Default Heater/AC fan not working

Does anyone have an idea what could be wrong, like the fan motor?

What's going on? You really need to describe the problem.

Default Heater/AC fan not working

Well, when i put the key in the ignition, and turn it to where the dash lights come on or when i start the car, the 'REC' and 'AC OFF' buttons blink for like 30 seconds, and when i adjust the speed of the fan, there is no response...oh, and sorry that i wasn't very descriptive in the post above.

I would check fuses, if they are good pull it and put 12V to it to see if it kicks on. Be careful because they jump if they work. If it doesn't work you'll have your answer.

If the fan works, you likely have 1 of 3 problems:

1. Bad climate control box.
2. Bad relay (105) at the fuse box.
3. Bad resistor.

Is your system ECC or MCC? ECC has numbers on the temperature dials.

Pull the fan and put 12v on it to see if it comes on then.

Default RE Blower Motor

This is my blower resistor. Are there any visible faults?
