Just wanted to update and say I got the a/c going

I want to thank everyone who responded to my post and gave me their advice. After the a/c suddenly stopped working. I fooled around with the truck for almost a week. I knew it had to be something electrical. I studied the factory service manual and I came to the conclusion it was the push button a/c / heat climate control had went out. I ordered a used one off of ebay last week and it came in Sat. while I wasn't home. I plugged the new unit in yesterday and it would not work just like my old one. So, I just said I wasted more money b/c I had already bought two new relays.

 

Well I was going to give up. But something made me give it one last try this morning. I studied the fsm a little more and printed out the pages I thought would help. All I had for testing anything electrical was a 12 volt test light. Well I spent most of the day trouble shooting and finally got the climate control I ordered to come on and work. But it would still not engage the a/c clutch. Well the last part was luck. I was pressing on the fuse box to make sure everything was tight. Then there was some clicking. I pressed harder on the clicking noise and the a/c started working. The ecm fuse was not blown but somehow it must have been loose or something. My rpm went back to normal and my a/c started working. I started the truck several times and each time it worked. Drove it around the block and everything electrical was working and the a/c was ice cold again.

 

I have either fixed the problem or have began a mess of electrical headaches to come. Hopefully I fixed it.

 

Just wanted to update and thank everyone.

Well that's great, hopefully that's the end of the problem and now you know how to fix it if it does it again.

Nice but of luck there! Good on ya for working at it all day, I would have given up at about the three hour mark and gone for a beer!!

Thanks. I was just thinking my pathfinder is 20 years old and the electrical stuff is not that bad, but it still gives me fits. I also have a 2008 Pathfinder. It has so many electrical gadgets that I hardly ever use, and you know sooner or later something is going to tear up. I don't think I could handle anything like that.

Just think, the Delorean was a pretty old car yet it could still go back to the future. Just think Doc Brown - "1.21 GIGAWATTS!!!" *falls over*

I've seen fuses get corrosion on their contacts and not conduct. I recommend you take a few minutes to pull the fuses and look to make sure they are clean.

Hint: Do it one at a time...
