Joey Mack Posted October 27, 2022 Share Posted October 27, 2022 If someone tied into the back up lights to install the beeper, check there, and the ground.... jojo Quote Link to comment https://www.bigmacktrucks.com/topic/70626-no-reverse-light-and-alarm/#findComment-513689 Share on other sites More sharing options...

Mackpro Posted November 4, 2022 Share Posted November 4, 2022 Being it’s a GR , all the lights go through the LCM . Light control module. In the fuse box on top of the dash check all the fuses marked LCM1 -2-3-4-5 . There possibility as many as 6. Also there is a fuse F49 that is related to the back up lights .
