I have a question about the air conditioner. It seems to make a hissing noise at low settings and doesn't blow out cool air at all. The temperature is usually luke warm.

Any suggestions on possible fix?

Hi

What year is your X?

If the air isnt cold, then its probably cause your freon, or whatever they call it nowadays, is low or depleated. This is particularly the case if you notice that your AC compressor stops clicking on and off.

Anyways, if you're like me & love the AC, bring it in, and have a tech look at it.

Having a problem with air conditioner in 2003 xterra that: when vehicle is travelling on open highway the a/c is fine, but when the vehicle is going, say 30 mph, the a/c unit blows out warm to hot air. Anyone have a suggestion for what the problem could be? Any help will be appreciated.
