I have a 90 cherokee and I have just converted the A/C over to R-134. I know that it isnt going to be as cold as R-12, but it should be a lot colder than it is. I have a couple of problems. First, the A/C doesnt blow very cold through the vents, but when checked, the system is at full charge. It does not have any leaks. I have not changed anything on the truck other than the freon. The system was never open for any length of time. My uncle was the previous owner and tells me that it had a very slow leak. I have not had any drop in pressure in the system now for 3 months. Is there something else I need to change to make the R-134 work correctly. Second, the air coming out of the vents takes along time to get going. It doesnt matter if it is High, Normal, or Bi-Level, it all takes a good 3-5 minutes to get going. It will blow out of the defroster vent immediately, but the rest take a while. When I use the heater, the air comes out immediately, no problems. I am knew to owning Jeeps and I am not yet familiar with the workings of the Chrysler way. I have been working with cars for at least 8 years now, but they have all been 65 - 72 chevelles. Any and all suggestions would be greatly appreciated. Thanks guys.
