Replace the Blower Resistor which is located behind the glove compartment. This is a common problem.
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.
You have to replace the thermostat it is stuck open. I would say. Do you have heat when you are driving? I Have the same problem and is trying to fine where it is located. It is usually at the top of the of the motor but not on my 2005 jeep.
The 2002 Jeep Grand Cherokee driver's seat heat fuse is located under the dashboard in the fuse panel. There is a secondary fuse panel located in the engine compartment as well.
Low coolant, failed thermostat, missing belt, failed water pump, failed HVAC control, etc
The cabin air filter filters the air used to heat or cool the inside of the cabin.
it is clogged
The blowers go out-It can be fixed and it's not too expensive. I have a 2000 grand prix that this happened to about 3 years ago.
how do you fix the heat in a 2002 Chevy impala
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?
Blowers should continue running for a brief period after gas is shut off to extract residual heat remaining in hot plenum from burn process. It increases the efficiency for a given amount of fuel use. The heat remaining in the plenum will go someplace. Better to blow it into your living environment that to waste it as exhaust.
Of course, it can. However, the more common problem is a broken blend door, particularly on the Limited edition. Check heatertreater.net for diagnostic information and an inexpensive fix.
