Hi

Can anyone tell me what the plug (power connector) to the blowers voltage is suppose to be, It has 2 wires one light colored and a dark one it looks like the dark one has power all the time even with the car off? the other doesn't seem to be a ground. the blower just stopped working turned car off to get fuel and then nothing. AC work it get cool when driving with the fresh air control on and the compressor engages. if anyone has the wire diagram that would be helpful too

Thanks in advance
