Review on Radio Control Steering Wheel Switch Buttons For Silverado, Sierra, Trailblazer, Envoy, Tahoe, And Yukon Models 2003-2009 - OE# 21997738, 21997739, 1999442, 1999443 Replacement by Alex Jain

Perfect replacement. They are a perfect fit and replacement. They can be tricky to install, but only because the wiring in the steering wheel is soo short. Make sure you look closely at the housing on the new set, it will help you figure out how to remove the old ones without breaking anything. Allow yourself plenty of time to wrangle the new ones in and have patience. If you are installing these, you've probably the type that cares about the small touches and details. I was frustrated installing them, but very pleased with the end results.
