'67 Resistor Assembly on Blower/Evap Asm

[Kirk M.]

Was continuing to detail and clean my engine bay and removed the "black plate" that represents the resistor assembly on the blower/evaporator assembly. Removed the two screws and lifted out the assembly. I thought it had been erroneously painted black, but when I went to clean it, I found out it was "plastic" and not painted metal. After a good cleaning of all parts here is what I found stamped into the upper surface "INDAK" with a "2" and "3" next two two of the plugs and a part number "3843168". One of the prongs hanging off the inner surface has "INDAK" over "PAT. PEND" stamped on it. Not sure what any of it means, but thought I would share. Interesting what appears after a little cleaning.

Kirk -- thanks for sharing your discovery. I've had my two '65s for 28 and 20 years, and am STILL discovering stuff every day, thanks to this board and NCRS publications, [and eBay, heh heh].

Here's my current resistor on my C60. It's # 3929048 which I bought to replace the original (?) shown on left -- the connectors dislodged from the fiber plate, but coils are still good. This part # replaced the # 3843168 in July of 1968, for use on all '63-68 A/C cars.

Note mine (early Nov '64 car) does not have a part # stamped. Look closely and you can see the terminals numbered 1, 2 and 3. The INDAK is flipped 180 degrees from your example and my newer resistor.

Just little details that makes this hobby entertaining.

Indak made millions of heater and A/C resistors and blower switches for GM in the 60's-70's, and they were Chevrolet's sole supplier for those items.

That would be it dead-on! Interesting. Does INDAK stand for something or is that just the name of the company?

It's the name of the company.
