I checked the fuse under the dash and fuses in the hood area and they are fine. If I dont leave my heat all the way on my temp gauge gets to hot. I noticed the fans arent working so I checked all fuses what could it be? A relay? If so where could I find that one and how do I check it. If not what else can I check?

You have a low speed and a high speed cooling fan relay. They are both located at the rear of engine compartment. Give me the 8th digit of your VIN and I can give you exact diagram of the relay location. Also inspect wire harness has not come loose from fan connection.
