i have read around that you can change you ac parts out and put on an on board air system. my ac dosent work and in chicago i would only use it 3 months out of the year really dont need it and would rather spend the money on something to help the jeep. so i am looking for what you guys have on here for this bc i cant really find anything on it.

 

this is a pretty good read.

i think this one is a little better and after i posted this i went outside to see if the compressor is working and it dosent work. so off to the junkyard

did you jumper the ac clutch? at low or too high pressure the clutch wont cycle.

 

this is by far the best one i have seen done so far...

X2 Thats the one I used.

 

i just turned on the ac in the car and my stepdad said that i shouldnt have to jump it but i think my ac system is dry so i will have to jump it to see if it works.

just take the hot wire and touch the battery right ?

 

i like this one too but not with the front and rear plugins too many hoses to tear off with something. i think i am going to do a little of both of the last to write ups

 

mine is right in my build thread vvv

 

If you are going to the junkyard, you might as well try to find a York Compressor.

It is better than a Sanden compressor. With a York, you only need to remove oil from the air it compresses and add it back to the compressor's crankcase. (at a lower pressure, like 5 lbs.


A Sanden compressor needs to have oil added to the intake air, and removed from the compressed air.

 

The york is undoubtedly the better compressor but requires much more work to install.

If you don't want to put all the time into the fab work, a better option to save you from having to have a consistent flow of oil into the intake is to convert the sanden pump to grease lubrication.

To do this you need to:
Disassemble the sanden pump,
Clean all the oil out of the crank case,
Block the 2 oil passageways that run from the head/valve plate into the crank case,
Pack the crank case bearings and the orbital ball with grease, and add sufficient grease in the crank case its self,
Reassemble,
There is a plug on the side of the crank case that is used to add oil to the original system, replace that plug with a breather of some sort, I use a small Spectre breather. When I feel it is necessary to add grease I just remove the breather, install a grease zerk, add grease, reinstall breather

The only word of caution is be careful when separating the head and valve plate from the crank case as the gaskets can tear. You can buy new gaskets though, just difficult to source.

 

most if not all york compressors you find at a junk yard will not be set up for a serpentine belt.

 

Yea, but you can purchase a new clutch kit with the right pulley, but that just adds additional cost. I think they're $100+

 

yeah i am trying to go the cheaper way for this but still spend some money but not were i dont need it

 

ok went back out today to see if i could get the ac clutch to go and i dont think i am getting power to it i light tested it and the fuse is fine, i think it may be the plug before the wires connect to the ac compressor any ideas
