AC is not cold, won't take R-134A
 

Hey all, looking for ideas for this issue. AC does not blow cold. I attempted to add some freon, and none would go into the system. Gauge never moved off 0 when I pulled the trigger. The fitting only fits the one side, so I know thats right. I have service scheduled for Saturday, becasue I can't wait on the wifes ride. I saw a vid, where it mentioned it might be the low pressure switch. Any help or advice would be appreciated.

You might have to manually jumper the a/c clutch to get it to start sucking in freon.

ok, so it may still need freon but if the compressor is not running....it won't pull in the freon? How do I jump the compressor?
