Heater blower motor

[Ohioan]

2005 Saab 9-5 Arc sedan. 113K miles.


The blower motor for the heater/AC has been acting up over the past month. At first, the fan speed was very low, even when the speed was set to maximum, but would reach full speed after about 10 minutes or so. Now the fan is not working at all. The climate control display seems to be working O.K.


So is the blower motor bad? Or perhaps it’s something else (e.g. resistors)?


Thanks

Start with doing a calibration and check for any fault codes of the ACC: http://saabworld.net/showthread.php?t=28199
