Best Answer

there is a blower motor resistor in these, read up on it everyone should have a manual for their vehicle, and the library should have a professional shop manual available in the REFERENCE section...make copies of the right sections...good luck :)

Where is the blower motor resistor on a Ford Windstar?

What the blower resistor doesThe resistor provide the blower fan with multiple speeds.A blown / failed resistor will result in the heater fan blowing on HIGH speed only.The Ford Windstar blower has a resistor block that controls the various speeds of the blower motor. It is located on the passenger compartment side of the blower housing and can be replaced in five minutes.AnswerIf it is in the same spot as the 98 windstar, then it is located under the dash of the passenger side. It is actually really easy to change. Two screws and the plug and it is removed. AnswerThe blower motor resistor pack has failed. Replace it. On my 2000 windstar rear fan although it has a multi speed selector is only wired up in the harness for single speed, the front fan does have multi speed.AnswerOn the evaporator case. AnswerOn a 98 Windstar it is underneath the front blower motor and has 4 wires on a plug. The glove box doesn't need to be removed or opened. It's held in by 2 8mm screws. You may very well have a blown fuse, check all the fuses for the air conditioning system, there is a box located on the driver side of the vehicle in the drivers foot well, a diagram with all the fuses and their amperage will be on the cover, remove the cover and locate the blower fuses for the A/c. If the fuses are not blown, then it may very well be that the blower motor is damaged or the control is not working properly. It is recommended that you take it to professional service shop if this is the case due to the many probabilities of a vaccum leak or a electrical problem that is best solved by the professionals.Its on the passengers side under the dash and its held in place by two screws which will located on the a/c evaporator housing...................

How do you change a blower motor resistor on a Pontiac grand prix 98?

The blower motor is a variable speed motor. The higher the voltage applied to the motor, the faster the speed. Depending on the HVAC (Heater Ventilation Air Conditioning) option installed in the vehicle, blower speed control could be through a set of resistors or through a solid-state blower motor control module. Battery voltage to the blower motor is supplied by the heater & A/C control by way of the blower resistor (or blower motor control module). At low and medium speeds, the voltage is stepped down by the blower motor resistors. At high speed, the blower motor relay is energized, removing the blower motor resistors from the circuit. Battery voltage is then applied directly to the blower motor through the relay. The motor will then run at maximum speed. Several types of HVAC systems were available on these vehicles, from manual to fully automatic electronic control. The blower motor speed can be adjusted manually by pushing the fan switch up or down or automatically by placing the heater & A/C control in the AUTO mode. In general, this system is reliable. Because so many of the control operations are electronic, special diagnostic equipment really should be used for system diagnostics and check-out. An authorized technician using a scan tool can most quickly locate HVAC problems.An inoperative blower motor could be caused by the following: Blown fuse(s). The fuse should be replaced. There may be both a LOW BLOWER and HIGH BLOWER fuse. Some models may also call it the HVAC fuse. Even the RADIO fuse is used in some applications. Check them all. If a fuse is blown there may be a short to ground in one of the power supply circuits. Open Circuit. Check the circuit between the ignition switch and the blower motor, and the blower motor ground circuit. Repair as necessary. Faulty blower switch. A faulty blower switch should be replaced. Most heater blower circuits also include a blower motor relay (look in the underdash convenience center), as well as a blow motor resistor. These items should be checked especially if the blower runs in one or two speeds, but not all speeds selected. REMOVAL & INSTALLATION Disconnect the negative battery cable. The blower motor is located on the passenger side of the vehicle, under the instrument panel. Remove the right side sound insulator (trim panel) by removing the retainers and disconnecting the courtesy lamp. Detach the blower motor electrical connector. Some applications may have cooling hose to the motor which should be disconnected.Unfasten the blower motor mounting screws, then remove the blower motor from the vehicle. If the blower motor fan (also called a 'squirrel cage') must be replaced, use the following procedure: NOTE Do not hammer on the motor to remove or install the fan. Do not apply force to the motor housing to seat the fan on the motor, or motor/shaft bearing damage could result. Do not apply pressure to the fan rim. Be sure the correct replacement part is used. Remove the metal star clip retaining the fan cage to the motor shaft. Remove the fan by pulling straight out. To install: If removed, install the blower motor fan, as follows: Install the replacement fan cage onto the motor shaft. Adjust the fan cage to get a clearance of 0.30 inch (7.5mm) to the motor mount plate. Install the remaining components in the reverse of the removal procedure. Make sure the electrical connection is secure. Tighten the motor screws to 14 ft. lbs. (20 Nm). Connect the negative battery cable, then test the blower motor for proper operations
