Finally got a chance to hook up INPA. First read codes and saw nothing related to cooling/Aux fan. The. Tried manually activating aux using INPA and was unable to do so. INPA showed aux on but the fan was not moving. AC was not blowing cold either. Went for a drive and the cold air started blowing and so did the aux fan. So it sounds like the aux fan is bad. But wouldn't the ECM have codes stored regarding it if it was bad?

Also I found a Behr Aux fan at FCPEuro for $360 and free shipping. Sounds too cheap to be true! Is that legitimate site?
