On a long trip last week, when I reached 70-75 MPH a light that looks like a wire coil would light and a buzzer buzz 10 times, then go out, then repeat. No codes in the memory??? Any ideas?

I think about the times it is either hard to plug in or you can't. If you are home you could plug it in. But on the road it may be hard to find a plug at times. If you get back up in the woods there are no plugs so it would either be a generator or that diesel heater.

I don't need it down here. But I could use something to keep the inside of the truck cool. I have been burned from a seat before. If I could set a timer to turn the a/c on ...

 

way to revive a 5 year old thread lol...

sounds like maybe your ignition switch is acting up?

what year of truck are we talkin about anyway?

 

I am going to replace the intake air temp sensor and the air intake charge sensor first. If this doesn't do it, it sounds like the computer flash update I had recently could be causing the problem.
