I have a 90 sc that the cooling fan wont work I have replaced the fan,the IRCM
Checked all fuses breakers & fuse links is there something else jumped the fans
to battery & it worked
 
low or high speed not working? or both of them not working? did you verify that the ICRM is actually working? have you swapped it with a known good one?
 
the only other thing would be the sensor near the thermostat
my fan doesnt kick on till the guage is close to 5/8 on the temp guage . i think if you start the car 2 or 3 times without going above 35 mph the fan comes on every time you start it

Are you sure it's not working? I thought mine was not working in low speed and even replaced the IRCM (even though it worked during the EEC tests). It would only come on while sitting at idle for long periods on really hot days and only in high speed mode. Then I read deeper on here and found out that low speed will not come on unless the AC is on. Since my AC doesn't work (bad drier), I jumped out the pressure switch and unplugged the compressor clutch so I can run it in low speed.

I'd say to try that, put a jumper on the AC pressure switch and unplug the AC clutch connector then run the car w/ AC on to see if the fan comes on...
