2003 Buick LeSabre Problems

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.

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.

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.

I own a 2003 Buick LeSabre. This has been a great car except for the electric window regulators. I have replaced all 4 windows over time and now I am replacing one of them for the second time. I have been doing my own repairs after the first one. If I had them all repaired at the dealer it would have cost me over $2000 by this time. There are some real poor designs in these regulators. The mat...
