SOURCE: the heater blower on my 2003 GMC sierra wont shut off

i had the same problem. depends what kind of trim model you have. but if you look on the passenger side floor right under the glove box is where your heater unit is. if you take off the cover to it. their will be a little squarebox looking thing with 2 - 3 wires coming out of it and goin to the blower motor unit . Tap the square box with a screwdriver while your blower motor is on off mode. it should shut off if you give it a couple good solid taps. dont be afraid to hit it. that little square thing might have to be replaced if it turns off when you hit it. or just may have to be cleaned.

SOURCE: 2003 GMC Sierra heater Blower wont shut off

My 2003 Sierra's blower came on by itself in the garage while I was sleeping and ran the battery completely down. I had to replace the blower switch located under the glove box next to the blower at the bottom of the right corner of the dash. The switch is in front of the blower and held in by two screws. Disconnect the two wire connections. This is a "dealer only" part and cost me 65.00. Also check the wire harness with seven wires connected to it for melted plastic. It will be marked "ABCDEFG". If it has melted, you'll need to replace it. Pay attention when reinstalling either part, that the wires "ABCDEFG" match the switch in that order.

SOURCE: gmc sierra blower switch

last place to look is the resistor block located in the duct work for the blower (fan). it should have a wiring plug going to it and be held in by a couple screws. look on the passenger side near the fan itself.

Heater blower hooked up not working new resister and all good fuses
The heater blower motor needs to be checked.If the resistor is replaced but still the motor is not getting started then its faulty heater blower motor.Get the 12 volt checked by meter to confirm power to the motor.If no power then its faulty motor causing this problem.

99 Dodge durango heater not working
The blowers ion the back have there own blower motor. The front has it's own. The resister controls the range the blower motor runs on,( low, medium, high). If the blower motor is not working it may be the motor itself. Was the fuse checked:?

Heater fan on 2002 Yukon does not operate in front, only rear.
The front blower motor is controlled by the blower resistor module.This is usually the problem with the front blower not working.I looked up the schecmatics and I don`t see separate fuses for the front and rear.But the fuse for the front blower is in the under hood fuse block.If this is good then The problem is probably the resistor module.It is next to the blower motor.The connector from the resistor connects to the blower motor.If you want to confirm this you can check for power and ground at the blower motor connector when you activating the blower switch on.This can be done with a test light.Make sure you have power going into the resistor module also.If you have power going in and no power at the blower motor then replace the resistor.Hope this helps.Good luck.

No Electrical Power to Heater Blower
First thing to check would be the fan speed resister, fan(blower-motor)relays, and possibly a bad ground. Start at switch on the dash and go to the relays and resister next.

Blower for heat.
If the blower is totaly not working it could be a bad motor or a loss of power (or ground) to the motor. There is a blower motor relay on the power distribution box on the right innner fender. There may be a fuse for the heater circuit, also. Power also goes through a blower motor resister that controls blower speeds. If any one of these are bad it will (can) cause the blower motor to not work. I would first check all your fuses. If you have the ability to check for power continuity (with a test light or multimeter) I would check to see if the motor is even getting power. It is also possible that your heater control switch is not sending power to the relay. Electrical can be hard to track sometimes. Good Luck.

2001durango slt no heat in front
I have a 2001 Black Durango that had the same problem. There is a resister to the right of the ac/heat blower (underneath the dash on passaenger side). This needs to be replaced. You might want to replace the motor as well. Both are real easy. I had replaced the resister first and everthing worked fine for about 6 months and then my ac/heat would only works on high. I replaced the motor and now it works just fine. The resister was about $15 at dealership and the motor is prob around $40-$50. I hopes this helps. Good Luck!
