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!!!!
