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?
