The "quickly ending" A/C fuse

[T4RunnerSteve]

Fellow 3rd Geners -- my son & I are having a problem with his 2000 T4R & the A/C -- here is what we're experiencing:

- A/C worked great last year. I'd replaced the whole system only 2 years ago -- compressor, condenser, drier, etc. w/ OEM parts

- the A/C button broke so after "paperclipping" it for about a year, I got a used OEM one off eBay. Oddly this new one would never turn off but at least the A/C was nice & cold

- this year, if we turn on the A/C, the button lights up & after a little bit of ice cold air, the 10A fuse under the hood blows. Change the fuse... A/C works again... blows

- my thought is a defective button. I get a brand new OEM A/C button this time & while it functions properly (turns on & off when you push it), the fuse still blows after a short time

We searched these forums & see everything from a bad A/C clutch to a bad alternator being suspects. Is there a way to test these two parts manually? Would be good to be sure what's wrong before buying parts. Also, any other ideas? It feels like the compressor *should* be fine since it's OEM Denso & so new...

Thanks in advance!

I didn't mean for you to have this topic deleted, just thought you would get more members seeing your issue if you also posted in the 3rd Gen section, I would leave this topic here, you may get some good suggestions from someone who doesn't visit the 3rd Gen section.
