I replaced the first fan in August. That replacement went out 3 days ago. It was under warranty so i got that one replaced free. The 3rd one stopped working today. Is it just bad luck or could the resistor be causing the issue? I thought if the resistor was bad, the fan wouldn't work at all, but it ran fine for 2 days and just stopped today after running for about 5 minutes. I hooked a battery up to the fan and it does not spin so i know it's dead, but could the wiring harness from the resistor to the fan cause it to blow? Any idea? Thanks in advance.
