YJ AC systems from Jeep Air?

While waiting around for my block to be machined for my v8 swap, I've been tossing around the idea of building an air conditioner system since my 350 has an ac compressor and bracket. I'm doing a lot of dash wiring and have it apart for the v8 swap already so it is tempting if I can make the scratch and buy it without the lady finding out. Found an entire ac system minus ac compressor and bracket that doesn't look to bad. Anyone use Jeep Air after market AC's? Here's a link of what I'm thinking: https://jeepair.com/1987-1995-yj-wra...ompressor.html

Yeah, that's about what every jeep before the TJ runs. Same as my original dealer installed A/C. It keeps your knees cold, but that's about as far as the cold makes it on a hot summer day. It does slightly better with the full factory carpeting to insulate the cab a bit better.

That's what I was afraid of. AC sounds very nice since I've been living in southern california again. Just want some way to get cool when I'm stuck at a stop light in summer...

The Jeep A/C system is marginal at best, "factory" or aftermarket.
You might make a trip through Pick & Pay to see if you could find a later model underdash unit that you could shoehorn into your Jeep. I would start by looking at GM cars or trucks in order to keep the hoses and fittings that should mate up to your compressor. The Jeep heater system is pretty simple. The one problem that I can think of is that many later model HVAC systems are vacuum controlled. You may be able to adapt the Jeep cables to a different system.

If you do this, PLEASE post pics. I'm sure that there are plenty of YJ drivers that would like a more efficient A/C system. (Plus you will be getting rid of the 20+ year old heater core that is ready to pop a leak.)

Good Luck, L.M.

I replaced my heater core 1 year ago already lol. I'm thinking since my brother wrecked his 99 xj last december and already took everything he wanted on it for his new xj, I'm going to try and retro fit the dash/hvac/steering column and wheel into my jeep.

Jeep air is the oem manufacturer for yj ac. If installed properly, an functioning correctly the factory yj a/c really works pretty good . My 91 yj never had air, but was built with all the a/c wiring and connectors in the harness. I installed a used a/c that I refurbished in it, and in the hot and humid summers here it does better than expected.

That's what I use mine for - giving me a little cool air at a stop light, and it's hot here in Central Texas.

The vents are low, and the volume of air isn't great. But the unit that I have does blow cold.

One caveat - the underdash unit gets in the way of a lot of maintenance. Things like dropping the steering column, wiring, etc, is MUCH more difficult with the AC unit in the way.

For $600 something, the bolt in stuff doesn't seem too bad. I guess I'm just going to give some more time and thought to see if I'm going to go through with it or not. I don't have carpet, just a monsterlined tub so I'm thinking of making many changes to the interior before.

Mine has it. I knocked off the drainage tube going through the firewall so I could put in a center pod speaker.

Other than that, I think it works pretty damn well tbh...works better to keep me cool than the heater does to keep me warm.

I had my top off the whole summer though...I think I turned my AC on once during that whole time just to make sure it still worked.

I'm probably just going to get the kit. Just have to find a way to swing that without my lady knowing.... She's not happy about how much my v8 swap is already costing....

the only thing that would be unique would be the evaporator console. that is the big black fan and housing that also shrouds the evaporator... the heater core is inside a seperate black housing that wont fit the evaporator, so you will need the jeepair part, or find one at a pick a part place.

the dryer, and condensor and hoses are all kinda off the shelf.. you need to match the fittings to the compressor though...make sure they are same types/size. and hose lengths.

the safety / hi-low switches are all accessable thru napa or other auto parts store...

the big issue will be the brackets and mounting accessories for the compressor...

thats where Im at right now... I have to figure out the mounting system and whether or not I need another tensioner/idler pulley

I have the OEM?, a/c in my YJ and I did change it over to 134A, in the Hot Muggy summer down here in Louisiana it's cool {not cold} inside but it's way better than not having anything.
