I talked to another guy and he said it probably was due to the mud caked on the backside of the radiator and then to also change the coolant casue we dumped a ton o water for a last ditch effort once the coolant tank was empty.....
Also i was going to take the thermostat out and see if its opening and closing.

The problem with any of this is you said it went down with the A/C turned on. If that is the case there is something wrong as the A/C only puts the fan on high which it should have already been on. If the temp gauge moved, the computer knew you were getting hot and should have put the fan on high speed. With the A/C on the engine bay temp will rise as the condenser dumps hot air into it. (page 337 of the owner manual) turning on the heat will draw heat out of the engine bay, but not all that much, but maybe just enough to stop a boil over.

what i meant to say was that once i stopped i hit the ac and then the heat to see if the temp would go down and it did so it may be due to the fact that i stopped or the fact that i turned the heat on ......idk yet but i have a few things im going to try over the weekend.
this is the cause from some heavy mudding and the mud was heavy and sandy so it fubarred my fan motor. My radiator is caked full.
