It sounds like your blower motor may be bad. I don't know if you know how to check power at your blower motor plug, but you can use a volt/ohm meter or a test light. If you have power (12VDC) , your motor is most likely bad. There is also a resistor block module which has 2 resistors on it. It controls the motor speed basically by restricting the power by directing it thru one of the resistors. The higher the resistance, the slower the motor turns, thus the 3 speeds for the motor. The resistor module is mounted on the blower housing and has 2 screws holding it in with a small plug connected. It is just about straight ahead of the passengers left knee.
You can get used motors from a junk yard pretty cheap.
Good luck

2004 CHEVY SUBURBAN FRONT A/C WORKS BUT THE REAR DOESN'T TURN ON


There is a blower motor control processor for the back blower - it takes input from the front control and the rear control and decides the fan speed. That processor could be faulty, or the blower motor, or a 30amp fuse in the engine compartment.
In the front system you have a controller and blend doors that direct air thru the heater core and evaporator. You would need to check the operation of those blend doors.

unplug the heater motor and put a hot wire to it to check the motor if it blows if the wire gets real hot you need to change the heater blower motor. You will probably need to change the heater fan motor resistor. follow the heater fan wire and it will go to the resistor

Sounds like the blower resistor. It will either be located in the engine compartment outside the motor or inside the vehicle inside the blower motor cover. It could also as well be selector switch

My chevy ac blows only on fan speed 5 what could it be


It is a 99% chance you need a new fan speed resistor board.
It is beside the fan motor.... it sits in the heater/AC duct work to use the air flow to cool itself.
It costs about $35 and takes 15 mins to change.
Did you loose one speed then another and now only high works?
That's the usual way they fail.

Heater works but fan doesnt work


on the inside of the fuse box door there is a list of what each fuse is for, fuses will be numbered with coresponding numbers and explanation of what there for. also if fuse is ok, chanses are its the resister, its located behind glove box on top of heater box 2 screws hold it in heater box, electric plug with 4 or 5 wires going to it. i just went thru this with my 1995 chevy 1500 pick up. but before you go thru that chk. fuse, chk motor, run 12 volts direct to motor see if it works. now did the motor just quit? or did it work on a couple of speeds before it quit? well at any rate if the motor runs when 12 volts are put to it odds are its the heater resister.
