H3RESQ Posted September 4, 2013 Share Posted September 4, 2013 This is a XJ question, but considering the amount of swaps done here thought I would ask. I was told that in the factory wiring there is the ability to add a "idle up" button to the center console. Heard it was wired into harness because of police vehicles. (maybe specific to 97 and newer) I'm considering this for both my "99" MJ and my 01 XJ. Basically what it is suppose to do is when you hit the button the idle goes up 400-500 rpm. I just think if its true it would be a great thing for winch sitiuations, night wheeling situations, setting up camp in dark using vehicle lighting to see etc. Anyone know about this?

onlyinajeep726 Posted September 4, 2013 Share Posted September 4, 2013 Yes, this is possible and it's called an "Extended Idle Switch". You are correct about police XJ's using it. It was more common on the '97+ XJ's but can be found on some '93 - '96 XJ's as well, though it's rare.

ftpiercecracker1 Posted September 4, 2013 Share Posted September 4, 2013 This would be useful for me as well, because whenever I turn my a/c on my idle drops to 200rpms, I've even had it stall a few times. Link to comment Share on other sites More sharing options...

Compressor/clutch going bad? The ECU is supposed to bump the idle up about 200 rpms when the A/C is on to offset the strain of the compressor, but on a good working system, you would never notice that the rpm is higher because of the compressor's strain on the system. At least that's what I'm gathering from information I'm finding about extending the idle in Renix XJ's... Link to comment Share on other sites More sharing options...
ftpiercecracker1 Posted September 4, 2013 Share Posted September 4, 2013 If the compressor's clutch was going bad there wouldn't be a strain on the motor to begin with. No clutch = no strain. Right? :dunno: Link to comment Share on other sites More sharing options...

ftpiercecracker1 Posted September 4, 2013 Share Posted September 4, 2013 I dunno either, just got off of work and headed straight to the library to do homework. Aaany who, my a/c system is frankenstien system anyway. Condensor, thing in front of rad, and compressor are off of a late model Cherokee from a junkyard. Spun freely when I bought it, and the system was still fully pressurized when I took it apart. The dryer is the only new component on the whole system. I think a biggest issue is the fact that the guy I had "recharge" it, did a really s****y job. I was standing there helping/watching him do it and he only pulled a vacuum for like 30 seconds. :shake: I knew it wasn't right, but who am I to question an actual mechanic. :hijack:, BIG time. :D Link to comment Share on other sites More sharing options...

carnuck Posted September 5, 2013 Share Posted September 5, 2013 My '86 had the connector on the PS hose for that. You might find it near there. Link to comment Share on other sites More sharing options...

carnuck Posted September 8, 2013 Share Posted September 8, 2013 2.8, diesel and '87 4.0L ones had it (not hooked up on the 6) Link to comment Share on other sites More sharing options...
