AC system removal

So I just brought home a 91 Cherokee 4.0. Really good condition for an all Florida Jeep. The A/C doesn't work. Fan blows good. I'm thinking of removing the A/C system to make a little more room for engine activities. Has anybody ever done this and did you have any issues removing it or after? I was told that the ultimate remedy to get it working again would be a complete system replacement. TIA

AC problems have to be diagnosed first, usually it is one problem. Most likely, it is easier to repair AC than remove components.
Only once I had to fix about 7 AC problems, but it was 84 Corvette. I installed heater valve from some Dodge.

I used to yank the AC out of any car that it did not work. Then I wised up and learned about AC. There is only one moving part: the compressor. It is the usual culprit. It is not hard to learn but the tools are the real answer. You simply cannot work on AC without a good set of gauges. Then a vacuum pump for removing moisture. A digital postal scale for adding the correct amount of freon. Everything else is just "O" rings.

This!

If I have to explain it, you probably won't understand anyway!

everything is pretty easy except evaporator replacement.
Did you start repairing house AC yet?

I have never had a house AC go bad. Noisy, but they work. Cars, always. So I got 609 certified for mobile systems.

Accumulator/drier system with an orifice tube, simple to fix. Expansion valve system with a drier, still easy, but can trick you. I don't remember what system they use on those ones.



I'd fix it. Nothing beats having A/C on a hot humid day.

Let us say every part of your AC is bad. The only part you need to drive your Jeep is compressor bearing. (about $15 and you can probably install it w/o removing compressor.

If you wanted to remove it, you can swap the compressor out for the AC Bypass pulley.

I would fix the AC.
