Thought I would issue greetings and salutations from phx az. Recently aquired a 94 ls 400 for free. Thats the good news, bad news , I got it from my younger brother, if there are two of anything on the car its a good bet he broke at least one of em. This forum has been a great help in the last 2months , thought I would say thanks....so , thanks.
One quick question, the electric fans on the ac core always run whether the ac is on or not. Noticing that this model has a clutch fan , I am wondering if this is normal or is this a malfunction or some previous owners mod?
Thanks
Mike
