The cooling fan relay is normally located in either the underhood fuse and relay center or mounted to the electric fan assembly behind the radiator. One solution proposed on a British forum is the installation of a high power resistor to bypass the fan's defective internal resistor. Replaced it and new one blew when fan started to run. AUTEX Manual HVAC Blower Motor Resistor … If your fan only runs at high speed when it is on it is probably the resistor that has failed. I got things working by jumping out the relays but I can not get 12 volts to the fans. So both my rad fans wouldn't run on low speed due to the resistors being knackered. Those relays are located on the bottom row of the relay tray in the left footwell, just above the fuse panel. Mods: 3.8L TB upgrade. You could connect the wire from the t-stat switch to the green wire on the radiator switch and the radiator switch will activate both high and low relays giving you a high only outcome. The "bypass mod" did not improve voltage to the pump for me. Shop online or call 888-844-3393. I'd like to fix it right, of course, but: Are you sure this is not the blower itself? Join now!
