90SC cooling fan won't work

Does anyone know a check or test of the ICRM? My cooling fan won't work (motor is good in both speeds, if I drop 12v across just the motor)... I think it has to be either the 12v fuse link to the ICRM or the relay unit itself. The A/C compressor won't engage either, so I believe it's in the relay. I found a used IRCM at the junk yard, but that didn't work either. Any thoughts? Thanks.
 
Where in MI are you? I am working in western MI now near South Haven. I have a Rotunda IRCM Tester that will test the IRCM functionality quickly.
