    It was the fan solenoid on the fire wall! Funny thing, my engine fan light was acting strange before the fan got stuck on. The fan would be on but the light in the dash panel that showed the fan was on quit coming on. Pulled the panel out and saw it was a circuit board for all the "check eng" engine lights so obviously no sticking a new bulb in or anything. But after I put the new solenoid on, not only did the fan function properly but the fan light in the dash panel did too.. weird huh? Well everything works now and thanks again you guys and this forum are the best!!

    You need to figure out why it won't shut off. Could be several different reasons.
