people with JeepAir AC kits...question

Where are you hooking the blue wire with the fuse attached to it to? I just hooked mine up to the fuse box under the dash, which I know is probably wrong. I figured it just needed power to run the blower and controls. Now the fuse in the fuse box keeps popping. Can I hook it straight to the battery or what? Just want to hear what others did. Thanks.

If it has an inline fuse I would say connect to a power source. Probably needs to be controlled by your ignition being turned on/off.

What would be a good ignition source?

Run it off your fuse box under the dash. Try hooking directly to battery and see what happens?

You can connect direct to the battery, but you'll need to turn the a/c unit off every time you shut your jeep off. Or deal with dead battery, unless you use a relay controlled by the ignition switch to control the power from the battery.

I wired it up to the CIG lighter figuring that would be enough but it popped that fuse too. My idle would drop to the first line above 0 rpm and felt like it was going to stall then the CIG fuse most likely blew, haven't looked yet.

What the hell is going on?

low idle,

there should be a part in the kit to boost the idle when the A/C is activated.

I would go straight to the supplier with these questions. If they are no help, call an a/c specialist. these parts are way too expensive to be guessing with.

most important, don't get in a big hurry, you'll be glad it's done properly.

if there are no a/c specialists around, I can recommend a couple

I did send them an email a couple weeks ago and haven't heard back. I wish there was a part to boost my idle but there isn't. I'll have to look for a specialist.

I would pull the power supply directly from the battery install a terminal block. fuse protected, then a control relay switched thru the ignition switch 1st and a/c control 2nd in series, and did they provide you with a solonoid to bump up the idol? there should be a spot to attach it just beside the main throttle cable assy.

Where is the battery terminal block? There is a 30 amp inline fuse on the wire already...no I didn't get a solenoid to boost my idle. Can I buy one in a store?

Also don't think CIG fuse blew because I still get power through the CIG lighter. The inline fuse looks ok too.I don't know what happened now.

the fuse for the lighter is to small to run the AC. you could tie into the fan for the heater, probably wouldn't be running both at the same time, but the best way would be off the battery with a relay triggered by a switched hot wire.

Might be the output to trigger the fan??? Fan should come on whenever the A/C compressor turns on...

i have a bunch of empty fuse slots in the box under the hood... my jeep didn't come with AC from the factory so i am missing the black AC relay. Can i just run the wire to one of the empty 2-prong fuse slots and put a 30 or 40 amp fuse in it?

i just tried this and it blew the 30A inline fuse on the wire. The idle of my engine will drop to 1rpm almost 0, like is is about to stall and then POP the fuse blows. This is starting to piss me off. any ideas?

If your blowing a 30A fuse, sounds like you have something wrong with your install. Too much freon in the system, or wired up wrong. The only things that should be drawing any power are the compressor clutch and the blower motor. The compressor clutch should only draw about 5-10 amps. The blower motor should be about 10-15 on high. I'd double check everything on your install. Just curious how did you charge the system if you can't keep the compressor running? If you charged it up without the compressor running you've more than likely over charged it and have the compressor locked up, that would explain bogging your engine down.

I forgot to mention that I installed it last summer and it was working fine until now After I installed it I brought it to an auto shop to vaccum and charged.

also i just bought a new battery during this past winter.

could my alternator be bad?

Not likely, with your jeep off you should be able to put a socket wrench on the nut on the front of the compressor and turn the compressor by hand. If not then chances are that the compressor is locked up which would still explain bogging your engine down, should not blow the fuse though. If your a/c worked last summer why are you asking where to hook the blue wire, the way your op sounds is that you're just doing a new install! The only things that should blow the fuse are, a shorted coil on the compressor clutch, a bad blower motor or a wire that has rubbed against metal and is shorted to ground.

this site has the instructions for the jeep air kit, but it sounds like you have another problem.

Compressor clutch is free.

I do have my CB and AC ground wires together... If that matters.

It decided to run properly without blowing the fuse but when the compressor kicks on the idle drops to 200rpms and when it kicks off it goes to normal.

The drop in rpm is to be expected, I'm going out on a limb here( going to ass-u-me) that you have a 2.5 engine ! And without the idle solonid to up the idle rpm will drop when compressor kicks on.

Yeah 2.5L forgot to mention that too lol.

Isn't the IAC basically the idle solenoid in a way?

good idea,

if you are not lucky, you could easily burn your jeep down.
