Hi there:

In many instances, the failure to blow hot air into the cab of your vehicle is caused by a malfunctioning heater core. If the air pressure is low however it could be a fault with the blower motor as well or a sign of a faulty heater control valve. You might want to have a local mechanic complete a heater is not working inspection to help you diagnose what’s causing this issue so you can save time and money on repairs.
