1991 Nissan Pickup (D21) Question: What is the low side
Answer #1pushrod July 27, 2013, 08:23Master
The opposite of "the high side!"
The fitting to add more freon to the A/C system. I assume you have ask where to charge the A/C system and was told that. Instead of me typing a bunch of words, try youtube and search for a video on how to charge an A/C system. Bet you will find one!
