Hello I will help you with your question,
If you have a 12 volt testlight or a voltmeter I can help you check the blower circuit.
Let me know so I can help
All along the way look for burnt or melted connections
Unplug the blower motor and see if you have 12 volts at the pink/light green stripe wire with the key on and if you do plug it in and check at the dark blue/yellow stripe wire from the wire side to see if you see the same reading.
Use a paperclip or straight pin to probe inside the connector to make contact if your meter leads will not do it.
If you have power through the blower it should run on high even without the blower resistor. The speed control switch provides the ground for the motor.
Let me know what you find and we can move on from there.
I will be here for a couple more hours and your question never closes. Just login to the Just Answer site and make a post to THIS question with the results and I will be notified that you have posted.
Let me know what you find
When you look up to the blower motor you don't have the pink/light green wire just the dark blue/yellow?
And there is a Blue wire running to the motor?
Follow the wiring from the blower resistor and tell me the wire colors there.
This has a rotary switch for the blower speed with 4 speeds?
Let me know
OK, I see you have 2005 wiring, treat the blue wire as the pink/blue wire and let me know if you have power to it with the key on then plug it into the blower and see if you have power at the dark blue/yellow wire.
Turn the blower switch to the high speed position and measure the dark blue/yellow wire again and let me know what you find
Ok do you have power on the blue wire?
Did you plug the connector in and see if that power is carried through the blower on the dark blue/yellow stripe wire with the speed switch on 4??
Sounds like the switch contacts are burnt. The procedure below shows how to remove the control head to replace the switch.
Click here for procedure.
You can put the meter on the dark blue/yellow wire and leave the blower connected then see the voltage jump and fall as you move the switch to the high speed position, if it goes back to 12 volts when you are on 2 or 3 or even 1 and 4 and the blower does not run you have high resistance in the switch and it needs to be replaced.
You can find a used control through car-part.com or the dealer should be able to supply a new one.
