2005 chevy tahoe no air blowing out of front vents for air conditioning or heat. back vents work fine.
As long as all the fuses are good.. its probably the blower resistor/module... located next to the blower motor under the pass. side of the dash..
Hi - I just came across your reply the blower resistor - is there any easy way to determine if the problem is the resistor or the blower motor itself?
yes you can apply 12 volts dc power to the male pins on the blower motor after removing the connector and observing polarity of the wires so you know which pin is the ground (negative which is the black wire, positive the red) and which one is the positive. you can use some small alligator clips and apply power and ground to the male pins on the blower motor (you can use a 12vdc battery or get power from the side of the instrument panel junction under the side plastic panel) If the blower motor is fine it will operate at full speed when power is applied. You can also check for power (test light or multimeter) at the female pins that plug into the blower motor to see if power is making it through the resistor module. If you have power at that connector and the blower motor will not turn on after jumping power to the two terminals, than you know the blower is at fault.

Take cover. Off of motor under pass side dash and you'll see a square device with wires coming out of it plugged in to the blower motor. Visually inspect the resistors on the device and see if there intact. Mine rusted the resistor legs and there was no connection. You could use a test light to make sure your getting power at each resistor. Each resistor controls a different speed on the dial. Hope this helps

fan motor, possiable blower motor resistor
is the fan motor different from the blower motor?
