Hey guys i just bought a new a/c blower sinc ei dont have a/c this blower is all i have for heat. Anyways a mechanic whom I cant contact left hanging 2 wires by the console two black wires one gives a spark when i ground it to a bolt and teh other just chills.... they seem to be thick wires. Anyways Im thinking this wires power up the blower since im getting no air at all. CAn anyone help? is for a 88 rx-7

 

First off, don't scrape wires against ground to check for power. Good way to blow fuses...

On my S4 schematic, the wires going to the blower motor are blue, yellow, red/yellow, blue/orange, blue/yellow, and green/red. And one black, which is the ground...

The wires that have juice on them are the blue and yellow. So maybe it was the blue that you got sparks ffrom?

 

nah... it was definatly black. ill chekc it tomorrow and see whats up, thanx wayne u always help me

 

Find the plug on the blower assembly, and if it has a blue wire coming out of it and staying with the harness, then we'll know that it wasn't the one you found power on
