Coupla ideas: First, I suppose you could check continuity with an ohmmeter, there ought to be some small number of ohms. Second, if you have any means to measure upwards of 10amps of 120V current, you could plug it in and check current draw. I use a high-power Variac. Third and lastly, plug it in for a coupla hours and crawl underneath and start feeling around the block with a bare hand. In single digits and after 3-4 hours, I felt some warmth on the heads, mine was definately doing its job.
Hope these suggestions help. You do have the power cord, right? My '05 came with the heater, but no cord.

Try plugging in a high watt appliance, such as an electric heater or heat gun into the same outlet. If the block heater is working it will trip the circuit breaker. Don't ask me how I know this!

also your obviously going to notice the difference when you go to start up the truck.
I've never had the glowplug light stay on for more then 2-3 seconds when the trucks plugged in. It should take a good 8-10 seconds if the trucks not plugged in at 20-30 degree temps

I always find it somewhat amusing what the average guy can come up with to test an electrical device! Seriously, there has got to be one hundred different ways to do it. Such as using an extension cord made of zip cord which would be warm to the touch after some time of use. To each his own.
Honestly, I don't know how one can hear it click as there is nothing in there that clicks. Its a purely resistive device that is on all the time, no stat at all.
