The low beam headlights went out while driving 50mph on a highway because a relay in the fuse box overheated and melted the fuse box. I know there is already a recall on the trailblazer from the same year because they are the same car but there is not one for the envoy.

The vehicles headlights keep going out at night will driving. I have been dealing with this problem for about 2 years, I am a certified mechanic and I believe the problem is the headlight relay that is overheating. This is the same gm part that is being recalled in other gm vehicles. Gm part # 15016745. So why has it not been recalled in 05 . The problem happens at random the light will go out while driving or parked it does not matter.

Low beam relay (headlamp driver module (hdm) burned out--same thing happened 4-9-2015. This time melted the fan relay and fused the two relays together. 2006 & 2007 envoys were recalled for the same identical problem. The hdm overheated and caused headlamp and daytime running lights to fail and not illuminate. Gmc plans to charge approximately $800 for entire new set up because box is not sold without all relays. Was told possible further expense if electrical problems are found.
