The blower for the heater/AC on my son's 2008 Impreza WRX (non-STI) stopped working. No fan or air movement at any setting. It's the automatic climate control version.

 

I checked all related fuses in driver side interior fuse block. They're good.

 

He says the fan surged a couple of times during use so he turned it off. The next time he turned it on, nothing.

 

Where should I look next?

 

Thanks.

If the fan speed control is variable and not a few different speeds then the trouble may be the speed control module. It varies the available power to the motor and has to supply the current to it. Be sure to check the fuses under the hood also.
