If its an analog thermostat with a "Slider" for the temp, take the cover off and look in the lower right corner for a fuse. make sure its good.
Here is a wiring diagram

You might have to trace where the 12V line is coming from. One place is the control panel in the A/C unit. inside the return duct. I have seen White as ground and blue as heat.
