can we just stay on topic, all i want to do is check my cord or my heater its self to see which is bad. and i dont have a fancy plug with a element on it. just a simple 3 prong male plug
ON the first page, 2003Silverado gave you the answer.
Plug it in and look for a spark as you do so.
Are you not getting a spark? If you are, it's working.
But if no spark , doesn't mean it isn't working!!!!!
for the 2003 that works. For later models, not a good indications. Somewhere between 204.5 and 2015 GM added a thermostat in the block heater circuit so it won't turn on above a certain temp, somewhere around freezing. So the plug in and check for a spark above that temps is going to head you in the wrong direction!!!!
From what i can tell my 2013 may not have a t stat built in. mine has just the normal 3 prong plug, from pictures i see the stat is built into the plug correct?
I'd check your diesel suppliment owners manual. It should have the straight scoop on the thermostat and if it has one or not.
