Why does the blower motor in the front only does not work at any speed the rear blower works and is warm it is a 2003 suburban z?

There is a heater resistor that is located under the dash on the passenger's side of the truck. You have to remove 2 5/16" screws to remove the cover, then 2 1/4" screws to remove the resistor. There are 2 electrical connectors,1 to the resistor and 1 to the blower motor. Use a small flat screwdriver to release the connectors with out breaking them. I could not find the part at any local supply place, had to buy from the dealer... Keep your receipt, I have replaced mine 2 times at 100$ a pop. The first one lasted 3 months and I didn't save my receipt (it had a warranty). I was also told the blower motor might be causing the resistor to go bad, so if it goes out again I'm replacing the blower motor too. I hope this helps you.

What is wrong if your blower fan motor only works on high speed on a 2002 Chevy suburban?
blower resistor is bad
Why doesn't 1997 Chevy Suburban's dash board blower work?
If the blower works on the defrost mode only, you could have a disconnected vacuum supply line coming from the engine. If the blower motor doesn't work on any mode or speed you could have a blown fuse, burned out blower motor speed resistor, bad switch or a bad blower motor.
Does the front and rear blower on a 2003 Tahoe use the same resistor pack?
If it has separate blower speed controls for the front and rear, it has separate resistors. Blower speed resistors are mounted close to the blower motor it controls for cooling purposes.
What is the purpose for the relay fuse for the blower in the 1993 Cadillac deville?
The blower motor fuse protects the blower motor electrical circuit. The blower motor relay operates only the high speed function of the blower motor. The blower motor speed resistor operates the lower speed functions of the blower motor.
1998 Chevy suburban blower motor does not work at any speed Fuses look ok any ideas where to look next?
If the blower motor does not run at any speed, and you are positive the fuse is good, then it is either a defective blower motor, blower motor speed control, bad Blower Motor Resistor Pack, or loose, corroded, or disconnected wiring. I would replace the fuse even if it looks good before going any farther. Apply 12 volts directly to the motor to see if it is good.
1999 Suburban the fan blows on low speeds but not on high?
Could be hi-speed fan relay or secondary winding in blower motor
Blower will not blow fuse is good?
Defective blower motor, blower motor resistor pack, or blower motor speed control switch.
Your ac want blow how do you fix it?
If you are saying the blower motor will not work, then check the fuse. If the fuse is not blown, then it is possibly a defective Blower Motor Resistor Pack, blower motor, or blower motor speed control switch, in that order.If you are saying the blower motor will not work, then check the fuse.

What does the blower motor resistor do on a 2001 prism?
The resister for the 2001 prism blower motor drops voltage to the blower motor. This is how the blower motor runs at a lower speed.
Is a blower motor speed controller the same as blower motor resistor?
yes indeed
What does the blower resistor do in a 2006 Chevy Express?
The blower resistor controls the speeds of the blower motor Hi-resistance lower motor speed Lo-resistance higher motor speed
Your heater blower will just work on high speed?
The blower motor speed resistor is burned out. The high speed function bypasses the resistor. The speed resistor is generally located near to the blower motor.
