Doesn't the control have a setting for MAX air and another setting for
"NORMAL or Just AC? MAX is the recirc setting.

Hmm, sounds like it might be an aftermarket unit. Some of them look
close to factory but not quite. I don't think Chevy has built an AC
unit that did not have a recirc setting since the 60's. Is your auto
temp control? If so, that might not give you manual control.

My Dad's 90 GMC Sierra is the same way. No max setting. Just A/C on
and off. It came this way from the factory.

Its not aftermarket as Bob stated, it came from the factory that
way...
I do know the trucks history and it never has been replaced...

Maybe it was controlled by the full COLD setting at of the temp
control. It's possible that setting that all the way to cold put it
on recirc. You'd be able to tell from the sound of the fan. I know
GM used to have a vacuum switch at the full COLD temp position that
shut off the hot water flow to the heater core. But they also had a
recirc position too on the car I had that was like that (69 Pontiac).

"max" air is re-circ.

If no "max" setting, then moving the temp control all the way to cold will
re-circ. Sounds like a dealer added A/C to me.

No no... thats the way they came until 93-94. I'm not sure if the trucks
have rec. air... AC units have the electronic control pannel, where as the
non ac units use the old tryed and true cable pullys. Im not sure, but i think
temp control set to full cold puts the system into rec. air mode.

Easy enough to test. If it goes into recirc you'll here the extra
noise from the fan.

Putting the setting to full cold, there is no change in the fan at
all. My Dad's 90 Sierra came from the factory without a Max or Rec
setting. Now my friend's 94 Silverado did have a Max setting. My Dad's
unit is not an add in. The truck was purchased in Texas and came from
the factory the way it is.

Any chance of a picture of the control head? I'm sure you are
correct, it's just hard to believe GM cheaped out to the point were
they actually didn't even include a recirc setting. How do you know
it is a factory AC? Was it purchased new with window sticker? I
don't know if it still happens but quite a few years ago dealers often
made extra profit by ordering vehicles, esp trucks, without AC and
then adding it themselves.
 >> Stay informed about: 89 air cond switch 

It's obvious now, that it was definitely a dealer add on.

All I can say is my 87 chevy truck had and my 91 chevy truck has a max air
setting, and that
straddles your dad's truck production date.. Both of these are Tahoe
editions, both manual air, not climate control. Controls are verticle on the
right side of the dash. The 93 Aastro van I drove at my last employer was
the same way.
So dwas my mom's 90 Corsica. and the 88 Celebrity wagon it replaced.
Just because you bought the truck new from a dealer does not mean it does
not have dealer
add on air. Especially in Texas.
