1999 Chevy Silverado 4wd service light turns on then turns off, what causes that?
This morning as I was preparing to leave,
when I started my truck, my service 4wd
light came on. I restarted the truck and it
turned off. Just wondering if I should look
into repair, tested the and and it was
functioning fine, maybe caused by the cold
as it is -19°C (-2.2°F). Thoughts?
