Blower motor double grd. connection

[John M.]

The AIM manual shows 2 connections on the blower motor one is a grd where a double black should go. My blower motor does not have a blade connection for the grd. is it not use on a 67 AC car? Thanks

Re: Blower motor double grd. connection

John, generally there is a brass male spad connector that attachs to one of the bolts on the blower motor.

Re: Blower motor double grd. connection

yeah thats what the AIM shows however my setup only has one for the Purple/Filter no signs of any damage or one ever being on it. I'm thinking since its a AC car it might not be used????

Re: Blower motor double grd. connection

John, the filter goes in-line with the power wire to blower, and the brass spade is used for the ground. I hope that This is what your explaining.

Check the radio option in your AIM - you should see the capacitor added to the motor for that option if its not radio delete.
Do not believe (at least for 64) any capacitors were added however by 67 it could have been added. Just another place to check.

Re: Blower motor double grd. connection

so there should only be one brass spade? I added one and mounted to the motor but now you have me thinking that was not correct. I'm really unsure what is correct.

John,

Check C60-E1, see “View B” in the bottom LH corner, it looks like the double black wire connects to what I’m guessing is an “L” shaped brass terminal, attached under one of the blower motor screws.

The ’67 P&A calls out GM 6402685 for “67 Corvette w/C.A.C. …………….. TERMINAL”, but I’m not sure if that is the “L” shaped brass terminal or not. Joe will know. The vendors use GM 1513228 brass terminal (see Paragon #13645 for example). The P&A says GM 1513228 was applicable for "ALL ALL", has a 39/64” O.L., shows a picture that looks like an “L” shaped terminal, and says it was replaced by GM 6401281 in August of 1967.

If you have John Hinckley’s slide presentation that used to be available for download on the TDB main page, there is a slide that shows this area of the car very well, but it is not a C60 car in his photo. The brass terminal in John’s slide is attached under the blower motor screw at about the four o’clock position, while the C60 terminal in the AIM (C60-E1) appears to attach under the blower motor screw at the two o’clock position.

If anyone knows, is that JH’s Marina blue ’67 convertible in the slide presentation photo?

Scott -

That particular photo (below) isn't my car, but mine looks exactly the same; the A/C setup uses the same in-line capacitor arrangement, and has a similar male spade for the black heater blower ground wire.

John,

The reason I asked about the picture is because I have a question. I realize now it's a '67 big block (no expansion tank), which means those hoses are called out on L36-A4, the same page as the GM 3841336 hose clip bolted to the inner fender (shown in the bottom LH corner of your photo). Dobbins shows a picture on p. 238 (Vette Vues 63-67 Fact Book) of the 1966-67 RH inner fender with the new-for-1966 molded indentations, saying the molded indentation "...was used with a clamp to hold heater hoses in place on big block and air conditioned Corvettes. It had no function on other cars...".

The indentations in the RH inner fender were the same for all 1967 production (SB and BB), yet the clamp location is 5.50" back from the dust shield and 7.25" down from the rain gutter on the big block (L36-A4) while it's 3.50" back from the dust shield and 5.25" down from the rain gutter on the small block w/C60 (UPC C60-D3).


My question is:

1) shouldn't the upper of the two indentations be visible in your photo, with the upper hose seated into the indentation?

2) doesn't the location of the indentations in the RH inner fender skirt determine where the clip has to go? Even if the GM 3841336 Clip is large enough to span the height of the double indentation in the RH inner fender, don't the indentations determine the clip installation distance down from the rain gutter? That is, shouldn't it be either 5.25" or 7.25" down from the rain gutter, but how could it be both, when the indentations are in the same position regardless?

I have been trying to figure out the correct hose clip configuration (location and quantity) for a '67 with L79 and C60 for about 3 years now, and every piece of information I can find on the subject conflicts with every other piece of information.

Do you have a photo of an original '67 small block with C60 that clearly shows the clip (or two clips?) and their location(s)?

Scott -

Wayne Womble would be more familiar with the nuances of the inner fender configuration than I am; he has dealt with them hands-on for years, and I haven't.

There are two photos below of a restored '67 L-79 with C60 from my files - I took them ten years ago, and don't recall where or whose car it was.

Re: Blower motor double grd. connection

John H.'s photo was from a '67 BB I worked on last year. John helped me here on the TDB several times trying to locate clips and things when I was working on it. I always put lots of photos on here for future reference and glad to see others can benefit......as long as they're accurate.

Here are a few photos when the engine was out. I never gave much thought about the indentations in the inner fender. Good info.

And a few more of the blower connections for John M.
