Question Diagnosing oil cooler fan issue

I have an '89 930 that I suspect may have a non functioning oil cooler fan. I pulled the relay and jumped pin 85 to ground and, with the key on, did not get the fan to come on. What is the next step in checking functionality? Anything short of pulling the cooler and bench testing the fan? Thanks for the help (pictures are always appreciated)
