heater control swap

[Snag]

We're working on my neighbor's 1995 Chevy truck , the heater/ac
control module is shot . His truck doesn't have rear window defogger ,
the only available new control is only available with the button for
rear defog ... I'm wondering if that unit just has an extra pin or two
in the connector , and if it will swap into his truck that doesn't have
that option . Anybody know ?

I would venture to guess that it would work. Chevy probably wanted to
make it simple off the line. Sometimes the rear window defrost in
certain cars was a dealer installed option. Hope it works out.
