2006 Envoy Denali V8

This is a hard to find part. It is a unique fuse box layout for the subject vehicle. It is much cheaper here than from dealer if they have it. My mechanic ordered the wrong one the first time and there is no return as is the case here. But. You can't go wrong if you follow the provided online identifying procedure which removes the risk of ordering wrong one. Came with many fuses and relays. I did have to obtain some from old panel as vehicle is highly optioned. Panel is slightly different than old one with some of the relays alignment and an extra fuse not shown on my diagram, Initial problem was intermittent start and dying while driving as well as intermittent low beam headlights. This fixed it all!!! Shipping was fast for part. I had some trouble getting harnesses unplugged but finally got it.
