I have a set of 06 Escolade E-fans on my 2000 Seirra my pcm was tuned and I have a wireing harness but there is a problem... My fans are always on? It was 16 outside today and they were on as soon as I turned the truck on i hear them come on. Then when i put the a/c on or it comes up to temp they kick onto high, do any of you guys know what my problem could be? At frist i had a bad ground and they wouldent go on so i grounded it again and now there always on? im confused any help would be apperciated.
