Defroster fuse

Hey folks,
I am in need of a new defroster breaker fuse. I have searched at all the local auto parts stores without any luck. I have found it on ebay, but 10.00 for a fuse is pretty ridiculous ( http://www.ebay.com/itm/New-OEM-Mini...00332188732%26 ). Considering it is a common fuse for almost any GM vehicle, you would think it would be stocked in stores. Part # is 12077843 mini circuit breaker 14.5 volt 30A. I could just use a regular 30A mini fuse but I would think that if GM would have wanted us to use a normal fuse, why not put it there in the first place. Am I not typing the correct words in the search field? HELP!

thanks
Chris

Chris,
The defroster uses a circuit breaker, I have seen a few guys replace the circuit breaker with (like you mentioned) a traditional style fuse, and not have run into any problems. After years of use the original breaker wears down, and eventually out, using a std fuse should be ok as long as you dont keep on hitting the power button over and over

Defroster fuse

I think the poster is referring to the rear defogger. It's probably on a breaker because of high-amp draw,along with seldom use. If left on,or if the beaker just trips. The next time you try using it, it will still work. I don't see anything wrong with using a fuse,unless it just blows them easily. Either way,you know what it is. I'd try it.

Thanks guys,
I was just hoping someone had a website hookup for these. After doing a search here I have seen posts on the subject but with no listing on where they got them. Standard mini fuses are cheap, I was just worried the original breakers had a much greater purpose. Thanks for the advice guys.
