When I bought the vehicle it had no condensor and electric fan in it. Probably because the previous owner failed to replace it after some sort of damage. Anyway there was no gas in the system as it was open. Before the initial attempt at re-gassing I had fitted a new receiver /drier at a cost of $90. The final, successful job cost me $200 which I was pleased to pay as the cost could have been much more if there were issues somewhere else. The other thing that surprised me is that the panel on the top of the dash blows cool air now. I thought that I'd read on a forum sometime that the top panel was only designed to blow un-cooled air. Nevertheless a happy camper ready for summer. Thanks for the reminder to change the microfilter too. I have had it out previously and found it to be chocked up with leaves etc. At that time I blew the filter clean with my compressor but haven't replaced it as yet. Will do so now.
