smokin5s Posted May 8, 2007 Report Share Posted May 8, 2007 ok, so I bought a can of the charging fluid for my A/C. A few years back, when doing some modifications, somehow one of the A/C lines got accidentally cut so all of the fluid ran out of the system... since then, I've replaced the line. I tried charging it over the weekend, but as soon as I hook up the can, the meter shows that it's full... I tried pushing on the button to put some in, but it just shows red on the meter. I turned the A/C on MAX but that made no differnce. This is on a '97 Camaro. What am I doing wrong? Quote Link to comment Share on other sites More sharing options...
AJ Posted May 8, 2007 Report Share Posted May 8, 2007 sounds like a junk fill tube and gauge. if you want you can bring it by tonight with 3 cans of R134a and i can recharge it with my gauges and vacuum pump for $10. Quote Link to comment Share on other sites More sharing options...

dakotart Posted May 8, 2007 Report Share Posted May 8, 2007 is the vacuum pump to pull out all of the air in the system? sounds like a junk fill tube and gauge. if you want you can bring it by tonight with 3 cans of R134a and i can recharge it with my gauges and vacuum pump for $10.

craig71188 Posted May 8, 2007 Report Share Posted May 8, 2007 You pull vacuum on the system primarily to dry it. At lower pressure the moisture in the system "boils" at a much lower pressure. The dryer the system - the colder the a/c can get. If this system has been discharged for a while, you would benefit from replacing the accumulator or receiver dryer - the dessicant in the one on the car isprobably worthless.

hpfiend Posted May 9, 2007 Report Share Posted May 9, 2007 You need to bypass the a/c compressor relay... it is on the drivers side (if I remember correctly) in that black plastic box.. use a paperclip after removing the relay... Otherwise it will cycle and you wont be able to effectively fill it.. Quote Link to comment Share on other sites More sharing options...
AJ Posted May 9, 2007 Report Share Posted May 9, 2007 vacuuming the system out also allows for more A/C charge since there is nothing in it to fill the void (ie. air) You need to bypass the a/c compressor relay... it is on the drivers side (if I remember correctly) in that black plastic box.. use a paperclip after removing the relay... Otherwise it will cycle and you wont be able to effectively fill it.. red neck over fill method 101 Quote Link to comment Share on other sites More sharing options...

Vander Posted May 9, 2007 Report Share Posted May 9, 2007 Be careful, if any moisture mixes with the R134a, a chemical reaction will occur causing an acid to form. And that acid can wreak havoc on your A/C system. Quote Link to comment Share on other sites More sharing options...
smokin5s Posted May 9, 2007 Author Report Share Posted May 9, 2007 thanks, I appriciate it... since AJ is a GM Tech, I'm going to let him do it... the 10 dollars is well spent as far as I'm concerned if it saves my A/C unit and allows for my car to not be boiling hot in the summer time.
