I checked for that when I got my truck. Didn't do it. Had all the updates and recalls looked after last month. Last night the temp was about 35 F and I turned the lights down as I was leaving the city. Yup... there went the blinking dash lights. They stopped blinking when I turned up the intensity, but everytime I turned them back down, then they blinked.. Drove the truck home parked it in the garage and shut it off. Started it this morning after it sitting in the heated garage all night and headed to work... in the dark. dimmed the dash lights and there was not any blinking. Don't know if it had anything to do with my NAV/Radio screen freezing up the day before and the reverse sensors not working either. Everything seems in working order today.
