the blower on my A/C quit one afternoon. it worked fine that morning, then that afternoon, nothing. took about 3 hours of searching and internet surfing to find the problem. the good thing is that people aren't afraid to post what they find wrong and how to fix it. So my friend found a site similar to this one that had problems listed and fixes listed. That's what gave us a clue where to look. Luckily my friend had all the right stuff to fix the problem and it didn't cost me a thing. Thank you God!
