The 2003 Buick Rendezvous takes a 24" drivers side, 22" passenger side and a 16" rear wiper. See sources and related links below for more information. Since there are over 22 different wiper arm attachments, do not buy wipers just by length only. Be sure to lookup exact wiper blade part numbers by vehicle make, model and year for the brand wiper you decide to purchase. This ensures correct length AND correct attachment.
The front wiper is fuse #29 (25 amp) And the rear wiper fuse is #32 (20 amp)
Exact wiper lengths and attachments will vary based off of the year of the Buick Rendezvous. See sources and related links below to lookup by exact vehicle.
The 2003 Buick Rendezvous has the most common hook-end wiper arms on both front and rear. See the Sources and Related Links section below for installation videos. Also, purchase the replacement blades first and there will be additional instructions/illustrations on the replacement packages. Locate and press the tab or button where the wiper blade is inserted into the hook of the wiper arm and pull wiper blade out of hook. You may have to rotate and flex the blade to make enough clearance for the hook to pass through.
