THANK YOU THANK YOU THANK YOU. This post was right on. After spending over $200 at the repair shop, they told me I needed to spend another $650. After finding your post, I got the part, followed the directions and presto, COLD AC!!Thanks for posting.
I had this same AC problem with my 2000 Xterra about 4 years ago. Spent lots of money at other places before finally taking it to Nissan where they replaced this sensor. Now the problem is back again. Has this problem returned for anyone else? Just wondering how long this sensor generally last and if I can look forward to spending that kind of money every 4 years to replace it.
