Lights On My Truck
so my truck is driving me insane and annoying the crap outta me lol. While ideling, driving and even after the truck is warm the headlights will dim then brighten back up and so do the interior lights. The truck has always done this but only when it was cold and the heater grid was cycling now its almost every time I drive and for the whole time im driving. Does anyone have any ideas????

yer grids are kicking on causing a high amprage draw
I always wanted to put a pressure switch in so when it saw oil pressure it opened the loop on the grids............once the motor sees oil pressure wala no more grids |
why would they be kicking on though after I have allready been driving for over a hour and the truck is warm?
|
thats a good question..............and it dont even get cold in Texas either
I honestly dont know where it gets its temp reading from but oyu have some kinna problem there |
is it the sensor that in the intake tube just after the filter?
|
yea I drove a pretty good distance last night and the truck never did it from the time I left the house and all the way there and never shut the truck off but the whole freakin way back I had to look at my headlights going dim and then bright again. I really felt like getting out and shooting them lol

I found this pic and circled yer inlet temp sensor....................I still dont know if this is where the grids gets its reading from.........but I would bet it is
|
Does the IAT sensor come into play here? What makes the grid heater cut in/out? ECM?
|
Hmm you just beat me to it Whitmore....
