I have a C6 efan and controller, similar to ADM's setup, and I was wondering how often do your fans come on? Do they all ways come on with the a/c? What temperature do they come on at? Alvin at Pcm for less did the programming and sometimes they work good and sometimes they don't. Like if I'm at a light with the air on for a few minutes the air gets warm and the temp gauge goes past 210, or if I'm doing alot of stop and go driving it does the same. Yesterday in traffic I got a warning coolant hot and i look down and the gauge reads 260. I know the fan works because when it does come on i can here it and it keeps the temp gauge at the notch before 210. I know Alvin knows what he's doing, so I was thinking it's maybe a bad controller. What do you guys think?
