Radiator Fan Not Working

I own a '99 gtp and I realized about a month ago when it started to warm up that my radiator fan was no longer working, and looking back I think it has been broken for a few years now. So I decided to replace the entire assembly...no luck. I then replaced the three relays involved with the fan as well, also no luck. Fuses were all fine too. I went back and made sure the connectors were properly in place as well and they were fine. Any ideas?
 


The radiator fans don't kick on until the coolant reaches some ridiculous temp around 220 or so.

I think unplugging the coolant temp sensor turns them on. Try that. If that works, then congratulations your car isn't over heating.

yup, fans wont come on till 212, 220 something is high speed.

if turning the a/c on does not turn the fans on instantly, unplug the temp sensor if the fans just run full time now your temp sensor is bad.
 
I know they don't kick on until 215 or so but since I've replaced it it has almost overheated a couple times, with or without the A/C on. I'll try removing the sensor and see if it turns on.
 


dont remove it, just unplug it, it underneath the t stat housing on the lim.


if you take it out coolant will leak out.
