92 wrangler ac drop?

I am doing a heater core on my 92 wrangler. I have under dash a/c and I am stuck on how to drop it out the way to get the heater core out. Is there anyway I can just unbolt it and slid it out the way without disconnecting any of the a/c lines? Thanks Brandon.

The common way as far as i know if to have the refrigerant evacuated of the system first. I do not suggest continuing working on a charged system while under the dash unless you have instructions they you feel very sure of. Because one it is a large fine to knowingly release refrigerant into the atmosphere, and two refrgerant like to raise and wents poorly, if your laying under the dash and the refrigerant starts to leak it will collect and be trapped in the the high points of the dash, the car, and the garge roof.

Any good A/C shop should be able to evacuate the refrigerant and disable the compressor while you R&R the heater core. Then refill it with fresh refrigerant and oil.

The AC unit is held on by 4 bolts. You don't need to evacuate the system, just remove the four bolts from the bottom of the dashpanel and slide it off the latch next to the steering column. This should give you enough access to remove the heater core, it is still a pain.
