Replace the module only if the new fan still fails to spin. Whats people lookup in this blog: Cooling Fan Resistor Test; Ford Focus Cooling Fan Resistor Test Next connect the jumper between M1 30 and V1, the drivers fan should run at low speed. The blowers in a 4th gen are a RARE think to find at a pull-a-part place. The switch on the back of the tstat housing activates the high side. Note to Vanagon Owners: This part is located behind driver side headlight.You must splice the connector plug from your old unit, as the Vanagon style plug is no longer made. There are some articles on VW forums discussing this design flaw. if its a junkyard van, ignore the bolt against the firewall, it doesn't destroy it, it just shears that last bolt joint. So both my rad fans wouldn't run on low speed due to the resistors being knackered. 6. Your order may be eligible for Ship to Home, and shipping is free on all online orders of $35.00+. You may notice that the cooling fans only operate at one speed, when they used to operate on two or more. Well, it might be ok then, but if I remove 10 bolts, I will later install 10 bolts, not matter what. Problems going on with my fans, I suspect maybe related to the 85/95 thermo sensors in the radiator. The leads were very small on the resistor I used so I soldered it to the wire. 19. 06-24-2020, 03:56 PM. $33.95. Cooling Fan Resistor Kit by Dorman®. One solution proposed on a British forum is the installation of a high power resistor to bypass the fan's defective internal resistor. All that circuit does is provide a low fan speed operation, Both hi and low speed use identical relays except one goes to the fan and the other goes to this circuit which is a honking resistor and a thermal cutout.
