My blower motor is not working why?

I have a 2006 chevy truck dual control auto temp I have tested the wires at the fan and i'm getting power on the purple wire that plugs into the fan one thing I noticed there is a small purple wire coming into resestor and it has no power to it. Can you help me please

I did that test and I have no power, yes the purple/white wire that comes into the resistor it says input on the resistor. I took fan out and hooked power and ground to fan and it worked like that. The doesn't work on any speed when it stopped it was like some1 had turned the speed down slowly. The it stopped. Thanks for the help

Ok thanks I think we have it its the heater control panel in the dash.

The fan speed knob in my truck started malfunctioning a short while ago. It started with only the number 3 and 5 setting not working and eventually ended in none of the settings working. Is this a blower motor malfunction or something like a wiring harness? I'm stuck.

I replaced the blower motor resistor and the problem is gone thank you for your help.

I don't know for sure what it is but the blower motor doesn't work anymore. Last weekend I unhooked the battery and then hooked it back up. I didn't notice it until Monday morning on my way to work that the blower motor quit working. It doesn't work in any speed at all. My question is How can I tell if it's the motor, the resistor, or just a simple fuse. I did check the blower fuse and all of the A/C fuses under the hood and on the inside but nothing around the blower motor assembly. Please help.

I had a mechanic look at and we found that the wiring harness going into the Blower fan resistor had burned out. He told me to get a new resistor and wiring harness and how to hook it all up. I then asked him if I needed to replace the blower fan and his response was get everything else fixed and then with the fan running hold my fingers on the wiring connector see if becomes hot. If it does then the blower fan needs to be replaced. My question to you is Do I really need to replace the fan even if it gets warm or hot?

The fan come on when he touched the wiring harness but when he put his fingers on the wire it started getting hot. That's when he told me I'll probably need a new blower fan. So I got a new one and its fixed thank you

Please where is the fuse for the blower motor I dont finned in the fuse box

The AC seems to have stopped working with no lead up until it simply stopped blowing cool air. I am not sure if it is simply a fan blower issue or if the whole unit stopped working. When the heat is turned on it still produces heat but nothing is blown out. Has anyone dealt with this issue or have an idea of what may be wrong with it? Thanks in advance for the help.

After having a ignition switch replaced at the local dealership my fan motor quit working a few weeks later. Last week I took it back to the dealership and was told there is a resisitor bad causing the problem. In order to replace I would need to purchase a new pigtail which the resistor was built into at a cost of over $250. I feel the dealership was pulling my chain. Any advise? If so are there any wiring diagrams aviable?
