A/C without Climate Control??

[Michael Vogler]

I spotted this deVille online with A/C with a direct On/Off lever, rather than with Climate Control.  I have never seen this.  Was this an option from the Climate Control?

[Kurt]

No. As far as I know "Comfort Control" was the only option for A/C in 64. It may have been retrofitted. Comfort Control is complicated and parts are scarce.

[Michael Vogler]

That’s what I believed to be the case

75 Series (Limos) and Commercial Chassis 1964 body styles had the simpler AC/Heat System like found in the 1963 and prior with the slide control. If this is a 64 deVille it could have been changed out at some point with the 1963 and earlier style or 1964 75 series style.  Perhaps there were issues with the comfort control and converted to the simply non Comfort Control type unit?

You can of course convert a Non-AC car to factory AC but it is a huge effort which is covered in some detail on this Help Page article:  - Air Conditioning: Converting to Original A/C from a Non A/C Car

Just to note the Dash pad at the far left the way it has the squared and notched cut looks sort of like a 63. The 64 dash pad end was more smooth without the deep notch.  The door pull handle definitely looks like a 64 deVille style vinyl door closure pull handle.
Interesting picture... at least what you can see.

Thanks Jason.

While AC would be nice to have, because of all the extra chrome on the dash your get with the vents, I don’t need it here in Huntington Beach.  And honestly, I really like NOT having to maintain the Comfort Control.  Depending on the weather out here, it’s either heater on or top down.  Frequently, it’s even the heater on AND the top down!!

Attached is a wider pic of the dash of the car in the previous pic.

dash pad is definately 63. no cut out for the a/c sensor grill and the guidematic sensor on the top. the 64 has the ac sensor grill just above the center of the steering wheel and the guidematic sensor is in the lf fender. looks like a mis match of 2 cars

... and look at how the jagged dash left end does not butt up well to the 1964 door dash extension.  Not a good fit. And now with the wider view and as Maurice pointed out you have no dash sensor grill, and the Guidematic Photo Tube on the dash.  The dash Photo Tube and no AC Grill would have been found on a 1964 Series 75 (for a 75 equipped with auto dimming), but the left side of that dash pretty much confirms it is a 1963 dash pad.  And not to mention the 75 series/CC dash pad is also different from the other body styles.

Here are the tells I see:

[Jason Edge]

Kurt, it is hard to say how this was all put together. The elongated grooved levers were used on the 1964 Serie 62, CC and 75, they are not specific to 63. That looks like the placement for the Twilight Sentinel just below and to the left of the wiper switch. This was a new for 64 option. The defogger had the squarish control box also but was usually located more to the left where the smaller convertible or partition window switch would have been. I did not click the picture to see the 63 glove box script and now see it. Most things here like the levers would have been correct for either year depending on body style, etc. or switched, so just hard to say how the 63 & 64 stuff was put together.  The 1st thing that jumped out at me was the dash to dash extension fitment as this is the main physical difference between the dash pads if you have no "optioned" items otherwise.

[Kurt]

Not all 64 levers had color plastic caps? It looks like the turn signal lever does but the tilt lever doesn't . I can't see the end of the shift lever.

[Jason Edge]

Kurt, No, 1964 Cadillacs with the Hydramatics (Series 62, 75 Series, Commercial Chassis) still used the long chrome caps with black inlays. Those with THM had the colored cap. It was explained that the different, thicker cap was sort of an indicator to the driver that it was a different shift pattern... or something along those lines. 

[Kurt]

Well I'll be darned! I learn something new every day.

[Jason Edge]

OK. Here is the how they express it in the 1964 Dealer Data Book. I am sure it is in the Spec Manual and maybe in the owners manual:
