I recently bought a 1991 loyale, and the heater blower doesn't work. Thr knob turns but doesn't blow. How do I trouble shoot and/or locate the blower motor to replace?

The previously mentioned resistor pack only controls the slower speeds of the blower, no tht top speed.  If you have the control on "hi" and it doesn't work, the problem is elsewhere.


The ventilation blower lives in the right footwell, directly above your passenger's right toes.  If you remove the dash trim-piece underneath the glovebox, you will have better acess.


The blower is held in place by 3 (10mm???-headed) bolts spaced equidistant around the motor housing.  There are also another 2 screws that hold the resistor pack in place, and these usually need to be removed... and are often rusted/gummed in place.  There are also a couple of connectors, which should be obvious.


Common issues with the blower itself is the squirrel cage actually having squirrels (though usually smaller rodents and their nests), the commutator area being caked in carbon dust from the brushes and copper from the commutator... or the commutator being abraded down to uselessness.


Don't forget to check fuses before digging in too far.  The blower is easy, but fuses are easier still.

Check to see if voltage is getting to the motor while on high speed. If you don't have voltage on either lead to the blower motor then either a fuse is bad or the blower relay is bad. If you do have voltage getting to that point then look to the resistor pack for the trouble which is mounted to air duct for cooling.
