Two problems related to engine exhaust system have been reported for the 1999 Buick Century. The most recently reported issues are listed below.
Battery went dead in car, 1999 in Buick Century on 11-10-03. Battery was replaced. Dual ac in vehicle then blew cold on passenger side but not the driver's side. Brought to shop. Computer was reset since vents were sticking but problem not resolved. Part replaced cost $646. 07. Problem noted in TSB bulletin # 02-01-39-001. Certainly should not cost the owner of the vehicle an additional $646. 00 each time the battery dies to have ac work properly. Since TSB bulletin listed the problem already, GMC Buick should be accountable for inferior workmanship. * cb.
