stsjoe Posted May 19, 2004 Report Share Posted May 19, 2004 unhook the battery, or clear the code in diagnostics, hook up the can then start car and turn ac on compressor should run long enough to draw coolant. as long as the code is there the compressor wont come on(nice grammer ehh) Link to comment Share on other sites More sharing options...
Ranger Posted May 20, 2004 Report Share Posted May 20, 2004 Have the can hooked up valve open and ready to go when the car is started and the A/C is turned on or it will set a code and disable the compressor before you can get to it. Link to comment Share on other sites More sharing options...
