hey guys...im not sure if the AC is broken but i hear the fans turn on and the compressor as well...i think it's low on frion....however, how do i fill that up and where can i get some? how much do i put in? any usefull links?

 

I need to know which of the Schrader valves on the A/C lines by the ABS are the low and high ( suction & discharge).

TIA,
Jeff

 

I'd just take it to a shop and have them add it.

 

These are still r-12 right? That could be expensive!
