Default '64 Coupe Question

The first '64 coupe I owned in the early 70's was a pretty plain 300hp car. It had an exhaust fan behind the driver's seat that was activated by a vent pull **** below the dash. The coupe I now own is a factory A/C car and there is no evidence of a like exhaust fan. Was the fan installed only on non-A/C coupes or might it have been removed from my current car at some point? Thanks in advance for your replies.

Greg, I was not previously aware of this fact, but this from Michael Antonick's "Corvette Black Book":

"A fan was added to the rear area of the 1964 coupes to assist with the ventilation problem common to 1963 models. The operating switch for the three-speed fan is located under the driver side dash. The external opening s for the vent are located on the side of the roof, between the door and rear window. The driver's side is functional. The passenger side is not."

On later cars with AC, the manual kick panel vents are omitted, relying on the AC blower to provide ventilation. On 68-72 cars, for example, the rear "Astroventilation" door openings are permanently sealed when the car has AC. I am not knowledgeable about midyears, but I expect that same reasoning originated on 64s, and that would explain the absence of a ventilation fan on your AC coupe.

Maybe someone with midyear experience will contribute some knowledge.

Greg,
Back in the late 70's I had a '64 Coupe with factory A/C & I'm FAIRLY certain it had both. I may be having one of those senior moments but I vaguely recall taking out the rear fan & cleaning/checking it while I had the interior out.
Hopefully, others will confirm or unconfirm this.
Regards, Bob L.

Had a 64 AC coupe last year and it had the fan in the rear, remember it well as I turned it on and it refused to shut off, had to remove the carpet panel and pull the cable to the off position.

All 64 and 65 Coupes had the interior exhaust fan, with the outlet behind the driver, regardless of being an AC car or not. They were notoriously unreliable and ineffective and were a good source of aggravating rattles & squeaks. I removed the entire assembly from my 64 AC Coupe years ago when replacing the carpet.

My 1965 factory air coupe, has the exhaust fan in the left side roof pillar. It was discontinued for the 1966 coupes.

Default 64-65 coupe rear Ventilation!

According to my owners manual the rear vent **** is far left or almost under the rotational light switch. (also won't work if the heater is on, according again the owners manual.) Pulling the cable kmob open the motor value. 1/3 half and full open. So what turns the motor electrically on?

Do you twist the **** clock wise? please let me know as this rear vent. thing has been driving me crazy for months and no one seem to have the answer. Hell you can't even Google it!

My '64 with a/c has the fan. Owned the car since 1970.

That's great but this has noting to do with A/C!
I did consult reputable Corvette Mechanic and he gave me the answer I'v been looking for!
A/C heater Temp and Def. are all ***** up front above the radio *****! in the front!

This **** is far left under the rotational light switch!
pull out and twist clockwise! Motor comes on.(in the back)..you can hear it and to test it
you can hold toilet paper up to the driver-side gills on the B-Post and watch it flutter!

Air in the back of the coupe or luggage area goes through small gabs in the rear carpet and is
sucked into the motor which then blows it out the gills! Great back in the days when people smoked!

and that's how it's done!
