So I had problems with the blower not working so I replaced the blower transistor. This worked for about 15 minutes and the blower turned off. Now what's the problem? Obviously there's a bigger problem than the transistor but did I blow the transistor I just bought? I bought it from partsgeek.com and made sure it was compatible with my car and it even looked the same as the old one. What's the deal?

 

Not sure if it means anything. But when I unplugged the one I just bought it was really warm.
