an ignition-switched or
constant 12v. power
source and wire it to
the “+” terminal on the
control box.
Fan still does not turn
on
Fuse to battery
positive post blown.
Wires to terminals
“B” and “G” aren’t
properly hooked up.
Inspect the fuse in the

hooked to terminals
“B” & “G”.
Replace fuse.
Hook up wires for
terminals “B” & “G” to
battery and ground
respectively.

the positive trigger
wire from the A/C
compressor clutch.
Check if defrost
activates a/c or if the
a/c is on.
Splice into the positive
trigger wire to the A/C
clutch and connect
to the “C” terminal on
control box.
Shut off a/c or leave
