Does my blockheater work?

I have only tried plugging it in twice but both times I didnt hear or see anything when I plugged it in or the morning after when I woke up. Is there any way to tell if it is working?

You could try using a IR gun that you'd point at it.
Or an ohm meter to test to see if you have continuity throughout the circut, of course do this when it's unplugged.
Or the way I was taught>>plug it in wait 10 minutes then crawl under there to see if it's warm. Caution it maybe more than warm don't burn your hand.

^^^ just slide under there and feel for warmth.

DVOM (multimeter) on ohms scale across the two flat plug-in terminals....you're looking for 12-14 ohms.

Ok so I left my block heater plugged in all day today and just went and started the truck and I am going to assume that it isnt working because there was nothing different upon startup. How do I go about fixing this?

What are your symptoms?

What have you checked?

Let me make sure I am reading this correct. You plugged your truck in and it was like that all day. You then started your truck but noticed nothing different when your truck started. The point of having a block heater is for cold weather. If your truck is starting just fine without it being plugged in, your glow plug circuit is working properly. You wont hear it working, its basically like the heating element in your hot water heater.
