iat sensor on a 97 blazer and what does it do

You should have this verified but the freon is probably HFC134.
Yes
Connect a freon gauge and tank to the low side ac port of the 97 DeVille. With the engine running and the ac on high, open the freon valve. Shut the valve when the ac gauge reads full.
