You get your heat from the hot coolant from the engine (on a normal ICE vehicle) going through the heater core, when the coolant level is low from a leak, it can/will affect the function of the heater in the vehicle… Now there are many reasons a heater may not work, but since you also say you have a leak, then the 1st thing you need to do is find and repair the coolant leak and properly bleed all the air from the coolant, then there is a good chance the heat will once work again, if not then you will need to do a heater diagnostic… So, most likely you have one issue making it seem like 2, but you could also have 2 separate issues to take care of both.
