1993 New Yorker Fith Ave w/3.8. Cooling fans don't shut down even after turning car off. They just constantly run. Had to unplug them.
Car had worked fine, then I wanted to check tranny for specs to see what it was doing. I plugged my snap on MT 2500 into it. I had forgot to change the setting and it was for my 1990 Imperial w/3.3. I started the car up and went down the road to check my specs. When I turned the car off both the cooling fans kept running. I thought that was odd. I then checked my snap on MT 2500 and realized I had the wrong setting. So I corrected that. But he fans will not turn off even when the car is shut down and not running. So in order to keep from running down my battery I unplug both fans.
Today I checked the fan relay and it was fine. (I pulled it to keep the fans from continuously running)
Did I fry part of my computer where the cooling fans are controlled?
Or is something else going on? anyone know what else to check? I just find it odd that fans run even with car shut down?
Anyone else here use a MT 2500 scanner with transmission moldule? Any comments or help will be appreciated
