2014mp8 Posted November 16, 2021 Share Posted November 16, 2021 Having some issues with my day cab. Not sure if it’s all related or not, but: 2 outside roof clearance lights are not working. The 3 inner lights are working fine all my gauge cluster gauge illumination lights aren’t working EXCEPT the rpm/MPH gauge. everything else is working fine on the truck, has me a bit confused. side note, when I hit the clearance flash button on turn signal stick, I hear a relay click but nothing happens.

Glensts Posted November 17, 2021 Share Posted November 17, 2021 The rpm/mph gauge on ours stay on all the time regardless of light switch. So guessing light switch or relay is bad or breaker is tripping for that section of lights Quote Link to comment https://www.bigmacktrucks.com/topic/68749-2014-cxu613-lights/#findComment-483013 Share on other sites More sharing options...
