LEt me say first off i hate electrical crap.My new to me comp g just threw this code last night and I saw on my dic that the trans temp was 210 deg. The fans do don't come on when I turn on the a/c and when they finally do its on the low speed only. Is this a normal thing for these cars or should I throw a coolant temp sensor in it? Or do these thing have a separate fan switch? Im dont know crap about relays and ive switched relays all over and everything continues to work for the stuff I pull the relays from. Can I just run a ground wire or something to test the fans?
