The car is a 2004 Boxster S. AC and air worked perfectly yesterday and now when I turn on the air I can hear the vents opening but the blower does not turn on. Everything seems to work fine on the control unit. The blower does not come no matter what the setting, (manual, auto, AC on or off). I checked the fuses and they are good. I switched a few relays around and no luck. I also saw a few posts about the key ignition position but it doesn't seem to make a difference. The wipers work fine. Anything else I can check before I have to pull the motor? And what is the right way to test the motor?
