Re: '99 Pathfinder, Replaced AC System, Comp. Clutch Won't Engage

Well, I just got my weekend back, thanks Detroit!!! Pulled the negative off the battery for around 30 minutes, hooked it back up and the clutch engaged properly :D My AC controls only go down to 65 degrees, but it was blowing mid 40's straight out of the vents. You and John saved me from months of s...

Re: '99 Pathfinder, Replaced AC System, Comp. Clutch Won't Engage

I loaded the rest of the Freon into the system, blowing super-cold now, here's my gauges running the air at it's coldest setting: https://i.postimg.cc/JndDM4BP/IMG-5640.jpg unfortunately, problem still remains, clutch won't engage without shorting the relay. A little more backstory that might give s...

Re: '99 Pathfinder, Replaced AC System, Comp. Clutch Won't Engage

Getting ready to head out and fill now. There is one other lingering question that's been worrying me. As I stated in the original post, the compressor I have (SPAM LINK) came with 6.1oz of PAG; since my system calls for 6.8oz of PAG and I'm installing all new components, I drained 2.5oz out (I coul...

Re: '99 Pathfinder, Replaced AC System, Comp. Clutch Won't Engage

My apologies, I did use the yellow hose for the Freon (been a long day), and just opened the Lo/blue to fill. I'm thinking I should just put the rest of the second can in. Full @ 1.45lbs would be 23.2oz, so it sounds like I won't be overfilling. Definitely agree on the PITA that is self-sealing cans...

Re: '99 Pathfinder, Replaced AC System, Comp. Clutch Won't Engage

Thanks for the quick response John! To refill after evacuating, I attached the refrigerant to the low side blue hose and opened it up with the clutch engaged. The sticker said it takes 1.34lbs +- .11lbs, so I planned to add 22oz. The cans I am using (https://www.amazon.com/Chemours-Refrigerant-Freon...

'99 Pathfinder, Replaced AC System, Comp. Clutch Won't Engage

Hi, I've spent all today troubleshooting this AC problem. Yesterday I replaced the entire AC system on my '99 Pathfinder; compressor, radiator, evaporator, condenser, and receiver/dryer, AC lines are the only things I didn't replace (but I did evacuate them). Pulled a -30psi vacuum that held for ove...
