Default 1996 LS400 Ac fan won't cut off when AC is off..HELP!!!!

I recently changed my Ac condenser fan because it stopped running, after doing so the fan now stays on all the time evevn when the AC is cut off. ANY SUGGESTIONS?? FYI I have checked all the fuses & Relays.

Make sure that the coolant temp sensor on the bottom of the radiator is plugged in? If it is unplugged. IIRC, the fan will run continuously.

Also make sure the radiator fins are cleaned out. Dust, leaves, etc builds up causing it not to ventilate properly with the end result of the A/C fan staying on all the time. If that's the case for you all you need to do is get a garden hose and spray from the inside out (meaning point the nozzle towards the front on the back side of the radiator and watch all the debris shoot out) I had this same problem with my '95 which solved the problem.
