I have a '98 TJ Sport with factory AC.
I picked up an R134a recharging kit the other night because my AC was blowing warm air on our beautiful 90 degree days!
I followed the directions to the letter but the system still didn't get cool. The compressor was kicking in as it should be(based on a butt-load of past postings I read about the subject here).
The tubing leading into the firewall just got a little cool, it didn't get cold. I'm afraid to add more refrigerant because I don't want to have too much pressure in the system. The refill package I bought doesn't have numeric pressure gauge, it just has the low/good/toomuch colors..
I'm no professional mechanic, so are there some basic troubleshooting things I could try here?
Thanks,
Tim
