Could be a loose wire harness between speed sensor on the transfer case and the dash. Craig Bailey New England 2007 Chevy 2500HD crew 2015 Jayco Jayflight 32BHDS

Be careful.... I installed the factory option towing mirrors. The power glass (the flat) is held to the carrier with short screws into molded stand-offs. Long story short, those standoffs are plastic, but not ABS. So, when they break you won't be able to plastic weld them. The purpose of the standoff is so the telescopic mirror arms can fit behind the glass when retracted. Craig Bailey New England 2007 Chevy 2500HD crew 2015 Jayco Jayflight 32BHDS
