Auto a/c …. I’ve countlessly searched through the forum trying to figure out why my clutch isn’t engaging. Old A/C compressor was changed because of a bad clutch but it still blew cold air when it would work. I changed it along with the drier and had the system vacuumed and refilled at a shop, no leaks. I Bypass the relay and it clicks, blows ice cold. No red dot on screen still shows frost symbol. I know there have been many people who’ve had a similar problem with this so I’m hoping anyone whose experienced this can help me get on the right track to figure out was causing it to not engage.
