My ac and heat air is not blowing out very much air any more what is the reason?

What is your question?

What would cause my ac and heat air to not blow out that much air?

What makes this problem better or worse?

Nothing makes it worse or better it just doesn't blow out much cold or hot air anymore

How long has your 1996 Nissan Maxima had this problem?

For months now need to get it fixed before winter geys here
