Gas and Air conditioner question on 1997 Nissan Maxima

Does the 1997 Maxima GLE take regular or premium gasoline?

Also, I have noticed a problem with the air conditioner not working. No air blows out of the front vent, although you can hear the air conditioner itself operating.

Could this be a compressor problem?

You can use regular 87 octane in your Maxima. I've been using regular in my Pathfinder since new in 2001, and have seen nary a problem.

I'm not sure about the AC issue. Sorry! Hopefully, someone else can answer that question.
