Saturn L300 ProblemsA/C off for Engine Protection and Engine Reads Cold
The Saturn L300 may display the warning message "A/C off for Engine Protection" on the instrument panel. This may be accompanied by illumination of the check engine light and the temperature gauge reading cold at all times. This is a feature of the engine that is activated by the power control module when it detects the engine warming up too slowly. The OBD trouble code P0128 may also be stored.
The cause is simply a worn out thermostat that stays open at all times, preventing the engine from reaching the proper operating temperature.
Replacement of the thermostat will correct the issue.
Many electrical problems can be caused by a failing Body Control Module or BCM. Before replacing, the system should be properly diagnosed to verify there are no other issues, such as electrical shorts or other failing modules. Remedying the condition requires replacement and programming of the Body Control Module.
Illumination of the Check Engine Light can be caused by a loose or worn gas cap.

Mechanic not sure what it is. Really bad tires on front? What could that be? Happens only occassionally.
WHICH ONE HAS ALL NEW PARTS? STRAINER, FLOAT, SENSOR, HARNESS... I WANT THE BEST FOR THE CHEAPEST PRICE POSSIBLE. NOTE: THE SMELL OF GAS IS STRONGEST IN THE TRUNK AND IS GIVING ME A HEADACHE WHILE DRIVING. NO PERFORMANCE ISSUES. STARTS, RUNS AND IDLES FINE! THE PROBLEM STARTED ABOUT A MONTH...
