Tried to get my dealer here in Eureka,Ca. recently to complete the TSB for quicker winter time warmups at idle(flashing computer). I approached it like a warranty complaint that it was impossible to preheat the truck by letting it idle in freezing weather. They asked me if I was using the block heater. I told them no since I was staying mostly at hotels when I was encountering the freezing temps. They told me there was no such TSB except for the one about using #1 fuel. All they did was drive around the block and said it was heating up fine. Has anyone living in warmer climes been able to get their local dealer to do this TSB,or are these guys just lazy because it doesn't get that cold around here?
