I have the helms, I've had this problem for about 3 weeks. the temperature sensor needle doesn't budge and i am not positive if the fan switch works. so i've ordered a new thermostat and the switch.
If anyone can help me after I install these and if I have the problem still, that'll be great.

 

It's very possiblt that your thermostat has gone bad, or your temperature sending switch is done for. Any of these should be a simple fix.

 

Could it be possibly a short circuit that cut the gauge cluster to go bad? Other needles are working except the temperature needle on the gauge cluster. Radiator seems to be working but the fan doesn't turn on even after driving.... I will keep an eye on it and update. thanks
