About a month ago I had some issues with a rad fan I was using with my aftermarket radiator. Long story short I had wired it up wrong. While troubleshooting, I had the heater on full blast to help keep the coolant temps down while driving. During trouble shooting, The I heard the blower motor go off while the key was in the on position(I had hard wired the wrong wire to the relay). I checked and replaced the fuses and heater relay but I still haven't been able to get it to work. I also tried a known working rectifier which was a no go and hard wired the blower motor to the battery and confirmed it was working. At this point I'm not exactly sure what to do. Anyone have this issue before?

 

"I also tried a known working rectifier which was a no go."

Rectifier for the alternator? This blower is not working whether engine is on or not, correct?
