BEST ANSWER: This part is specific to 1997 to 2005 Buick Park Avenues. For your 2000 Buick LeSabre we do not have the appropriate part available.
Is there an installation video for this turn signal for my 2000 Buick Park Avenue?
Vern L on Jan 19, 2017
BEST ANSWER: Not specifically for a Park Avenue. I was planning on doing it my self but bought the control from 1A Auto for $99. My mechanic quoted $500+ just for the contol unit. He installed my 1A purchase for labor + 20%. Just under $200. My savings $400+. He also said it eas more difficult than other cars he has done. FYI
