I have a 2001 buick lesabre and the dome lights and door locks quit working


check the positive wire coming off the battery, It should split into two branches, one goes to the starter and the other runs nearly everything else. Mine was corroded and I fixed it with a kit from Autozone.

2001 buick lesabre, shifter wont move out of park, the car runs, brakes good but wont shift.


Check the BTIS(Brake Transmission Interlock Solenoid). This solenoid allows the shifter to be moved out of Park only when the brake is pressed.I did not like this idea(the first year it was introduced,we had to replace that solenoid on every Buick Skylark).We had so many on the lot that I decided to just carry the keys and my tools around the storage lot instead of binging them into the shop to save time.

Computer problem


I would check on Ebay or a local salvage yard for cost of the computer.
I had a computer changed in a 1990 Cadillac Deville that cost only $80 for the part and $200 for the diagnosis and replacement labor. Probably a 2001 Buick LeSabre would cost more, though, unfortunately.
