New blower motor blows fuses

I checked, nothing. Its weird, it will work fine with the key in on, no engine running, but after like 5 min with the engine on it blows. Someone told me that its probably the ECU, which I hope isn't the case.

I would doubt that, our OBD1 ECUs don't mess with fan contorls at all.

Well this has been a huge pain in my ass. So my old blower motor took a nose dive and blow out like 3 months ago. There was red crap inside it and all over my seat. I replaced with OEM part and replaced resistor. The damn 15a fuses keep blowing out, so I put in 20a per my engineer at works advice. Now I have a nice burning odor, which I assume is over-amping of the motor. Could it be possible Autozone gave me a bunk resistor? Any thoughts would be appreciated.

 

 

I would think the resistor is incorrect.

That's a negative, unless autozone sold me the wrong resistor which matches up perfectly with my connectors.
