There is more than likely a separate fuse and or relay that controls the right side trailer brake/turn signals and the left side trailer brake/turn signals. This fuse should be located in the power distribution center under the hood of the vehicle next to the engine but it could also be in the interior fuse box. If you can let me know the year on your Envoy I would be glad to let you know which fuse/relay to check. If not then you can find this information in your owner's manual or printed on the underside of the lid to the power distribution center. If the fuse is bad then you will be able to see this quite obviously but if it is a relay that is bad then it will make a clicking noise but there will more than likely be no visual cues.

If the fuse/relay is in working order then I would first check to make sure the bulb is still intact and then check the ground. Let me know if you need any further information and or advice.

The fuse(s) you will need to check in the power distribution center on your 2008 GMC Envoy for the driver side trailer lights is the #51 fuse. For future reference the #50 fuse is for the passenger side trailer lights. There are not any relays in the power distribution center for either the driver or passenger side tail lights.
