AC does not work, can't recharge

I have a '94 Explorer and the A/C stopped working. I checked the pressure on
the low side service port and there was nothing. I used a recharge kit with
uv dye to spot a leak and could not find anything. I used the goggles that
make the uv stand out and even used a higher wattage blacklight to spot
anything. No apparent leaks. I even looked in the condensor housing and
couldn't see anything. Any ideas?

What do you mean "can't recharge"? Were you able to refill the system?
Does the compressor clutch engage? More info needed.

I was able to refill it, it didn't hold pressure though, sorry, I thought I
was clear. As far as "can't recharge", I meant I put in refrigerant and there
was still no pressure after it. I don't know about the clutch engaging, I'm
just going by a haynes manual, and its short on details. Can you explain?
Could that be the reason why I can't find a leak, yet there is no pressure?

I thought it might be the compressor, but I thought the pressure would stay
the same instead of going all the way down after a recharge, but like I said,
I'm working from a haynes manual with very basic ac knowledge.

If I remember (vaguely) college thermo-goddamics,
compressing freon (increasing pressure) lowers its
temp, cooling the pipes it flows through, and then the
fans blowing you that cool air.

PS, I hated that course!

And, quite obviously, you didn't learn anything from it.... Compressing
freon is an endothermic process (increases heat)... passing the high
pressure gas through the condenser (funny name, isn't it?) condenses the
high pressure gas into a high pressure liquid. The liquid is delivered to
the evaporator through a restriction (most commonly, an orofice tube). As
the freon passes through te orofice tube, the pressure drop allows the
liquid to "boil" into a gaseous state. This boiling action takes place at
something well below freezing and removes latent heat from it's
surroundings...

For the original poster.. if you don't understand the system, leave it alone
and have someone versed in AC repair attend to it.... anything you might try
at this point in the game will only increase the eventual repair costs...

FerKrissakes.... if you guys don't know how it works... ASK!!!! Pretending
that you know what you are doing is like pretending you have a big dick...
someone, somewhere, somehow is going to embarass you...

Jim, you certainly have a way with words.

Jim, I'm not at all embaresed by my small penis, it gives me plenty o'
satisfaction. But I am having AC problems, not penis problems. Also, an
endothermic reaction is when there is energy put into a formula to create a
new formula. Heat usually is the energy, so there would be a decrease in
heat, thus a cold feeling. I don't like taking my vehicle in to the shop
because I always have to pay more than I have too. I mean come on, how many
hours does it take to put on a serpintine belt again? They were gonna charge
me for 4!!! Took me 15 minutes, i was just lazy and didn't want to do it, so
I figured I'd have the shop do it. Oh yeah, did I mention another shop wanted
to fix the ball joints that didn't need fixing and my tire was gonna come off.
That was 5 years ago. Tires still there and there still is nothing wrong with
them. So, if I can't get this friggin ac to work, I go without ac, so there
won't be any more costly repairs. So, how does one check to see if the
compressor clutch engages again?

first do your basics if you have a voltage reader test to see if the
comressor is recieveing any thing so it can turn on if that has been checked
then there is a I think its called a relay switch, Its usually wilbe by the
tank that holds the refridgerent and oil it will have 2 wires coming out.
