how do I lubricate the heater fan on a 2005 volvo xc70

Hello, Is the heater fan squeaking or chirping? If so, the solution is just a replacement. The bearings are sealed, and once they wear out, that;s it. Removing the glovebox may not be necessary. Below the glovebox there is a round plastic component that hangs down, just a few inchis in diameter. That is the motor, and it is removed as an assembly with the fan. You may have to remove a cover to expose it, but I don't think that is the case. your best bet is just googling a picture of your make and model plus 'blower motor' for better identification.
