heater blower motor on 2004 Dodge Dakota

I have a 2004 Dodge Dakota truck that has no speed control for the heater fan. I checked the fuse and it seems to be fine. I just learned about the heater blower resistor. According to a few answers on this site, if the resistor is bad the highest speed should work. Mine does not. No speeds at all. Not even when I had the A/C on this summer. I need to get this fixed. Any answers?

I would check for power and ground signals to the blower motor. If they are OK, then the motor is bad, if you are not getting the proper signals, then the circuit will need to be diagnosed to determine what is wrong.

How do I remove the dashboard to check this? Or do I check this at the fuse box?

You'll need to check this at the heater blower motor. If you don't know how to access the blower motor, you should get a repair manual, you can find one at alldatadiy.com for less than $25.00 and it's an online manual so you will have it in minutes. If your not experienced with electrical diagnosis, you may want to take this to a repair shop, you may save yourself a lot of time and money!
