There are 2 relays.
1 for high speed and 1 for low speed
They are mounted on the inner fender drivers side.
I think that are 4 or 5 relays in a row.
The 2 fan relays are NOT side by side.
I do not know what the other relays do.
The reason that there are relays is because the fan draws about 20 amps.
The blower motor is the fan for your heat/defrost/ac.
There are 4 wires on the fan, like I posted before. The 2 green wires are the +12 volt.
Light green and dark green
Black is ground
Yellow is unknown, might be a feedback for the computer.
