The heater might blow cold air in a 2000 Silverado because the thermostat is sticking and not changing from cold to heat. The thermostat is usually located in a hose that leads from the radiator to the motor.

You may need to add water to your cooling system.

THE CAUSE for this is that when your cold air is on the petrol is used to create air. and that is how cars create cold air

I assume your car heater is blowing cold air, when the heater is on. It seems that, you have air on your coolant. that air pockets blocks the cooland to travel through your heater. it may be a sign of a bigger problem such as blown head gasket in the old cars, such acura legend

The most common reason the heater is blows cold air on a 1999 Ford Winstar is a bad thermostat or blocked heater core.

It doesn't really blow it out it just warms the cold air.

If you are saying the heater is blowing out cold air you need to change the heater core which is located inside the dash

One of the reasons a 2000 Jeep Cherokee heater would randomly blow cold air and then hot air and then cold might be that there is a problem with the hot/cold duct. The air or a vent might be inadvertently blowing periodically.

Low coolant and a clogged heater core are possibilities.

check the antifreeze level in the radiator, when a heater blows cool/cold air there is not enough antifreeze/water in the radiator.

You will hear air circulating in the cold air return (or return air grille) when the heater or air conditioner is running.

Maybe its broken. Or maybe you pressed the AIR CONDITIONING

It is because your heater is having to heat up so its blowing cold air out while its heating up.This means your heater is not very efficient and it needs to be checked.

One reason your home electric heater is blowing cold air is the heating elements are burned out. A bad thermostat may also be the problem.

A car heater taps off engine heat. If you aren't driving, then the engine is cold and there's no heat for the car heater to use.

It is probably your thermostat. That will make cold air come in. It's probably stuck open. The part is only about $4.00 at Auto zone.
