It's 4.9L 1994 Jeep
We diagnose first
and fix next
in that order or go broke fast GUE$$ing endlessly.
ask how to do the tests using real shop tools you do not have?
this is only the beginning tests. I have posted them all here vast times.already./
all fuses test good?
BLower works on high, (dash hAVAC blower)
the dash AC lamp glows. AC turned on.
the engine bay, compressor clutch fully engaged and compressors spins
and belt to it not missing or slipping.
full stop, lots more to do . but, you need tools to go beyond here.
most 1994 this is long ago dead, not told history of HVAC.
i say get a shop to diagnose it, pay them.
like 99% do or more.
SOURCE: Airbag light indicator: Jeep Grand Cherokee 1997
there are many sensors and and each airbag have sensors so you will have to get it scanned to know where to start. just a note air bag parts can be very expensive so check out your local salvage yard. they can save you hundreds. good luck

look for Main A/C relay, look for fuses, or go to a/c shop and have gas check out, perhaps leaks, perhaps evaporator, perhaps condenser, but start for relay box on front passengers side, or fuses on same side

Testimonial: "thank you so much, that helps me out as lot"
If your vehicle
has an A/C drain hose, it will be located on the engine side of the
firewall, below where the two A/C lines go through the firewall.
NO: 24-18-94
GROUP: Heating & A/C
DATE: Nov. 18, 1994
SUBJECT: Condensate Drain Tube Eliminated
MODELS:
1994-1995 (AN) Dakota
1993-1995 (XJ) Cherokee
DISCUSSION:
The above vehicles no longer use an air conditioner condensate drain
tube. Cherokee's built after September 3, 1993 (MDH 09-03-xx) and
Dakota's built after June 1, 1994 (MDH 06-01-xx) no longer need the
condensate drain tube. Do not install in the field or submit a shortage
and error request.
Somewhere just below
the Suction and Liquid Lines you will see a small black hose coming
through the firewall and pointing down. This is the A/C drain hose. Take
a piece of wire and snake out the hose. This will clear the blockage
and allow the water to drain out.
You may have to remove the drain hose completely. If so, it just pulls right out and you can slip it back on easily enough.
