Air Conditioning problem
1998 Chevy Silverado V8 Four Wheel Drive Automatic

If I replace the high pressure switch will I loose all my freon and should I vacuum the system when performing this?

Hi
Switch is on a schrader valve so no loss of freon. Be sure to lube O ring.
Hope this helps
Thanks for donate
