Default Blower motor- how to + cost

Does anyone (hopefully Tech) have an estimate of a fair price to install/replace a blower motor? I've also toyed with the idea of installing it myself. Any suggestions or anywhere I can find tutorial pictures/steps tio install?
I have a 2003 S40, 45K and when I turn the fan speed on (off auto) there is no sound so after reading in here, I assume it's a bad blower motor.

I'd bet that it's the blower motor resistor. A quick search for "blower resistor" will come up with a ton of hits.

Replacement of the blower motor should be 0.6 hours of labor and a $250 part.
Replacement of the blower motor resistor unit should be 0.3 hours of labor and a $84 part.

If you're handy with a soldering iron, you can even replace the individual resistor component for under $10.

Many thanks. I now feel like I will be able to change the motor and resistor myself.
I found a great post with step by step pictures on a 99 v70. I just need to figure out how to get the glovebox off my '03. Hopefully it's smooth sailing from there.

2 Questions:
1) Do I need to disconnect the neg. battery cable?
2) If so, will I need the code for my stereo?

I did not disconnect my neg battery cable but it's always a good idea. It's up to you.

You can check the blower motor yourself. Remove the cover under the dash, behind the glove box. You will see the blower motor in the far right corner. Disconnect the electrical connector. Now hook a short wire to ground and a long one to your positive battery cable (if you left the battery connected). The blower motor should run at full speed. If it does then I'd bet it's the blower motor resistor gone bad. Replace the cabin air filter while your there. Mine was clogged and the lack of flow killed my resistor.

You can have it done QUICKLY, done INEXPENSIVELY, done CORRECTLY. Pick any two.
