So in 64 the part number is 3849471. It does not come up on a search here or in google or in ebay. On ebay they do have a 3864600 which they say is correct for 65 to 67; it is an Indak switch and appears to have five terminals whereas the AIM only shows four in 64. I also see that some repros are available for C1 models. If I needed one for my 64 what would my options be? Since I don't see much in posts about this maybe they just don't fail often.

Re: Heater Cable and Fan Switch
Larry do you have a pic. of a 64 switch and cable length, I have one I believe its for a 64 used.New England chapter member, 63 Convert. 327/340- Chapter/Regional/national Top Flight, 72 coupe- chapter and regional Top Flight. -
Re: Heater Cable and Fan Switch
No...but I'll see if I can get one. Maybe you could send a pic of your switch and I'll do an "eyeball" versus the one still on the car. I might have somnething I can trade you.Comment

Re: Heater Cable and Fan Switch
I know the reproduction heater cable and fan switch, had to change the wiring configuration. The thing would work correctly using the orginal plug configuration. Par for the course for reproduction parts. BTY this was on a '66 with A/C.Comment

Re: Heater Cable and Fan Switch
I pulled a side panel on my car and looked at my switch. Whereas the AIM assembly drawing shows four terminals the wiring diagram shows five I think (it is not clear) and my car has five. Since the wiring diagram in the 64 AIM shows revised in July 65 it is fair to say that it is not the 64 chart and the colors are wrong. On my switch there is a 3-gang connector with wires of 1- black and black w/orange stripe, 2- black with yellow stripe, 3- black with light blue stripe. There there are two single delphi connectors both with brown. My switch looks just like the 65-67 version shown in the attached which is an ebay picture. Both ebay listings show patent numbers but are different. My switch shows pat pend. I think, based on Joe Lucia's input, any 64-67 switch will work and maybe the 63 also, as long as it looks the same and has the five terminals.
Thanks for the help. I know where I'm going with this now.Comment

Re: Heater Cable and Fan Switch
Edward...so I looked again just to be sure. My installed unit has five wiring tabs; you pic only shows four. interestingly, another person offered me an NOS unit with four. I guess these are for 63 or some other year. I checked for a wiring modification.....my five come out of the original wiring harness neatly. Thanks for your response.Comment

Re: Heater Cable and Fan Switch
Larry, if you have a Coupe, 64 -65 has the rear blower motor and I believe that switch is 5 terminal to accommodate it. Do you have a Coupe or a Convertible?Comment

Re: Heater Cable and Fan Switch
Since I don't have a correct 64 wiring chart (AIM is wrong) I can't really check this out but I doubt the cabin fan and heater fan are connected. The cabin fan only needs power and a ground. It has it's own resistors and speed switch. It operates irrespective of the heater fan switch position.Comment

Re: Heater Cable and Fan Switch
IIRC if a 64,65 coupe the feed for the rear cabin blower is fed through the heater blower switch. This disables the rear cabin blower if the heater fan is switched to any speed.
I'm not near my 64,65 books but I'm pretty sure this was the design intent.

Re: Heater Cable and Fan Switch
Thanks for confirming Dan.....
I found a few diagrams.. They're '65 but '64 should be similar. (I uploaded the jpgs both big and icon'd for future reference)
As you can see, the "14BRN" wire is the input to the rear blower. It is sourced from the Heater Blower switch and is only powered when the Heater is off. Note that in THIS POST John H mentions that the wiring to the blower resistor is reversed on some of the diagrams.
Here is the feed circuit diagram which also shows the rear blower..... Note the BRowN wire sourced at the lower left terminal of the Heater Blower switch.

Re: Heater Cable and Fan Switch
OK, thanks a lot. After looking at the 64 AIM again it really only shows a four tab switch. The posted diagram makes it clear and I verified it on my car/coupe. When the heater fan starts the cabin fan stops. It is interesting that this wire does not go through the main body connector.
One "might" surmise or "guess" that a four tab switch would be good on all roadsters and any coupe not 64/65. In any case I'll be looking for the five tab switch which I'm sure I'll find.Comment

Re: Heater Cable and Fan Switch
Larry,
Maybe the reason the cabin blower wiring for the coupe is not in the Rear Body Harness was economics. There are many variations of harnesses due to the backup light option and maybe thye didn't want to add more inventory complexity. However I'm not sure if there was adequate terminal space in the Body connector for more wires. If not, that could be a reason. I just looked up how many rear harness options there were in 64/65. Many shown HERE.
Also poking around the LIC site, it shows 4 different switches for 64/65. Unfortunately their descriptions are intermingled with confusion. If you need one I suggest a call to verify 5 terminal as they make no mention or photo of backside terminals in the photos or descriptions.
I think it's this one....
