1980 Corvette owners: HELP
I guess you could say I just repaired/overhauled my center bezel and gauges. I pulled all out including the shifter bezel. I did numerous things and all is back together now. BUT, I don't remember if what I am hearing now did it before the work. Now, when I turn the ignition key and stop just before cranking, not all the way, stopping at the last position where the lights and radio comes on, I hear like the fan running. If I leave it there it sounds like its running on a low speed. All switches are off. Is this normal? Does anyone's do the same? I just don't remember if it did it or not before the work.

Just be glad your fan speed selector switch is properly working! Lol Yea... That is normal... Something about constant recirculating air...
My switch however gives me full, or off... Not sure yet if I want to 'fix' it... Lol. It was working,. Then stopped.. But I still get full fan or off... And kinda enjoy that at the moment...

The engine is not running:
Just wanting to make sure. Also that my message was clear.
To be clear. The engine has not been started. I hear this with the key turned on just before the starting position..??

You are turning the Key to the Run position. When its in the Run position everything is well "Running ". Turning the Key further engages the Starter Motor, but only as long as You are holding it, its spring loaded so as soon as You are done with the starter motor it returns to the Run position, where hopefully everything including the Fan are Running.

It's your heater fan blower motor kicking on at whatever speed you have the switch set at when the key is turned to the 'run ' position...
If your electric fan blower motor, is blowing air inside the cab(not the cooling fan at the radiator) then this is normal... If it's making any obscene noises like the bearing is going out... They are super easy, and cheap to replace($14.99 for a c3 blower motor )... If you are wanting MORE airflow, you can buy a c4 fan and find a c4 fan cage, modify an adapter to make up the difference in height , and get MORE airflow out of your vents ... There are threads here about doing just that.

Yep. Off=low... Although I did come across a mod here on the forums (I believe it involved bending or removing a contact point or two in the control module.) to make off=off. I'll have to look for it again as I see no reason for the fan (and mine is a bit noisy anyway) to run all the time. Likely draws more heat into the cabin; definitely not a feature I need!

Just for those who may stumble on this thread later. I removed the brown wire from the connector on top of the heater/ac box and taped it up. The wire connector will slide out of the plastic plug with the use of a small flat-head screwdriver. Took 5 seconds, and now "off" is actually off- low, med and high are unaffected. I've never even driven my car with t-tops on and windows up, so I'm not worried about cabin ventilation issues. I'm more concerned with limiting engine heat inflow...
One of these days I'll get the AC fixed!

On an '80 the dark brown wire (rearmost) is the lead for the "off but still running on low" speed. Using a small flathead screwdriver you can remove the wire from the connector seat... Now off is truly off, and all the other fan speeds are unaffected.
It's a quick change that can easily be reversed. Some think it's a bad idea because it means no continuous fresh air flow into the cabin, but my Vette is a fair-weather toy, and I'll never be driving it with tops on and windows up (especially here in hot E. TX). It's also a good idea to quickly pull the whole connector and clean up the contact points for all wires. Mine had light rust and grunge...

The connector is on the AC/box at the firewall- passenger side.
