Re: 1966 C20 deluxe heater controls face color fawn or black?

Thanks for chiming in OEM. I have not seen as many A/C trucks as you all, but in the pics above is it just my imagination on the darker bezel?


Do you have any literature that shows a different part number for the 66 only components?

Re: 1966 C20 deluxe heater controls face color fawn or black?

Heater controls : 3840038 is the number for 1964-1965 , it changed in 1966 to 3885187 for heater controls. Then in 1967 3885187 became 1964-1966 as GM grouped these together for "Service parts". Changes like color were not always well defined in parts books but the numbers are if you dig deeper. This IS the reason for Parts History books , to see when changes were made.

The AC Dash Bezel: 3840708 is the 1964-1965 Fawn bezel. Interestingly the DO list a different Production line Bezel as 1965 3866140 which is light fawn , seems as 1965 late AC was installed on the line . 1966 Dark Fawn AC Dash bezel is 3885191 and is specific number because it was cast in a different color.

The N.S.S. reference you see Tony , my guess is your using a much later print dated parts book. The older books show these numbers in the drawings also.

Air Conditioning Accessory kits : 1964 kit for 283 truck 985892 , 1965 986269 , 1966 986441.These are all "Basic Kit 283" accessory numbers , NONE of the part numbers overlap to other years. Each year had some small change or parts added or deleted. Theres a different "KIT" number for each engine also.

1966K10 , your dash bezel , my best guess , dealer installed something he had on the shelf OR your bezel was replaced some time in its life. Your AC could have been added AFTER your truck was bought new , like a year or two later. All are possibility's. Theres NO WAY of knowing that this bezel was installed in your truck when it was New without original owners adding that fact or tracing the trucks owner and service history. If you take your underdash unit off the firewall and out of the dash , there are inspection stickers that may give you a hint to the date of your kit but thats a long shot that thats still glued in place.

That heater control is from a GMC . All the Chevrolet deluxe heater controls 64-66 have the bowties on the lens. Being black ? Ive only seen a couple NOS Black heater controls which usually meant "Paint as required" was next to the part number in the books. Or somebody painted that ?

Re: 1966 C20 deluxe heater controls face color fawn or black?

Thanks so much for taking the time to check your literature.

Just a few questions, my parts book is the 46-72 manual (same as the GMWIKI) and has left me guessing multiple times, it sounds like a part history would help make sense of things. What does N.S.S. mean? I guessed Not Sold Separately.

One thing I noticed while looking at a bunch of pics of A/C parts is fawn overspray on the diverter boxe and inside the main vent (bezel not installed at time of paint). If these units were installed on the line did they do this before the dash was painted?

There are several printings of these books, look on your cover for something like " Effective May,1979" That book I have also and is a "good" source but you have to keep in mind its a general description of whats what. Having a 1966 print date book will give you a better reference to exact numbers but even then , numbers were superseded by years and changes. Thats why , no one book will give you a complete answer. GM Parts WIKI is , Okay , But they do not have many of the parts books , yet , that were printed by Chevrolet . The part numbers I posted came from a 1966 dated parts book AND a parts history book , that WIKI does not have.

N.S.S. , Not Serviced Separately , THAT has to do with the timing of the printing and surplus of parts. Using the 1979 or later books as an example gets you that, as the Bezel alone was not available at that time (1979) but the Assembly with the vent balls might have been ( I have not researched that). In 1966 you could order any single part yet. Parts History books will also tell you WHEN a part number was discontinued or changed. The numbers I posted are just of the fawn bezels , not with the chrome vents. That would have a different part number as an assembly.

All the interior paint was done before assembly , your truck, being that the AC was not available on K series, was either assemble with the AC AFTER it rolled off the assembly line in a side section of the building OR at the dealership. If your seeing paint on parts now , maybe somebody took those AIR parts out of another truck and added this option later in its life ? OR the dash was repainted at some point ? They should NOT have overspray.

Re: 1966 C20 deluxe heater controls face color fawn or black?

All evidence points to dealer install and my parts dont have any overspray. Of course I cannot find the thread where the PO claimed factory install with pics of the boxes/vents.

I know Im probably irritating but I love the minutia. Ive been heavily into VW for years and love to investigate all the wierd special order or various export options or factory specific details.

Im not trying to make my burb something its not as someone told me, I just like to know all I can and the older I get the more time I have to satisfy my thirst for knowledge.

Thanks again for all your input!!!

Re: 1966 C20 deluxe heater controls face color fawn or black?

Not irritating at all Tony . These details are important to just a few .

Heres an NOS light fawn 1964 1965 Dash bezel with the part number molded into the plastic along with the white painted insert bowtie.





Heres a 1966 AC Dash bezel with the different part number. Plastic you can see was molded in the darker fawn.





And heres the NOS AC unit 985790 Basic 1964 kit, notice the date on the inspection sticker , December 30 1963 for the 1964 production year.
