoyable.

Sincerely,

Bill

1961 Continental Convertible Noise When Turning

Bill -

I am having problems with my power steering on my '61 convertible w/ ac. It was making a whining noise when turning. Thinking it was air in the fluid I have tried bleeding the system with the wipers on. I tried using a vacuum on the filler tube but could not get vacuum to pull. The whining has somewhat decreased with the method of turning the wheels 10 times and letting it bleed out air. As the wheels approach the stops the noise gets very loud. Is there something that makes the noise at the stops that might be fixed?

The power steering and wipers are working fine and I really don't want to pull and replace the pump if not needed.

Thanks,

Phil

Hi Phil -

Those p/s whining noises sure can be annoying as well as an indication of a problem. Has any work at all been done in the last while to the p /s or the hydraulic wiper system? Was the pump or other hydraulic part removed recently for some other procedure? Why did you think that there was air in the hydraulics? Did you see foam in the reservoir or? How did you learn to vacuum out the system as you describe? Sorry for all of the questions, but a good working undisturbed system does not suddenly ingest air. I will await your answers.

Sincerely,

Bill

I hadn't driven the car for a few months and when I moved it to drive I noticed more whining noise .

I read on a website that hooking a vacuum to reservoir would help draw air from system. As I said I could not create any vacuum. I did not do any work on wipers or ps. I just took it for a test drive and steering and wipers worked fine with an occasional resistance in steering . But fairly loud whining noise.

Would pump go bad from just sitting? I do notice some bubbling on the ps dipstick.

Hi Phil -

In that case there are three possible things that you can check before condemning the pump. The pump pressure can be tested at operating pressure by a knowledgeable shop as per the shop manual and compared with the specs in the manual. The p/s fluid filter can be checked for plugging or an incorrect filter that is restricting the fluid that returns to the pump. Lastly the pitman arm can be disconnected at the linkage so that the complete steering linkage and the steering shaft with the box can be checked " separately " for any binding. You may want to discuss this further with your mechanic first to see if he agrees. Keep us posted.

Sincerely,

Bill

I'm not sure on the location of the ps filter. Like to look at that first.

Thanks,

Phil

Hi Phil -

The p/s filter should be located inside the p/s reservoir under the top cover. Be very careful to observe how the filter is installed ( if there is one still installed ). If you do not have the proper shop manual for your Lincoln you will find that this problem and future problems will become more difficult. The FoMoCo manuals that we recommend and sell can also help your mechanic if you yourself are not performing some of the diagnosing and repair procedures. Good luck with a quick diagnosis.

Sincerely,

Bill

Thanks/ I have a shop manual and I'll work on this tomorrow.
