GRID HEATER QUESTION
Is is normal for the grid heater to kick on and off wile warming the truck up? I just noticed my heater clicks on and off wile i let the truck warm up. I just got the truck a few weeks ago and never noticed this, but i also have been pluging it it until today and it's 9degrees out right now

not normal. once it starts they should shut off. Mine did the same thing and it was the computer. not saying thats your problem, but there is problem.

Well after searching I found this
"The grid heater is triggered by an air temp sensor in the intake manifold. It only comes on when the air temp is below a set point. In colder temps it comes on before starting, and will sometimes (really cold) continue to cycle for a short time after starting." So if this is true then I am ok due it being so cold out right now Wind chill is 8 degrees outside :humm: |
It is very normal for the grid-heaters to cycle on and off during the initial warm-up of our trucks.
Pending the intake air temperature, the PCM may cycle one, or both elements as needed. |
Thanks it stoped after a few times but just thought I would ask

Totally normal. Mine used to do it until the grid heater grew legs and went MIA.:w2:
