I have a 1990 Dakota SE, 4 cyl, 2.5L, 5 sp OD. The A/C gradually quit
cooling. It has been retro-fitted for R-134. I picked up a recharge kit
at Auto Zone and put in 3 cans of 134. It cooled that night and the next
morning but not since. The pressure reading was pretty low after
installing the 3 cans. Is it possible it wasn't enough refrigerant to
properly pressurize the system and cool accordingly? Or do I have a leak
that's too bad for the stop-leak in the refrigerant to seal up?

TIA,

Karl

Check all the connectors on the AC lines. They will come loose with just
regular use and if you do any off-roading it is even more common. Don't
overtighten them! Get them good and snug but don't go so far that you damage
the nylon and rubber seals.

If you do have a leaky connection there is a good possibility that some
contaminants have also gotten into the system. It may be a good time to go
to an AC shop and evacuate and then recharge the system. Contaminants can
and will eventually cause you many problems including possible compressor
failure and condensor problems.
