I have a 2 1/2 year old system with the lighted switch that is discribed in operating instructions as "red line up and red box down." About 2 weeks ago the "red line up" went out. The system seems to be working fine on automatic, when the truck is up temperature the "red box" lights up and I'm running on hot oil. Everything seems fine....just... no red light.
Am I missing something or is it just a burnt out light?
