I CANNOT GET MY REVERSE LIGHTS TO WORK IN MY 2004 GMC ENVOY SLE. I HAVE REPLACED THE BULBS AND CHECKED THE FUSE #27. IS THERE ANYTHING ELSE I CAN CHECK? I NEED AN INSPECTION SOON! PLEASE HELP!
There is a Park/Neutral Position & Back-Up Lamp Switch that may have gone out. It is like a $50 to $65 part, you may want someone to check this out.
Also it may be just a matter of a bad connection at a plugin, or to clean up a ground wire.
