When the unit is turned on. I can hear the AC pump kick on and run. But the blower fan motor will not turn on at any fan speed. No setting on the AC will get the blower fan to turn on?

how about fan in on position?

The belt driven compressor may not be producing suction, does the fan motor change speeds when you move the selector settings?

sounds like blower bearings are dried out and will eventually lock up the blower..sometimes you can spray wd40 in the blower bearings and it will work fine for a while.. also check vacuum controls to the baffle dors in the ductwork..may have some leaks there.. should hear a slight hissing if really bad..repost findings

Sounds to me like the A/C clutch is no good and out of adjustment.You should goto your nerrest junkyard and get a used assembly take the clutch off then you learn how it comes off and install it on yours the save the pump for later use if needed. The clutch should only have a .010 air gap after install between th inner elctro magnet and the clutch plate it's self.

The resistors are in circuit only on the lower fan speed settings.
On the highest speed setting, power is switched directly to the fan motor.
Check fan power supply fuses,
Check power is available to the fan when high speed selected.
If all above OK, apply power directly to the motor to verify fan motor runs- if it doesn't the motor may need replacement/repair.

replace fan motor the fan doesnt change speeds unless done by u

Hi Phillip,

Check your thermostat wires to see if you have any of them which are bare and touching. If any are touching separate them and tape em up and try unit again. You have a direst short in your cooling portion of the unit.

there is a resistor block in the blower housing, it could have been damaged when the field mouse nested on the blower.

it is coils of wire ( nichrome wires) with 4 wires connected to a socket . this slows down the speed of the motor.

tnx 4 using fixya,

Well, the blower resistor handles the lower speeds and the hi-blower relay handles the hi speed only. if the fan still works on the lower speeds then the resistor is bad. if the fan doesn't work at all then your motor has failed and or burn't the relay out also. if you can get your blower to start by hitting the kick panel above the pass. side foot area then the motor is bad. if you are handy enough to drop the kick panel and access the motor then check the connections at the motor. Then wack the motor and see if it comes on then. you will most likely find the problem if you follow those simple rules above. Good luck.
