block heater fuse?

[SykoStroker06]

Is there a fuse on the factory block heater? I had an issue with my GFCI in my garage that blew last weekend. Now,it seems that when my truck is plugged in it doesn't heat up. Is there a fuse that I blew in my truck? Is is possible that the block heater died on me? I tested the electrical circuit in the garage and that is fine. My truck goes in for service tomorrow and should I have them look for something?
Thanks,

there is no fuse for the heater. you might have a little bit of moisture in the cord. mine did that the other night. could have just possibly died on ya. leave it plugged in overnight and grab a radidator hose and see if its warm. know being in wisconsin i know it was cold teh other day and i had my truck plugged in for 2 days and it was still rough to start. 80mph wnds didn't help with the block heater on lol. should be under warranty. wouldn't hurt to ask to take a look at it. merry christmas

I left it plugged in all night. The air temp here was about 10 degrees and it was about 15-20 degrees in my garage. I grabbed the radiator hoses and they were warm. I will just have to leave it plugged in longer or set a timer for 3-5 hours instead of 2-3.
Thanks to all.

Those GFI recepticles are a PITA and high current will trip them. I took the GFIs out of my garage...got em in the kitchen and bathroom where they are a safety guard but i couldn't see a reason to have em in the garage.

It was required in our local building code. I had to put them in when I built my new garage so it would pass inspection. Thanks for all the input from everybody!
