1965 a/c blower motor

Was the 65 A/C blower motor dated and should it have any other marks on it thanks Ralph

Ralph -- let me stick my neck out here and say "not (die-stamp) dated", unlike the non-air cars.

Here's a "spare" for my '65 air car; stamped 5044559. I tried to look on my original but too difficult to see as installed. I seem to recall that there might have been a yellow ink/paint (rubber) date stamp on my original, but I'd have to sort through many pictures to find it.

Re: 1965 a/c blower motor

My recollection is the first use of date code stamping on blower motors began in '65 with the '63 motors being a 1-year only design and the '64 motors simply having the assy PN stamped on them.

I'm pretty darn sure that's the case for the base blower, but I can't really testify to when the process of date code stamping was adopted for the A/C version of the fan assy.

Thanks Wayne and Jack for your response and help.

Ralph and Jack -- found the pic of my original '65 C60 blower motor off an early November '64 car, first day after the strike ended.

It has a yellow ink stamp "8" (space) "dash", "64".

This is only one example; can't speak to the changes throughout the C2 era.

I can't say when it started , but here are some pictures of my 66 A/C motor . In case it is tough to read it says; 12 65

Yeah, that stamped date code is what I'm used to seeing. The example of the earlier 65 A/C blower assy with its ink-stamped date code may be a rare birdie...

It might be a 'transition' part made after GM decided to date code the motor cases, but BEFORE the tooling was modified to physically stamp the motor case along with the Delco PN sequence.

One more ? in 65 is their a difference between an a/c blower motor and just a heater blower motor or are they same or a car with A/C have a slightly bigger motor thanks Ralph

Re: 1965 a/c blower motor

The PN stamped on the motor's flange refers to the blower ASSY number and not just the motor. The assy consisted of the motor and the squirrel cage fan. If I remember correctly, service carried the two items (motor and fan) separately.

The standard heater blower assy differed from the A/C version. The A/C motor had an extra circular hole in the case where a rubber hose/pipe connected. The hose/pipe carried cold air from the A/C plenum back to the motor to cool its armature and bearings...
