How do I make my account compressor on so I can refill with R134 it's a 00 XJ

 

you can check pressure with the can gauge, probably low. add some and see if it kicks on/off.
add a little more and check pressure. if it in the ok zone it should work, for a while. if it leaks down overnite, you need work. mine worked for 3-4 months.
then rebuild.

Amazon has some good deals on R134, especially if you buy multiple cans. A six-pack goes for $36.49, a dozen for $50.95.

 

wally is 5 bucks for one!! 6 pack $30 no shipping!!

 

Sounds like their price has come down. Last time I checked Wal-Mart in this area I think it was more like $8-$10/can, though I haven't looked there for a while. (I have a friend in the business and buy the stuff wholesale a case at a time.)
