2001 Buick LeSabre
Erratic Fuel Gauge Operation
It is common for the fuel level sensor in the fuel tank read the fuel level incorrectly. The sensor must be replaced to correct the condition. Our technicians recommend having the complete fuel pump module replaced on high mileage vehicles.
Engine Oil Leak From Intake Manifold Gasket
The intake manifold gasket can develop external engine oil leaks. The intake manifold will need to be removed and the gaskets replaced to correct this issue.
Engine Stalling Due to Mass Air Flow/Crankshift Position Sensor Failure
The mass air flow or crankshaft position sensor may fail causing the engine to stall intermittently. Proper diagnoses will be necessary to determine the cause of any stalling condition.
Poor Ride/Handling Due to Worn Suspension Struts
The front struts may show signs of wear, or be excessively bouncy ride at freeway speeds. This may begin to occur at around 75,000 miles.
Engine Overheating Due to Water Pump Leak
The water pump may develop a coolant leak resulting in an engine overheating condition.
The Fuel Pump May Fail Causing the Engine to Stall or Crank Over But Not Start
The fuel pump can fail causing the engine to stall and not restart. Our technicians highly recommend to replace your fuel filter every 30,000 miles to help prevent undue strain on the fuel pump.
Check Engine Light Due to Gas Cap Issue
Illumination of the Check Engine Light can be caused by a loose or worn gas cap.
Improper HVAC Temperature and/or Air Delivery Due to Failed Mode Door Actuator
One or more heater & AC (HVAC) air delivery and/or temperature mode door actuator may fail. This can result in incorrect air delivery or temperature. If this occurs, fault code(s) stored in the HVAC control module should be available to assist with diagnoses.
Erratic Shifting of the Automatic Transmission
The transmission pressure control solenoid may fail causing erratic shifting. Our technicians tell us that partial dis-assembly of the transmission is necessary to replace a failed pressure control solenoid.
Transmission Fluid Leak From Cooler Line
The rubber section of an automatic transmission cooler line may develop a fluid leak . In some cases the leaking section of hose can be replaced. In others, the complete cooler line must be replaced to correct this concern.
Check Engine Light Due to Gas Cap Issue
Illumination of the Check Engine Light may be the result of a loose or worn gas cap.
Engine Won't Turn Over Due to Coolant Leak From Upper Intake Manifold
The upper intake manifold may develop an internal coolant leak causing one or more cylinders to fill with coolant. This can cause the engine to "hydro-lock" and not turn over. Removing the spark plugs will allow the engine to turn over pushing the coolant out of the spark plug holes. Replacing the upper intake plenum and gasket is commonly required to correct this condition.
The engine can be very difficult to start after this problem has been repaired, it can be helpful to clear as much of the coolant from the intake manifold and cylinders as possible before reassembling the intake manifold.
Check Engine Light Due to Ignition Related Failures
Failure of the crankshaft position sensor, ignition control module, or PCM may cause the Check Engine Light to illuminate.
Engine Vacuum Leak From EGR Tube
The EGR tube may develop an engine vacuum leak causing the engine to run lean. The Check Engine Light may or may not illuminate.
Multiple Back Lighting Bulbs May Burn Out
I is not uncommon for various back lighting bulbs to fail, sometimes one right after the other. Most commonly the related switch our component is replaced. However with a little time and effort the bulbs can be replaced individually.
Door would not automatically unlock from the remote or when the master lock switch was opened and the window would not work.
Left Rear Door Module (Part #: 25654368) was bad -- Symptom: door would not automatically unlock and the window would not work.
troubleshooting: pried off the plastic cover behind the door handle (start at the hinge side), removed single screw and then starting at the bottom pulled off the door covering (It is held in with plastic snaps), found 12v going into the door module and deduced the module was the problem; found one on ebay motors ...
