If the fan wont turn on, you probably have a blown blower motor resistor. If it blows but wont blow warm, check your coolant level. If low, look around the engine compartment for a chalk-like residue (residual coolant splatter) and try to find the source and fix that

Heater does not work. Truck dies at stops

As far as heat goes I would replace your Thermostat and that should stop it from blowing cold due to the fact its probably stuck open unless your heater switcher arnt switching from vent to heat when you turn them. Does your temp gauge show your truck is running cooler then it use too? As far as it dying when you come to a stop that might be a few things I would check idle screw first then plugs clean or replace then Go to throttle position sensor (TPS) or AIR TEMPERATURE SENSORS (IAT) sensor. They somtimes wont turn your service engine light on but still will cause problems if they need cleaned.
