Tonight I was driving home, had the running lights on for about 10 miles, then switched all the way to headlights and hot air started coming through the vents. The air controls were on hot and dash vent but the switch was in the off position. It only lasted about 3-5 seconds but it was obvious. I tried switching between running and headlights a few times but could not get it to do it again. Has this happened to anyone else or am I losing my mind? Let me edit that last statement to "has this happened to anyone else" only!

 

Hmm this hasn't happened to me, but I do notice that when my headlights are on and my grid heater is cycling, the clock on the radio will flash to full power then dim again suddenly...there must be little goblins in the electrical systems

 

If you look....your headlights are dimming also....

 

Well I know the headlights are dimming because of the grid heaters...when I turn the headlights on, the clock dims for night driving like it's supposed to..but sometimes my clock decides it doesnt want to be dim anymore and goes back to bright for a split second and flashes...not a problem, just an annoyance
