Five problems related to wiring have been reported for the 1999 Buick Lesabre. The most recently reported issues are listed below.
In Dec 2010 I turned on my rear window defroster on my 1999 Buick Lesabre. It did not work. After checking repair options in the auto manuals and on line, I still could not get it working. When my son came in for the holidays, we decided to check the wires at the rear window. We discovered a square unit attached to the body under the roof panel. This unit had an entry plug which was burned and an outlet plug leading to the grids on the rear window. It also had the radio antenna leading into it. The unit and the entry plug were burned. My wife and I both smelled something like a electrical at one time but did not know where it came from. What I am asking is that: could this unit cause a fire or be subject to a recall? I know it is in other gm cars as well as our Buick. The part in question is gm 25623688. I have since replaced my unit and repaired the wiring. Thank you for your consideration!.
The event leading to the incident involved turning on the rear defroster. After turning on the rear defroster I smelt smoke and burnt electronics. The rear window would not defrost. I turned the car off and pulled off the panel near the wire running to the rear windshield and discovered the "power radio amplifier" had melted and caught fire, resulting in burns to the panel and complete loss of radio and rear defroster. This of course made it impossible to defrost the rear windshield. A replacement part was bought and installed by myself (the wiring harnesses and cables needed to be repaired due to severe burning as well). I still own the old burnt part.
