The Envoy/TrailBlazer/Bravada etc are all a part of the GMT360 platform and share identical parts. The rear wiper is really poor on the older models. If you order a replacement kit of the 2006 wiper from www.parts4chevys.com (listed under the TrailBlazer Upgrades) that will solve the wipe issue and be a great improvement in looks also! You can see the new style wiper installed on my '03 at the enthusiasts website ..... Blazernut ....in my Gallery! For more great info on these trucks join our enthusiasts forum at www.trailvoy.com
