Did you take a look underneath? Is the condenser kicking on, do you hear the clutch working. If you've done that I'd say get a can and try to "recharge" it.

 

A few years ago, my A/C stopped blowing cold. Turned out there was a bad temp sensor under the dash that had to be replaced.

 

Think I saw a utube video where there's a small part that's is prone to breakage an nissan doesn't even sell the part by itself u gotta buy the whole box an take apart quite a bit if ur dash. Ill look 4 the vid an get back 2 ya.

Never mind he said the heater wasn't working. The vid is titled "nissan Titan nightmare."

I am pretty sure the compressor is not running, been raining here past couple days and I havent had the chance to crawl underneath the truck. But I did buy one of the gages you get with the charging kit and it shows up in the red, which according to the instructions, means the compressor isnt kicking on.

 

Then when it quits pouring I'd check and make sure everything is attached

 

Sounds like you have a refrigerant leak. You need to find the leak, replace whatever is leaking, pull a good vacuum on the system and then charge it back up.
I had this same prob but I found my leak pretty easy. It was the high side hose that goes from the compressor to the condenser coil by the radiator. It has a metal elbow that rubbed on the washer fluid reservoir and that was it. The hose cost me $100 then about $150 to have it replaced, vacuumed down and charged. Been working great for 2 weeks so far.
