Air conditioning recharge port 98 Mont. Sport

I have searched on this site, but cannot find any answers. My wifes a/c feels like it could use a boost of refrigerant, which I have done on many a car w/ good resuslts.

I looked under the hood and can't see any ports to hook up the refrigerant can. I know there has to be one somewhere....

can someone point me in the right direction please.

Thank You

They are hiding under the air intake duct at the right front corner of the engine bay, remove 2 bolts that secure the duct and carefully pry it from the filter box. You should see the ports.
