You may have an issue, since you are not saying why you want to adjust temperature. I am presuming you want to go higher? If so, you may have a broken dip tube and that is now cooling your hot water flow.
See Pic Below, it will also show you where your thermostats are. Just remove the little cover & turn to the greater or lower temperature.
