I have a 96 del sol Si but now no vtech motor
my radiator fan wont turn on
I have checked the fan its self it works
I checked the fuse block and relay they are good
I ohm metered the wires to the fan plug and there good no shorts
The fan did work when I swapped the motor in.

only thing I different now is no condenser or ac pump
and 2 vetch plugs bare

not sure to much on these cars took me 2 days to figure out the fuel pump is power runs away then back to the pump

 

did you bleed the system correctly? the temp switch might be bad try jumping the connector see if the fan turns on. but make sure its bled correctly 1st
