There are several reasons a 2002 Jeep Liberty could overheat. Some possible reasons are low in coolant, a bad thermostat, or the head gasket went bad.
If your 2002 Jeep Liberty has no heat, it could be due to several factors. Common causes include low coolant levels, a malfunctioning thermostat, a faulty heater core, or issues with the heating controls. Additionally, a clogged heater core or a failed water pump can also prevent hot air from circulating. It's advisable to check the coolant levels first and then inspect the heating system components for any faults.
If the heater in a 2002 Jeep Liberty is not getting hot, it could be due to low coolant levels, a malfunctioning thermostat, or a clogged heater core. Low coolant can prevent proper circulation, while a stuck thermostat may not allow coolant to flow through the heater core. Additionally, a clogged heater core can restrict airflow and prevent heat from reaching the cabin. It's advisable to check these components to identify the issue.

Centrifugal blowers are used anywhere a large volume of air flow is required. They are found virtually anywhere, especially to distribute heat from furnaces. They're virtually ubiquitous in industry, or used by almost everyone to some extent.
In some ac systems the blowers wont come on if only a slight tempture change is needed, or ther could be a problem in the wiring and the blowers are cut out of the heating loop It could also be that the fan limit is not working properly. Do the burners shut down after a few minutes of heating?
