97 Hardbody 2.4 AC issues, need help

[Hankster1958]

OK. New to Nissans!! Love this little truck so far.. BUT! I need to get the AC running. Got this from my Brother in law. He said, the AC was leaking freon, and they had to add some periodically, but it must have ran out. He;s NOT very mechanically inclined....so I jumped in. Obviously the AC didn't work. So, I tried pushing the AC button, no light, Compressor does not kick on. Fuse for AC, ok. Switched relays, RELAY was OK. Found low pressure switch behind overflow bottle, Jumped it. NO AC, compressor does not come on. Had switch in "ON" position, just in case. NOW, if I run 12V directly to the Compressor clutch, it kicks on, and the AC WORKS! low pressure line get cold, HP line HOT.. Truck cab cools down fast.... Pressure on gauge of fill up bottle of 134 looks good/in proper range!! WHAT, am I missing??? I took out the AC on switch from the dash, and used Ohm meter on it... it reads different, when "on" and when "off" so it appears to be ok as well. What ELSE, can be keeping the AC, from working???? And more important, WHERE is it located???? Thanks!

Never Mind!! Nissans are wired WEIRD! Who would have thought, the CIGARETTE LIGHTER fuse (don't use it) would power the AC SWITCH?!?!?! But reading several other posts here..electrical issues... got me to thinking.. and looking... and whadda ya know!! All is well.. wired goofy, but i love this truck!! LOL!!

had the same problem years ago, but mine was blowing cig fuses because it was rusted.

Hey, thanks for that info!! If that fuse pops again, I'll know where to start look right off. I've only had this truck a month, so no telling how long, that fuse had been out, it sat a while over there, before we got it. Now, I'll have to focus on quieting down those ticky lifters..... LOL!!
