i connected a direct positive and negative source to the fan to see if it will come on and it did not. I followed the instruction from here. Troubleshoot Auxiliary Cooling Fan - Component checklist and notes looks like the same connector. I'm thinking the fan is bad. I just want to make sure before I go out and spend $600 on a new one. Can someone confirm I"m on the right path and any suggestion on cheap alternative to the fan other than the dealer? Thanks!
