Thermostat?

I have a 93 DAK CC 2WD 6cyl 3.9L 5 speed
I have no heat in the truck, the defroster blows cold
My temp gauge has lately been in the hot zone
A few weeks back I thought it was acting funny, typical cold and start
to increase as the truck warmed up, then the thermostat opened and that was
it
I think it stayed opened from then on
This is the original thermostat (~ 185K miles)
Should I replace it or do I have a bigger problem?
Thanks, Kev
