speaking of AC recharging
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

Re: Need help recharging the AC on a 97 Jeep Cherokee Sport
If you use a heat gun on the charging cylinder you can, I prefer doing it
that way to get the exact OEM recharge. Once the system is filled then I
run the compressor I have never had a problem and it takes no longer to fill
an auto ac system a 400 ton chiller is a different story. Also another
trick is leaving the system in a vacuum and draw in the refrigerant.

Re: Need help recharging the AC on a 97 Jeep Cherokee Sport
why not run the compressor and still weigh in the charge??????? Do that on
almost every system I charge...
