MY 86 gt has dual contour fans. Since I am on a budget I don't have the temp controller. I just have a switch inside the car I flip on when it is warming up. I heard these fans are 2 speed(high/low). Is this true? Does anyone have a wiring diagram for these fans?
Your best bet is prolly to get a manual for the car these fans came from and look in the wirring digram.Also to check if there 2 speed you should see another wire that would take the "+ volts".Then that would either be you high or low speed.How many wires are comine of your fan?
