If there is 12 volts or more to the fan and there is sufficient ground then yes the Fan motor is bad. Sometimes you can tap in the area where the fan is and the fan might come on while you have the ignition and A/C on. The fan is located near the front passengers fett underneath. It is about 4 or 5 7mm or 9/32 screws remove them all and disconnect the electrical connection to the fan. When you buy a new motor you might have to change out the blade, very easy. Just pop out the center clip and you might have to tap the center spline with a ball peen hammer to seperate the motor from the blade.

1998 tahoe defrost not blowing air


Bad blower motor? Blown fuse? Check the wire going to the blower motor for the presence of 12 volts. Check the blower motors ground wire. If it's getting 12 volts and not working, it's time to change your blower motor. If not, check for a blown fuse.

2006 I-280. Why does A/C blow cold air only on high speed?


check fuse first
then scan PCM , oops you didnt and the BCM does run this stuff.
so not scanning it , you miss all those FACTS.

the blower is dead. (aka , not spinning , or silent)
on all cars made the answer is the same.
blown fuse, fuse marked BLower, is blown. LOL.
controls not turning it on, controls failure.
blower bad. (motor) hot wire it in place to test)
wires to any of the above.
or the resistor block bad, (if it works on high but not low)
i have the schmematic in hand.

the HVAC relay pulls in by command of the BCM
the relay then sends 12vdc power to the blower via fuse 41
the blower is now hot full time.
the blower then needs a ground to spin (run)
on high, the ground G601 via the speed knob,switch makes that ground connection, so if the fan dont spin and say the fan is ok
then the relay is not closing or the fuse 41 is blown. (why not look at the fuse first for all electric fails)
the BCM sees you, turn fan on, (heat or cold)
and closes this relay, on the left.
if the relay does not close, (and coil is ok inside)
the the BCM didnt see those HVAC requests.
use a scan tool and look for BCM errors..>??????

Blower motor for air conditioner stop working but when attached to separate power source blower motor works fine, also no fuses are blown.


Most likely either the controls are bad or the blower motor resistor. To check you can see if the controls are getting power and if they are sending power to the blower motor. This will tell you if the controls are bad or not.

Chk for power at the blower motor electrical connector. If no voltage, check the blower motor resistor, its within the blower motor vent (this controls power to the blower motor). Also, in theses vehicles water may have damaged the blower motor itself. Inspect the blower motor for proper function.

Air Conditioner blower no longer blows


verify that there is power to the blower motor and that a fuse is just not blown.
if the fuse is good and there is power to the motor you will need to replace the blower motor.

Quick tip that might help. Under the glove box is the blower fan, check the plugs that run to it make sure they have a good connection. then give the blower fan a little tap, mine was just stuck. could have been from dust or something. Or a plug might have been loose.
