A standard multimeter and just ohm out the cord to check for no opens. If it's working you will see current draw

I recently moved back to Chevy after 14 years in Dodge diesels and I can tell you the Chevy block heater sucks. :cry:

The two Dodge diesels I had both had block heaters and when I plugged them in, they came on right now and the temp came up fast when I eventually started them in the morning.

I've tried the Chevy one, it's been below 0 most of the last week, -10 to -20F at night, and I can't even tell if it's working, even after being on all night, everything is ice cold in the morning.

I like the truck, they all have good points & bad points, but there are a few things to be desired and this is one of them.

It's supposed to work at 0 degree F or -18 C. (which is ridiculous anyway, it should work when you plug it in, period)

Going to be -25 F tonight and tomorrow, guess I'll find out for sure if it works.

I'll be having a dealer check it soon. (and potentially replace with a "on right now" aftermarket, any suggestions??)
