Where is the blower motor lcated on the vichele 1997 passport

most likely u r blower resistor melted common problem a new resistor can be purchased and a 6 inch lead of wire with connector that plugs in if more than two wires its resistor . a two pin plug means blower motor that connector can also be purchased with a new blower motor follow the melted wire to the cause u r on the right track danny ps it is all behind the glove box

Check the blower motor relay, usually located under the hood in a box, also check the fuse in the fuse panel for the blower motor. If both of those are good then you have a bad blower motor.

Remove or disconnect:
Negative battery cable.
Instrument panel (I/P) compartment.
Front screw from right door sill plate.
Right hinge pillar trim panel.
Electrical connectors from ECM, as necessary.
Electrical connectors from blower motor, as necessary.
Bolt from right lower I/P support.
Blower motor cover.
Blower motor cooling tube.
Blower motor flange screws.
Blower motor.

HEATING AND AIR CONDITIONING Blower Motor REMOVAL & INSTALLATION Fig. 1: Remove the sound insulator from underneath the passenger side of the instrument panel
Fig. 2: Remove the retaining bolts for the blower motor assembly
The blower motor and fan are serviced as an assembly only.

1. Disconnect the negative battery cable.
2. Remove the passenger side sound insulator.
3. Detach the electrical connections from the blower motor.
4. Remove the blower motor retaining screws, then remove blower motor and fan assembly. To install:
   
5. Install blower motor and fan assembly, then secure using the retaining screws.
6. If equipped, connect the blower motor cooling tube.
7. Attach the electrical connections to the blower motor.
8. Install the right side sound insulator.
9. Connect the negative battery cable.

check fuses first with test light,if it is ok,find blower motor and use test light on motor connector to see if you have power,if you do replace blower motor

Keep using it and see what happens. Might be ok. Does the motor sound different from before?

Start simple and check the fuse. If you can run the fan on certain speeds but not others, it is most likely the resistor. If the fuse is good but it wont run on any speeds, look at the relay (this component is first in the circuit. If all components turn out to be fine, look lastly to your blower speed control knob.

Could be the motor or the blower motor resistors. I would go with the resistors first.

check the fuses than check for power and ground at the blower motor plug with the engine running and the switch on high. if you have power and ground replace the blower motor. somtimes the blower motor resistor fails too but than the blower usually only works on high. I replaced 1 of each this week.

the problem could be either the motor is bad or the reostat (it controls the speed of the motor is faulty.) the reostat is located in the blower motor housing and has two wires going to it. the blower motor is located either on the passenger side fire wall inside the cab behind the glove box or on the fire wall under the hood. please rate this
