the Duramax. Didn't think I was going anywhere today, so I didn't plug in the trucks. Winter cold has hit again. It 19° and feels like 1°F.

I forgot about the electric heat strips these trucks have! Running for a minute and vents are blowing 100°!

No, I don't think so. Maybe just how to use it.

Turn the temp knob up to high. That's it. Well, the computer has a play in it. Like outside temp, engine temp, etc.

But if it's cold enough to have the heater on and the engine isn't producing heat yet, they will come on.

Here is the "official" rules from the body builders manual! 😁

Now you know why the Duramax has 2 batteries besides cranking and what some of those high amp fuses are for! There are things that aren't known/taken into consideration when you make the decision to buy the HD's with the 6.6D. I like to call them fringe benefits! 😇

What else you wanting to know? 🤓

@pinebaron

I think the HD AEV edition comes with the trunk/bed monkey. I cannot find any info online nor in the OM. I have no personal knowledge, sorry, cause I bought the trucks before AEV was a thing and I didn't need a big lifted truck. 😉


You know what they say...if'n you have a big lifted truck, you're making up for having a small di~~!

ETA...C'mon you bastards, thats funny right there, it's just a joke! Don't get your panties in a wad and flood my direct message box!

I'll check out if my truck has it; front L/R temperature controls are digital and the few times I've driven or started in sub-zero temperatures I may not have noticed since I usually prestart and preheat the truck else be told off by you know who :)
 

So if I am reading this correct the 1500's do not have that option?? Dang, Love learning something every day.

With 26 degrees outside today, I was able to check mine; its not installed for sure.

I will see if I can track down the body builder manual for the refresh. Maybe that was another thing eliminated.

But I learned something. It's an option, look for C32 on you RPO codes sheet...

Nope mine does not have C32; I believe I'm limited to use of engine block heater to achieve the same result however it needs to be plugged in, whilst C32 would work anywhere :(
