I believe it's a green and black wire set. I just focused on the plug that goes into the blower motor. No need to slice and splice to change the wire orientation. Aug 3, 2023 · Figure 1 If your blower or fan motor runs at full speed regardless of the setting you have it on there is a very good chance your resistor is bad. The resistor is located below the blower motor in the cabin air box (red arrow). Please see our article on blower motor replacement for additional assistance on removing the motor. The heater blower motor stops working ? Testing the electrical circuit would be the proper way to diagnose . Looking at a wiring diagram an using a DMM - digital multi-meter , an doing amp draw test on the blower motor . The PRND321 an blower motor probably share a ground or power point . Looking at a wiring diagram for both circuit's would ...Dec 14, 2022 · To bypass the blower motor resistor, you can use a one-wire relay. Insert one end of the relay wire into the blower motor resistor point and to the other end too. You should only bypass a blower motor resistor in a short time or emergency only. However, it is not recommended to bypass a blower motor resistor, as doing so can cause damage to the ... In most cases it's the blower motor resistor. Below is a diagram of its location, the plug and how to remove it. Looking at the picture of the plug you will want to turn the fan switch to different settings (the ones that don't work as well) and if you are geting power to each of those conections at the plug but the blower motor isn't turning on, this will be your problem.There is a plug in jumper harness avaliable for installing a later model blower motor into an earlier 1992-2004 car, part #4W7Z-14A411-B (WT-56853). You could also cut off your old wiring pigtail and splice on a new one using kit 3U2Z-14S411-YBA (WPT-605) instead. | Cioinjyh (article) | Mwuqr.
