1999 GMC Yukon Denali Question: Reverse lights stay on while driving
Answer #1patrick mannion from Greg Solow's Engine Room, July 18, 2010, 18:51Master
If it is a manual transmission there is a switch on the gear box that may have failed (pink and a light green wire going to it), if auto trans the reverse light switch is part of the transmission range switch. The pink and light green wire should have no continuity in any position except when in reverse if the switch is good.
